Bitcoin can be hacked?

[Major_Troubles]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

No, it isn't.

[tranle789]

I think Bitcoin can not be attacked because Blockchain technology is now growing and no one knows how Bitcoin was created. Only exchanges are attacked and this really does not affect Bitcoin

no i doubt it,with all the technology and mind inside bitcoin industry that conceptualize,and with the highly security blockchain has,no one or no body can hacked bitcoin,thats for sure

[rarkenin]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

If you talk about bitcoin wallets, answer is yes! You are responsible to securely store your bitcoins. My advice is to afford 80 bucks for purchasing hardware wallets like trezor,ledger.

[Baofeng]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

Can you give us one scenario that bitcoin has been attacked before?

Blockchain, the underlying technology behind bitcoin has no history of such attacks, although it has been spammed before causing the network to clogged down a little. And with regards to bitcoin wallet, its your own responsibility to protect it against hackers, like having strong passwords, 2FA and secure your private keys. I hope you can research first before posting here because it looks like you don't have a clue what bitcoin/blockchain is.

[edynolan]

I think bitcoin can not be fi hack because it's hard to do, what hackers do is take your bitcoin because you give a little gap where you do not give security to your account

[Mr. Mohit Sharma]

Techonology: It's Not
if we are talking about the user perspective that can be possible!  

[salihno71]

The weak link here is human. If you don't take precautions, it is possible. You should keep your wallet and private keys safe. Directly, it is not possible like via brute force or some other known method.

[TooDumbForBitcoin]

Techonology: It's Not
if we are talking about the user perspective that can be possible!  

If somebody will get 51% of hashrate then technologically also possible. You can also learn about all bitcoin weaknesses from http://en.bitcoinwiki.org/Bitcoin_weaknesses

[khaled0111]

If you mean hacking wallets, then yes, wallets can be hacked and many users got hacked before and many others will be in the future because wallets security depends on the user himself. But if you mean hacking the Bitcoin as a running network, I think that will be hard if not impossible because the concept is based on decentralization and with more users accessing the network the security becomes stronger and stronger.

[VitKoyn]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

It depends on what you are referring. Bitcoin can be hacked through Bitcoin platforms like exchanges and hacking users device where they store their bitcoin wallets and private key. But if you are referring to Blockchain which runs the Bitcoin network it will be hard and is very unlikely to happen. The blockchain can't be tampered with unless some malicious nodes get more hash power than honest nodes (greater than 51% of the hash power of the network). It's very expensive to conduct a hack on the network as the computing resources required to do so are immense.

[monkeydominicorobin]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

How can you attack something that doesn't take your username and password. The 51% attack is their best mode of attack but there are contingencies in place. Besides it is more profitable to allow Bitcoin to persist. So no one will make that attempt. For this mode of attack is very expensive. Not even affordable ever.

[aplistir]

I think Bitcoin can not be attacked because Blockchain technology is now growing and no one knows how Bitcoin was created. Only exchanges are attacked and this really does not affect Bitcoin

Of course it would affect bitcoin.
A successful attack, where someone steals huge amounts of coins from an exchange would be very bad for the value of bitcoin. Remember MtGox?
Such attack would erode peoples trust in bitcoin and crash its value even if it would be caused by exchanges bad security.

 

[sukoon]

The biggest threat to Bitcoin cybersecurity startup focused on banking. It’s always been people, and it always will be people. There are good people, and there are not-so-good people, and those not-so-good people want to grab hold of your information. If you leave that information in the hands of let’s say, seven miners, then at some point those not-so-good people are going to go to one of those miners, and that miner is going to be exploited — whether they know it or not.”

[Major_Troubles]

I think Bitcoin can not be attacked because Blockchain technology is now growing and no one knows how Bitcoin was created. Only exchanges are attacked and this really does not affect Bitcoin

But there people creating a lot of new "bitcoins". For example - christcoin (actual religious coins ).

[Cryp2]

If you are referring to bitcoin as blockchain platform ,then it's very hard ( if not impossible) to hack it since it's highly secured but when talking about exchanges platforms and stored wallets in devices , then yes , hacks can affect user data and can harm his privacy .

[bit-freedom]

I haven’t heard of Bitcoin Blockchain being hacked but there are plenty of cases of BTC wallets and exchanges being hacked.

For users, the hacks are usually because of private keys being stolen or scammed. This is why we have to keep private keys safe and not store in computers that are vulnerable by malware attacks.

[sofi@]

Bitcoin is very safe unless you are careless enough that your passwords are stolen by someone, but those online wallets are design privately so that only the owners can have the access over it without worying somebody can also access it so I think its impossible for bitcoin to get hacked by someone.

[kpcian]

I don't think so. Bitcoin has been invented in a highly secure mechanism. so that Bitcoin hacking is not possible, though, in the technical area, Nothing is impossible. But many experienced hackers have made a lot of abortive effort to unlock Bitcoin platform so it can be said that Bitcoin is going to be hacked anymore.

[ChainSmoker]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

Bitcoin is backed by cryptography and can not be cracked/hacked by current technology.If you mean can your personal bitcoins be hacked?Sure,if you do mistake by installing malware or some other mistake then sure but otherwise no one can hack your bitcoins from the network itself.In future,we can't say if it will be impossible to hack bitcoin when we have Quantum computers but i am sure by that time bitcoin developers will come with powerful solution to upgrade the network.

Just heard from some experienced people here or maybe read it from the past that your saying is obviously right, it needs resources to hack bitcoin than the resources your'e going to obtain by hacking bitcoin. even duplicating bitcoin is just really hard.
I heard that bruteforcing the bitcoin private key is possible but needed thousand years just to crack a private key.

[Opquar]

There will always be ways to sidestep any security feature. No security system is perfect, and you, the user, are prone to mistakes. That being said, Bitcoin is nearly impossible to hack, but a breakthrough in quantum computing can change that quickly. Your machine can also be compromised, or you can be phished. Everything has a vulnerability.

[passwordnow]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

Welcome to the bitcoin world and this type of question are for real newbies out there. And the answer is no, you can't literally hack bitcoin or the whole blockchain network. What makes it possible to hack a bitcoin is by doing some phishing to the bitcoin owners that aren't aware they are being phished. This is the usual event that's happening of those people who are complaining about reduction of their bitcoin balance.

[pinoyden]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

yes its possible because bitcoin works mainly on  online and it can still be prone to viruses and malwares unless you transfer your coins to a hardware wallet like trezor or on a cold storage like an offline computer, in that way you can assure that your coins are 100% safe and free from hackers.

[scarell]

as developers bitcoin so the malware developers are gaining experience ... maybe could be hacked, but unlikely

[kuronokishi10]

According to me,no,it cannot be hacked,as no one knows the bitcoin origin and how exactly it came into existence, i mean the method or software used.
Mostly bitcoin transactions are hacked and that too happens very rarely since these days we wait for multiple confirmations.

[Rajat97]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

If you are talking about having it there is no possible way because there is as such no source where the bitcoins come from. There is no place where the bitcoins are situated. Bitcoin is not a stable currency but will end in a few years and other crypto currency will take place of bitcoin. Later these currencies will be valid in various countries and will be used for even transaction purpose.

[ninabobo]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

has many rumors about what you say. on the fact that you have to accept. bitcoin still survive to this day. you can see so great value. but bitcoin remains safe until now.

[majeed]

Bitcoin can be attacked, even be hacked. However, the possibility is even smaller than an airplane will crash on you in the next 2 seconds. Therefore, we can say that bitcoin can not be hacked. In the future, maybe people will invent a very strong computer which can encrypt everything in the blockchain and hack it or the world will born an extraordinary intelligent person who can solve all mathematics on the world

[prodifter]

Yes, that can happen
In the past there were many times hacked hacked, even many large decks with very high security
And when hacked the amount of damage is enormous

[Koadharber]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

When we do speak direct hack on bitcoin then its not possible since bitcoin is a decentralized stuff no one could able to hack or modify it which means no one can able to control it.Just being said above the only thing here is that those services who do make use of bitcoin and other cryptos would be the only one who can be hacked which would really make effects on bitcoins price.

[btcdepo]

Unfortunately yes it is being hacked everyday. you should be very careful where and how do you store your coins.

[keeee]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

Yes it is possible for a hacker to hack all the bitcoin that you have in you wallet. If you have a lot of bitcoin your wallet, i recommend you to use some high security wallets and dont just put all of your bitcoin in a single wallet. Seperate it to different wallets. Also, be careful with your accounts and passwords. Dont just tell it to anyone even to your friends or families. Keep it private as much as possible.

[paolo099]

the nature of bitcoin makes it unhackable (decentralized technology), speaking of wallets/websites/exchanger yes, depends on the security applied to that.
Wallets, login to sites and so on are always under the hack risk because of short passwords, no strong security (saving passwords in plain text).. and humans are the easiest "thing" to hack, with some public relashion you can get very close to get into other accounts.

[btccashacc]

Basically, bitcoin cannot be hacked as long as you keep your private key safe then your bitcoin will be safe. Many cases out there where people stored their bitcoin on exchanger or centralized wallet got hacked, this is obviously their fault to storing their money in unsafe place or giving someone their private key. The point is if you understand how to secure your bitcoin properly then it can't be hacked.

[batang_bitcoin]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

We all love the concept of bitcoin and this is the reason why we are staying here. And regarding to you question, bitcoin can't be hacked but what can be hack are those web wallets and exchanges. That's why we have to be responsible when it comes to keeping our bitcoins. And also you must be aware of what sites are you visiting because you may not know there are some malware or scripts that when you unexpectedly click it, that's a clickbait and also always look at the name of website you are visiting because hackers are trying to misspell the real websites in order to get some victims.

[quovadiz]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

I don’t know reality about hacking of bitcoin but I think that bitcoin cannot be hacked but accounts in investment or on exchanging of bitcoin can be hacked, and bitcoin is a cryptocurrency, digital currency and a lot of people have support for bitcoin and make the system of bitcoin more advance and secure and no one will get bitcoin through hacking etc.

[Chiggins]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

no i doubt it,with all the technology and mind inside bitcoin industry that conceptualize,and with the highly security blockchain has,no one or no body can hacked bitcoin,thats for sure

I don’t think so that bitcoin can be hacked but if we pointing about wallets then the answer will be yes! Because a lot of people lose their bitcoins due to weak wallets, here the good thing is that we all need to save our bitcoin is safe and secure wallets and all I know about bitcoin top wallets are trezor and ledger which people love the most and all of them save their bitcoins there safely.

[jankekek]

No, but it depends of you how to safe your bitcoin. more people are hacker.

[bebejhen]

I don't think that bitcoin can be hacked. Our account cam be but not totally the bitcoin. Our accoun is like our account in social medias there is an email and password so we must keep our password safe and private. As well as our bitcoin addresses.

[A.nayem]

It depends on what you are referring. Bitcoin can be hacked through Bitcoin platforms like exchanges and hacking users device where they store their bitcoin wallets and private key. But if you are referring to Block cain which runs the Bitcoin network it will be hard and is very unlikely to happen.

[taiwww]

The complete working of bitcoin depend on its security system blockchain.
If any hacker breaks this blockchain then and then only he can hack bitcoin.
Blockchain is a distributed and decentralised public ledger in which all the bitcoin transactions made get recorded.
It allows bitcoin traders to keep a track of all the transactions made.
The blockchain was designed so that all the transactions cannot be deleted.
If anyone has to hack the blockchain then he has to take control of all the nodes connected all over the world, which is impossible.
We may lose bitcoins if we are not using secured  bitcoin wallets.
Its our responsibility to protect our wallet from hackers by keeping strong password.
And also by keeping secure your private key.
"Thought it is quiet difficult to hack the blockchain expert says its not impossible."

[Marileno]

Usually what happens is people are third parties are hacked. The same way that it is super rare to hear that a bank was hacked. Hackers and criminals will always find a way to  commit fraud. Sometimes it will involved hacking individuals themselves, or even exchanges and wallets. Education users and forcing exchange and wallets to secure their data in certain ways is very important to limiting the occurrences of fraud involved BTC, which of course helps the velocity of main stream uptake.

[MattHoo]

Of course, not. Bitcoin can not be hacked, but if you put it in some unsafe wallets then may be it can be hacked.

Yes that is right no history that the block chain was ever compromised by the hacker, hacking incidents only happened on wallets and exchanges.

I saw an speculation that in order for someone to compromise the blockchain transaction you need to have at least 51% of the blockchain but the problem is no one knows if what is the exact number of hardware is connected to that system.

[newlone]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

When the value of any bitcoin is too high, the hacker will be interested in it and bitcoin is a choice. But the security of bitcoin is high so hacking is very hard at present, but in the future it may be the target.

[yugyug]

blockchain is the backbone of bitcoin technology, the integrity of its key and ledgers  is hack proof and tamper proof. the only way to unlock its
security is the the thing called "private key". if private key is lost breaking the code like key guessing or what we called as brute force is nearly impossible. but always remember this , that the chain is as strong as its weakest link, the weakest link here is the "private key" once it is breached or leaked then, the bitcoin transaction can be easily hacked. the only way to exploit private key is thru social engineering, like sending key logger files to the victims pc or sending some phishing site where it world ask about something of your bitcoin details. so the security of your bitcoin data lies on your hand on how you handle spam and other malicious files and website. regular updates of internet security tools might also helps.

[jc89]

Bitcoin cannot be hacked. Its value is secured due to the cryptographic functions that it employs. Maybe it could be hacked one day in the future but such an attack is unlikely to happen in the near future. However, the networks and storage locations or the exchanges can be hacked. There have been reports about it and the most prominent case is the Mt. Gox attack in 2014.

[rajsimran]

Yes bitcoin can hacked.If hackers put key logger on your computer they can transfer all of your bitcoins.If you download any virus or wallet which infected in  virus they can hack your bitcoin.I saw a post which made on 10 October and he lost around 95 btc which was hugged amount of btc.He lost his btc because hacker put a keylogger in his pc.My friend lost 2 btc few days ago.He downloaded a wallet which infected in virus.So your bitcoin can be hacked in various way

[Mame]

No, it isn't.

It is impossible to hacked bitcoin, the concept behind bitcoin is what I like the most the privacy behind bitcoin. So it is really imposibe ti hacked or be stolen

[jkoin]

Most likely, it is impossible to break the bitcoin, or just no one else has found such a method. But as practice shows - nothing lasts forever. Yes, the crypto-currency industry is still too young and will grow and develop for another 2-5 years, this is 100%. But it will take off, there will be a fall.

[CryptoScorpio]

It depends on us.Actually Bitcoin was developed to be very safe currency.But there are few cases where bitcoin got hacked. It is impossible to hack bitcoin but it it is easy to phish you out and take your money.So it is in our hands to take care of our systems and private keys.

[braves182]

It depends on how much you are responsible for storing your crypto currency. You should choose the most convenient and safe wallet. I use Blockchain.info, for me he is the most secure. It has a two-factor authentication system, SMS-notification system, codewords, double passwords.

[Smith871]

NO bitcoin can never be hacked because they are organized by well developed and well trained team as even now no one knows who developed the bitcoin so how one can hacks their such a big economical organization.

[splat44]

It depends on how you handle your wallet, try to keep your private keys and phrase password it's very important. but if you asking if Bitcoin can be hack? No one can hack bitcoin. Unless you're the real Satoshi Nakamoto. cheers brother

[bagsk]

What about this - https://lbc.cryptoguru.org/trophies

Excerpt from FAQ

The "Large Bitcoin Collider" (LBC - a homage to LHC) is a distributed effort to find at least one collision of private Bitcoin keys by creating addresses to private keys in a continuous 2¹⁶⁰ range. These are checked against the list of known BTC addresses with funds on them. In the rare event of a collision, the funds on the address in question would become accessible to the collision finder.

[jeraldskie11]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

If bitcoin has possibility to be hack, I think the volume market capitalization of this currency will not reach $88 billion. Professional investors are very wise, its about the money so they don't put it risk. So if they know that bitcoin is not secure, there is no reason by the developers to born this currency.
For me, there is no chances for hackers to hack bitcoin, that's all.

[salihno71]

Well, here you can find the list of currently known weaknesses: https://en.bitcoin.it/wiki/Weaknesses If you are thinking on brute force the private key, here is the another post:

How long in bytes the private key is

32 bytes, or 256 bits

then how many combinations of numbers it will contain

There are 2^256 different private keys. That's a little larger than a 1 followed by 77 zeroes.

what is the fastest computer or network of supercomputers

At its peak around August 2011, the Bitcoin network was checking 15 trillion sha256 hashes per second. (See http://bitcoin.sipa.be/)

how long it would take to crack a private key using that computer

If we assume it takes the same time to run an ECDSA operation as it takes to check an sha256 hash (it takes much longer), and we use an optimisation that allows us to only need 2^128 ECDSA operations, then the time needed can be calculated:

>>> pow(2,128) / (15 * pow(2,40)) / 3600 / 24 / 365.25 / 1e9 / 1e9
0.6537992112229596

It's 0.65 billion billion years.

That's an very conservative estimate for the time taken to break one single Bitcoin address.

https://bitcoin.stackexchange.com/questions/2847/how-long-would-it-take-a-large-computer-to-crack-a-private-key

[ajjhu]

If you're talking about bitcoin wallets, the answer is no doubt yes.If your computer isn't secure, or no anti-virus software, hackers can easily access your wallet's private key.

[Slipknot79]

Its been a problem since the beginning of time. There will always be criminals out there in this world. Its just a fact of life I am afraid.

[harbin55]

there is a minimal chances!!!
bitcoin can be hack!!
there are lot of hackers all around the world we could not said that bitcoin cant be hack

[4hajs]

No bitcoin cannot be hacked. Only your computer can be hacked and the hacker can get access to your private keys. Thats why the security is so important when we are using cryptocurrencies. Protect yourself be paranoic, get hardware wallet.

[Alok Yadav]

No central bank or governmental authority backs the safety or soundness of digital currencies. Unlike fiat currencies like the US dollar, which is printed by the Federal Reserve, bitcoins are minted by complex interactions across a broad global computer network.

Due to the nature of digital mining, bitcoin’s value cannot be manipulated or altered. Bitcoin's value is secured thanks to the cryptographic functions that it employs, and though it could be hacked one day in the future, technology and cryptography experts agree that such an attack is unlikely in the near-term. However, the networks and storage locations where bitcoins are housed and “protected” can be hacked by malevolent forces. Despite assurances by bitcoin storage companies and developers of the currency, bitcoin exchanges can and have been hacked.

There are three prominent hacking cases of bitcoin exchanges in recent years:

Bitstamp: The Slovenia-based Bitstamp exchange represented the third-busiest marketplace for bitcoin at the beginning of 2015. The exchange processed roughly 6% of bitcoin transactions. The firm announced a breach in early January 2015 and shut down its services temporarily. When the smoke cleared, thieves had taken off with roughly 19,000 bitcoins (BTC), a fraction of the exchange’s total assets. Rather than keep its assets on live exchanges, Bitstamp had stored more of the currency on local hard drives, a process known as “cold storage.” The total heist was valued at $5.1 million.

Mt. Gox: The most prominent bitcoin hacking occurred in 2014. Mt. Gox, which was based in Japan, was once the largest marketplace for bitcoin, and processed roughly 80% of all global transactions for the currency. That was until a security breach at led to the heist of $460 million. The hacking soon fueled a price collapse of the cryptocurrency, with bitcoin falling by half in less than a year. Following the well-publicized heist and blow to bitcoin, Mt. Gox confirmed that it faced roughly 150,000 hack attacks every single second. Just one of these attacks made if possible for thieves to make off with 750,000 bitcoins and bring the exchange to its knees.

Bitcoinica: Before there was the collapse of Mt. Gox, there was the fall of Bitcoinica. Bitcoinica was hacked in March 2012, and had lost a large share of coins. Despite the bad press and the attack, the firm promised to pay back users in full for their losses and improve security. Unfortunately, neither happened. The company was hacked a second time just two months later and shuttered its website. The company said it would then repay users for 50% of their previous holdings.

This too would prove impossible. While Bitcoinica attempted to reboot, it built its entire business around Mt. Gox. However, legal proceedings were brought against the exchange, forcing Bitcoinica to let all of its holdings sit idle in Mt. Gox exchanges while the courts attempted to sort out the second case ever involving digital currencies. While lawyers bickered, Mt. Gox was hacked, and anyone who still had Bitcoinica accounts proceeded to lose anything that was left.

These aren’t the only hacking attacks in recent years. Hackers took down the zloty and euro exchanges of Polish exchange Bitcurex last March. The firm lost “between 10 and 20%” of its funds. That same month, Canadian bitcoins announced it lost $100,000 after a hacker breached vulnerabilities in the exchange’s security protocols. And Picostocks, a bitcoin stock exchange, also lost 6000 BTC in 2013, despite having just four clients trading on it. Bitcoin wallet services BIPS and Inputs.io have also reported breaches in recent years.

[Nevis]

No, it can't be hack nor altered or manipulated by someone. Bitcoin is really secured but still has some flaws. The only thing that can be easily hack is your wallet address if you are not careful.

[Wipro]

No, it can't be hack nor altered or manipulated by someone. Bitcoin is really secured but still has some flaws. The only thing that can be easily hack is your wallet address if you are not careful.

What you are saying, online wallets are can be hacked and if you share your private key or wallet.dat file means your wallet will be able to hack by the hackers in the online. If you search your wallet login via Google result means also you will hacked. Please be careful about it.
Saying be careful will not be good answer for the people asking query.

[Brigalabdis]

100% it is possible that hackers can hack your account easily if they know that you have a lot of bitcoin on your wallet. I read some news about hackers then they hack about a million dollars so it is easy to hack your account.

[Timoteus]

I think, when invent quantum computers it is possible

[CyberKuro]

Bitcoin nodes security is out of question, over 8 years and still on development, core developers keep it safe.
The most vulnerable side of bitcoin is "the person" who have entire information how to access to the address, if he forget his password, no one could recover bitcoin in his wallet, as simple as that. Even for quantum computers can not hack bitcoin, as there is a precaution nodes for it.

[Nevis]

Oh, I am very sorry. What I mean is that phishing sites are very common and that if you are not careful enough that you enter your infos to that site, you'll surely give away everything you have. Please forgive me for being inconsiderate. I'll be careful from now.


edit: I think right now, as everyone admit even those who are great developers of our time that bitcoin is really secured and hard to hack.

The firm announced a breach in early January 2015 and shut down its services temporarily. When the smoke cleared, thieves had taken off with roughly 19,000 bitcoins (BTC), a fraction of the exchange’s total assets. Rather than keep its assets on live exchanges, Bitstamp had stored more of the currency on local hard drives, a process known as “cold storage.” The total heist was valued at $5.1 million.

Mt. Gox: The most prominent bitcoin hacking occurred in 2014. Mt. Gox, which was based in Japan, was once the largest marketplace for bitcoin, and processed roughly 80% of all global transactions for the currency. That was until a security breach at led to the heist of $460 million. The hacking soon fueled a price collapse of the cryptocurrency, with bitcoin falling by half in less than a year. Following the well-publicized heist and blow to bitcoin, Mt. Gox confirmed that it faced roughly 150,000 hack attacks every single second. Just one of these attacks made if possible for thieves to make off with 750,000 bitcoins and bring the exchange to its knees.

Bitcoinica: Before there was the collapse of Mt. Gox, there was the fall of Bitcoinica. Bitcoinica was hacked in March 2012, and had lost a large share of coins. Despite the bad press and the attack, the firm promised to pay back users in full for their losses and improve security. Unfortunately, neither happened. The company was hacked a second time just two months later and shuttered its website. The company said it would then repay users for 50% of their previous holdings.

This too would prove impossible. While Bitcoinica attempted to reboot, it built its entire business around Mt. Gox. However, legal proceedings were brought against the exchange, forcing Bitcoinica to let all of its holdings sit idle in Mt. Gox exchanges while the courts attempted to sort out the second case ever involving digital currencies. While lawyers bickered, Mt. Gox was hacked, and anyone who still had Bitcoinica accounts proceeded to lose anything that was left.

These aren’t the only hacking attacks in recent years. Hackers took down the zloty and euro exchanges of Polish exchange Bitcurex last March. The firm lost “between 10 and 20%” of its funds. That same month, Canadian bitcoins announced it lost $100,000 after a hacker breached vulnerabilities in the exchange’s security protocols. And Picostocks, a bitcoin stock exchange, also lost 6000 BTC in 2013, despite having just four clients trading on it. Bitcoin wallet services BIPS and Inputs.io have also reported breaches in recent years.

i think it can be, but the question is.
how far can you go ? hahaha
that is to much server nodes, to much computer you will hack, hahaha
whenever the system still growing but not yet done for hacking, its wasting time.
the bitcoin is built by complicated system and will grow that system everytime it need.
so, can you hack it before 60s is up ?
 
if you ask me, i will give up first before you ask 

[fulmetal08larz]

In my opinion, everything online can be hacked but it would not be a piece of cake for the hackers, they would need extraordinary set of equipment, skills, method, time, etc. for the hack to commence. What we can do about this is to secure our keys and passwords, avoid clicking suspicious links, check your surroundings, have an offline wallet if you have massive amount of bitcoins, get a secure e-mail, etc. Hackers use different kinds of methods to hack, we must know how to protect ourselves from their methods.

[stompix]

I think Bitcoin can not be attacked because Blockchain technology is now growing and no one knows how Bitcoin was created. Only exchanges are attacked and this really does not affect Bitcoin

What the hell are you talking about?
Everyone but ignorant know how bitcoin was created.
Start reading:
https://en.bitcoin.it/wiki/Main_Page

There is one known attack that is possible to perform on Bitcoin. It's called a "51% attack". To perform this attack you have to have the majority of hashpower of Bitcoin network. Fortunately, this attack is too expensive and unlike to happen. Bitcoin network will be safe for a long time. Our computers are still too slow to crack encryption protocols.

Three is also a Sybil  attack.
https://en.bitcoin.it/wiki/Weaknesses#Sybil_attack

And with growing blockchain space a drop in full nodes could render the protocol vulnerable.

The thread is about the blockchain and bitcoin , not your personal wallet.
There is no hack for both of them.

[shafi alam]

maybe It will happen after few time when its will be in mainstream.  But now Everybody don't know about bitcoin.  so its too hard to hack. hack is not possible its not true, any thing can be hack.

[SaShiRaJaVu]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

Internet wont redefine currency as we know it,but bitcoin will redefine the way we saw currency and shares.You do not need to develop any further bitcoin but the only thing bitcoin need is the infinite scaling solution and if they could achieve that obstacle then it will rule the world for a very long time.Bitcoin as a network cannot be hacked but make sure you know the basics to use internet and keeping your privacy.

[Obito]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

It depends on what you are referring. Bitcoin can be hacked through Bitcoin platforms like exchanges and hacking users device where they store their bitcoin wallets and private key. But if you are referring to Blockchain which runs the Bitcoin network it will be hard and is very unlikely to happen. The blockchain can't be tampered with unless some malicious nodes get more hash power than honest nodes (greater than 51% of the hash power of the network). It's very expensive to conduct a hack on the network as the computing resources required to do so are immense.

Yeah that's right it depends on the site you are referring. Many things are can be hacked now because of lack of security. Be knowledgeable about the things you are going with.

[lvincent]

If you're talking anout the blockchain and bitcoin i think it is impossible to hack. Bitcoin is decentralized that it has it's own server or bitcoin it self is a server and every seconds it changes it encrypted key so hacker's will be having a hard time hacking it.

[MommyElsa]

Bitcoin can be hacked in your wallet if you did not secure all the password or private keys but whe you are talking about bitcoin all over the world, ut cannot be hacked because bitcoin is decentralized.

[Celsiuss]

No, it isn't.

Of course it can, but not by brute forcing to get a private key with funds. The weakest point in any security system is the person using it. By clever social engineering you might hank out the password of an innocent user of an online wallet. Or maybe you got a hidden trojan on your PC that turned out to be a RAT and it has now your unencrypted bitcoin wallet. That's why you should ALWAYS be careful no matter what, always use two factor authentication and always encrypt your password. And never store your backup phrase in a document on your PC, that phrase should be on a physical paper hidden in your drawer.

[chichigirl]

Yes, it is, it can be hacked from your cellphone or personal computer if they can get your password but if the hackers can't get the details with you, they cannot hacked your bitcoin.

[BitcoinCommodor]

Due to the nature of digital mining, bitcoin’s value cannot be manipulated or altered. Bitcoin's value is secured thanks to the cryptographic functions that it employs, and though it could be hacked one day in the future, technology and cryptography experts agree that such an attack is unlikely in the near-term. However, the networks and storage locations where bitcoins are housed and “protected” can be hacked by malevolent forces. Despite assurances by bitcoin storage companies and developers of the currency, bitcoin exchanges can and have been hacked

No I don’t think so that bitcoin can be hacked because the security system of bitcoin mining and holding is so strong that nobody can hack your bitcoin. Just relax and invest in bitcoin for making more and more money doing exactly nothing.

In my opinion investment in bitcoin is the most sensible decision made by anyone who want to invest his money in some business.

[googs84]

It is impossible to hack bitcoin network completely. If you are using unsecured mobile wallet, it may get hacked. Mobile exchanges get hacked, this has happened before Bitstamp exchange got hacked in 2015, Mt.Gox, Japan got hacked in 2014. Hacking and stealing of bitcoins is possible in mobile wallets and bitcoin exchanges but it is impossible to hack entire bitcoin network. For hacking the entire bitcoin network one has to hack all the nodes of all the bitcoin users all over the world, which is impossible. Bitcoin have great future in global finance, incidences like hacking creates bad impression on upcoming investors, they hesitate to invest.

[Boov]

Yes, it is, it can be hacked from your cellphone or personal computer if they can get your password but if the hackers can't get the details with you, they cannot hacked your bitcoin.

Yes it can be hacked either you use computers or laptop or cellphone. I think hackers are too curious and so wise to be able to hack your account. So I think make your password long enough for security purposes because you didn't know if when your turn that your account can be hacked so make it secured enough.

[awaramalik]

Set up an exchange, get lots of people to deposit their BTC, claim theft of BTCs, file for bankruptcy, recover some of the BTC.  Quietly shut down and live off the value of the BTC acquired.  I wonder if anyone has done this yet?

It is possible if you haven't secured enough your wallet, or if your password or/and email get hacked or stolen. You need to secure your wallet and link it to your phone if you are using the online wallets and choose complicated passwords, and of course store your private key

[ZaynDale]

Hackers can purge 1 blockchain node but they cannot forge or hack all of them. Imagine hacking ovet 5,000 Bitcoin blockchain nodes at the same time. Impossible! That's why there are too many investors today for Bitcoin because of its security feature that can guarantee investor's money a good profit.

[KesoNie]

Yes, it is, it can be hacked from your cellphone or personal computer if they can get your password but if the hackers can't get the details with you, they cannot hacked your bitcoin.

Yes it can be hacked why not? In this digital world of internet hackers are been quite alive when they have known something that can be profitable or for any private reasons. So for our own seek only as a user of bitcoin, who has a own account of bitcoin, lets all be responsible for our own seek because we cant control or cannot avoid this circumstances. Whether we like it or not if it would happen that our account will be hacked theres nothing we can do.

[TrumpD]

Wallets and all can be hacked and coins stolen unfortunately, but the blockchain itself is cast iron and data on it cannot be changed after being broadcast. Almost any thing on the inter Web can be hacked if the perpetrators out in enough effort. Always keep that in mind and if possible, keep your coins off-line.

[Souldream]

Yes, it is, it can be hacked from your cellphone or personal computer if they can get your password but if the hackers can't get the details with you, they cannot hacked your bitcoin.

Yes it can be hacked why not? In this digital world of internet hackers are been quite alive when they have known something that can be profitable or for any private reasons. So for our own seek only as a user of bitcoin, who has a own account of bitcoin, lets all be responsible for our own seek because we cant control or cannot avoid this circumstances. Whether we like it or not if it would happen that our account will be hacked theres nothing we can do.

Yes bitcoin can be hacked, my friend already encountered this case. And a much worst we can't even recovered what is already hacked. A very sad thing that could happen to us as a trader because all our hard work that we make to put that account is lost.  So, i get an idea to what happened to my frien that the only thing we can do is to secure pur account, although we can't tell if were gonna be hacked but as long as it didn't happen to us let's be prepare and secure for our own seek.

[donaltrump8]

 I think bitcoin will not be hacked, if you put bitcoin in your blockchain wallet. It is a very high technology for bitcoin security.
 It will be difficult to steal bitcoin .

[weredo911]

It has been 8 years from the date Bitcoin was born. There are no known cases of hacked bitcoin. And it is impossible. But if you store Bitcoin and altcoin in hot wallet, Maybe hackers can attract it.

[Alok Yadav]

There is one type of attack that could affect the bitcoin network: the 51 percent attack, which is widely considered to be bitcoin’s greatest inherent flaw. Because it is decentralized, bitcoin is vulnerable if any one player or cartel gains control of 51 percent of the computing power of all miners. This would allow them to stop transactions and reverse transactions, which would throw the network into chaos. In the past, at least one group has achieved control of 50 percent of the network. However, the more people using bitcoin, the safer it is — and more people are using bitcoin now than ever. It’s difficult to get an accurate count of how many users bitcoin has, but the estimates are in the millions.
Where Bitcoin becomes truly insecure is when other technology starts to get involved. Bitcoin was conceived as a “trustless” system; you don’t have to trust any centralized party in order to use your money, because transactions are facilitated by other members of the network. In reality, bitcoin is too complicated for most people to use without mediators such as apps, wallets, and other digital currency services. The biggest need is for third party exchanges, which are sites where bitcoin is bought and sold for other currencies. All these third party services are only as safe as their own security. Mt. Gox, arguably the most famous example of an exchange going belly up, filed for bankruptcy in early 2014 after around 850,000 bitcoins went missing.
Bitcoin is still largely unregulated, which means your money isn’t insured and there is often no accountability for exchanges. So while bitcoin tech itself remains unhacked, the methods used to collect, buy, and sell remain as potential attack vectors.

[shield132]

I think Bitcoin can not be attacked because Blockchain technology is now growing and no one knows how Bitcoin was created. Only exchanges are attacked and this really does not affect Bitcoin

Sorry for late reply on your post but please can you explain me, even if it happened and bitcoin get hacked, why will only exchangers be attacked and how it won't affect bitcoin? In idea, bitcoin gets hacked so it will affect bitcoin of course, can't understand what you wanted to say when you were posting it. It's like hack bitcointalk but only yobit users will be damaged (sounds very far from logic).
P.S please don't open new thread about supercomputer and it's ability to mine all coin and hack all wallet, forget that. Currently it's not possible to "hack" bitcoin, but virtually everything is possible.

[NelfiNovita]

I think bitcoin can not be hacked because blockchain technology is already developing. which can be hacked is bitcoin personal eg bitcoin yours because the security is not necessarily can be maintained.

[CryR]

hack the people yes, hack the system no.

[NelfiNovita]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

might happen, because if the bitcoin community gets more then easily develop a currency that is resistant to attack or blockchain technology.

[Ayush rana]

Actually bitcoin is made up of a very complicated algorithm. Which means it is very difficult or impossible to hack bitcoin.
But the hackers can hack the wallets which are not giving good security to our accounts.

[corybrackett]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

Yes they can if they got the private key of your wallet, everything gonna be dark for you.

[Heacygg]

How is it possible be? it's technology is a top secret. I remember several spam attacks that led to nothing anyways. But doing real damage? No, it can't be hacked in any scenario

[Majharul Saiif]

Bitcoin is a profitable business. It's price is increasing day by day.In this respect,Bitcoin is secure. I think it is not risky one. It can't be hacked because it's security is so high.

[Ararbermas]

Bitcoin is a profitable business. It's price is increasing day by day.In this respect,Bitcoin is secure. I think it is not risky one. It can't be hacked because it's security is so high.

based on the site i read recently its possible to hack bitcoin such as wallet etc. If you dont secure your important key.  Or the reason which is when you connect to any public wifi or free wifi and you attempt to log in your important account.  for example online wallets acounts or social media accounts and etc.  theres a chance that the owner of wifi can access your personal information without risk. Because Now adays there are some stupid people put some key logger to copy all the information of the person connected to wifi . So i suggest that if want to connect in any public wifi don't forget to forgot the wifi first before you leaving to avoid that issue.

[dg2010]

My answer is no. But if your mean is an online wallet, my answer is yes. There is no way confirm that wallet can't be hacked. therefore, the best way to protect yourself is used offline wallet.

[SiDtHeBeSt]

Bitcoins can be hacked? I don't know about bitcoins but i think your bitcoin wallet can be hacked. There would be alot of skilled hackers out there who would be finding out new ways to hack bitcoin wallets. But you surely can make your bitcoin wallet more protected by using the best wallet out there and thus protecting it from hackers to some extent.

[BlueStackz]

It has been 8 years from the date Bitcoin was born. There are no known cases of hacked bitcoin. And it is impossible. But if you store Bitcoin and altcoin in hot wallet, Maybe hackers can attract it.

Yes bitcoin is providing high security. It is not easy to hack bitcoin. So its quite safe to invest here and wait for the profit patiently and be committed to what we want to do. Seek proper knowledge and be keen about guidance enter some promising project and deal the profit wisely. Then all what result will be a comfortable living.

[Fasdartin]

Since bitcoin is become popular many network security concerns about hackers and bitcoin exchanges have raised serious concerns about storing and transaction digital money in any form. But i think it cannot be hack if we have trusted bitcoin  wallet.

[stompix]

How is it possible be? it's technology is a top secret. I remember several spam attacks that led to nothing anyways. But doing real damage? No, it can't be hacked in any scenario

Top secret?
https://github.com/bitcoin/bitcoin

Check it out. It's so secret every bit of code is public for everyone to see.
Stop posting crap, please.

It has been 8 years from the date Bitcoin was born. There are no known cases of hacked bitcoin. And it is impossible. But if you store Bitcoin and altcoin in hot wallet, Maybe hackers can attract it.

Yes bitcoin is providing high security. It is not easy to hack bitcoin.

No, "not easy" it's not the right word. When we talk about bitcoin we talk about the protocol and that is impossible to hack, mainly because there is nothing to "hack".
The only ones that are getting hacked are the ones that can't protect their wallets or servers.

[Delarock]

Its been a problem since the beginning of time. There will always be criminals out there in this world. Its just a fact of life I am not afraid.

[JimmieA]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

As I know, attacking this forum or similar forum is not difficult for hackers but to attack the wallets to steal btc is very difficult or maybe say that that's impossible. The wallet has a very high security level that can not be undone.  That is also a strength of btc.

[posternat]

I would worry more about your personal PC and its access to your wallets being hacked. There are more and more ways that the scammers get you to download a file or app and then they have all your passwords, keys and what not. That is really the only viable reason to use online wallets, because some of the sites go beyond the key use and use two and three levels of security. New coins every day get this and that person to install the "wallet" and then it is all over.

[iram3130]

Wallets can be hacked and not Bitcoin, but that's why you have keys and pin numbers, to keep your wallet safe and secure. It those are on digital platform then take it out and keep it physical.

[Belkaa]

Recent network security concerns about hackers and bitcoin exchanges have raised serious concerns about storing and transacting digital money in any form.

These concerns are compounded by the fact that no central bank or governmental authority backs the safety or soundness of digital currencies. Unlike fiat currencies like the US dollar, which is printed by the Federal Reserve, bitcoins are minted by complex interactions across a broad global computer network.

Due to the nature of digital mining, bitcoin’s value cannot be manipulated or altered. Bitcoin's value is secured thanks to the cryptographic functions that it employs, and though it could be hacked one day in the future, technology and cryptography experts agree that such an attack is unlikely in the near-term. However, the networks and storage locations where bitcoins are housed and “protected” can be hacked by malevolent forces. Despite assurances by bitcoin storage companies and developers of the currency, bitcoin exchanges can and have been hacked.

Wallets can be hacked and not Bitcoin, but that's why you have keys and pin numbers, to keep your wallet safe and secure. It those are on digital platform then take it out and keep it physical.

That's correct, those wallets only gets hacked when we get reckless and loose our private keys somehow through social engineering or just leaving our computer at risk for some worms to steal information including your keys. It's just a matter of what we can do to protect our bitcoins than what hackers can do to steal them away from us.

[wolfracer]

be discarded. We know that technology is increasing exponentially, bringing as a consequence that in the not too distant future, everything that we know as safe is no longer. However, there is a ample possibility of bitcoin theft, but for reasons beyond to itself, as carelessness by users when transacting
 

[Emerge]

Bitcoin can not be hacked, but you still need to be careful because wallets can be haked. That's why you need 2 FA or private key

[yamortsac]

Bitcoin cannot be hacked as long as your security is tight. No one should know your password except you, never entrust to anybody or give it to anyone. Only you can secure your bitcoin.

[Reid]

Bitcoin can not be hacked, but you still need to be careful because wallets can be haked. That's why you need 2 FA or private key

Correct. Most of the website wallets dont have a private key and it would be best to use one with that kind of service.
2FA is okay but still I would prefer the private key.
Also better to have a offline wallet rather than a website which is probe to scams.

[PancongStreet]

I have never heard bitcoin can be hacked, because it has a reliable and secure system. they have a unique wallet address

[Zinkin]

I think Bitcoin can not be attacked because Blockchain technology is now growing and no one knows how Bitcoin was created. Only exchanges are attacked and this really does not affect Bitcoin

Exactly, I don't understand why people say that Bitcoin can be hacked if the one being hacked is the person. Bitcoin has nothing to partake in this kind of disaster. No matter how many times you've been hacked or scammed, it is at the person's fault alone and not the medium that have been used.

[yanesna3]

The worst hackers of Bitcoin is its forks. These are not cyber criminals, but it clones undermine BTC power and make unstable prices. Many investors start to worry about saving in Bitcoins. 

[Lacocanostra88]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

No, no, no. I try it many times, dosnt works

[mammoniter]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

I wouldn't eliminate the possibility to exploit something in bitcoin system that may cause its security to be breached but with todays technology and computers computing power available it would be almost close to impossible for individual hackers to do it.

[noictib]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

In my opinion here I don't think that we need to redefine the technology of the bitcoin blockchain Because it is already much powerful and encrypted then any another one technology .
Here clearly we can see that why many countries government are against the bitcoin and also why many big banks are against the bitcoin but opposite of that they are looking to devlop own technology of blockchain where they can run fiat currency with high security but I don't think that they can  easily Because they are hating it slots , so we can understand well that bitcoin is already at high level security and no chance to hack bitcoin ever in the future .

[Faroxx]

Theoretically, the bitcoin is very difficult to crack with current technologies. If you consider that the complexity of cracking increases all the time it seems to me that in the future hacking of bitcoin will also be impossible.

[GazorpPozorpec]

The technology of the blockchain is that the more people use bitcoin, the harder it is to crack. At the current level of development of a network hack bitcoin almost impossible.

[Jupeter]

For me the bitcoin accout can be hacked, my friends account here in bitcoin forum is been hacked last 2weeks and he is so sad because he can not recover it because he use invalid email, so my advice is when you will create an account here in this forum is always used a valid email so even the hackers hacked it we can recover it.

[Kita Kita]

Well nothing is impossible for all those hackers, but for me the bitcoin is can't be hacked but the wallet we are using to save our money is can be hackable and  it can be easy to hack if the wallet we are using is not very secured so i have an advice always use a legit and secured wallet and dont ever share your your earnings in your bitcoin wallet so it can avoid to be hack.

[BlockMedx]

The only things with Bitcoin that can be "hacked" are entities that interact with the blockchain i.e. exchanges, wallet apps etc.  So the point of failure is always some 3rd party entity.  Now, the actual blockchain cryptography could theoretically be hacked by some sort of quantum computing mechanism, but we're still a looooong way away from anything like that being possible, and solutions are being worked on currently as well for that eventuality

[Gracie12]

In fact, bitcoin is the world's top hacker developed, of course, bitcoin will be hacked, but bitcoin has a strong calculation and protection mechanisms. So bitcoin is not afraid of the usual hacker attacks, we can rest assured.

[xiaomingdada]

Bitcoin is safe in itself, hackers can not attack bitcoin. But hackers can attack the wallet, so protect your wallet. If you feel insecure, I suggest you use an offline wallet.

[Hypnosis00]

Bitcoin cannot be hacked but the wallet of bitcoin can be hack. Bitcoin wallets particularly the online wallets are not safe to put our money or bitcoin because they are very prone for hackers that can be a reason for them to hack it and get or steal our bitcoins from it so it is best to get an offline wallet to stay safe and out of the radar of the hackers.

[Getcoinsite]

Everything is hackable nothing can deny it.but if we will use the proper security measures hackers will fail on us.just look for all the safety features that suit your computer lappy or gadget.and dont be careless in regards to your wallet.

[Gracie12]

In fact, bitcoin is the world's top hacker developed, of course, bitcoin will be hacked, but bitcoin has a strong calculation and protection mechanisms. So bitcoin is not afraid of the usual hacker attacks, we can rest assured.

[MWesterweele]

No it can never be hacked because in long time there is no one complained about there bitcoin that  was hack. Also because bitcoin is secure when you store it in wallet, just dont share your private key, or personal matters about your bitcoin.

[slashz9]

if the hack to create directly it is not possible. because until now we also do not know how bitcoin was made, but if someone hacking someone else's account it could happen.
as I experienced recently 

[cipher-x_09]

Well, it is possible to our bitcoin wallet because there are a lot of ways hackers can access your bitcoin address and they can easily gain access to your account given that you don't give any appropriate countermeasures for hackers. As for the whole bitcoin if they by the blockchain technology and overrides its system then they can freely manipulate all the transactions in the bitcoin. But as of now it is not possible because the bitcoin technology is protected with a lot of security features which even an expert hacker can find it difficult to access through.

[Kiiti1]

I can't say it's quite complicated

[kittybabe@06]

Yup its possible i have a friend that her bitcoin was hacked she dont have an idea how it happens. But when she visit her bitcoin almost have of them lost.

[rindo]

A Bitcoin hack would cost it´s Market cap to give a small possibility of creating new Bitcoins... That would be the only possiblity to hack it. But on other hand, according to a recent study by Chainalysis, a company analyzing data from Blockchain, about 23% of the Bitcoins already issued may be lost forever. The study represents the first detailed effort to quantify the number of digital currency units that may have had their private keys lost. However, it is impossible to say exactly how many Bitcoins are actually lost and how many are barely saved without recent recorded movement.

[knotnissan]

There is risk of anything Internet generated and "virtual" that is unsafe, or has the potential to be hacked. You have to decide if the risk is worth the reward.

[cluend]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

bitcoin have strong security which make it better than Google, Government, FBI , NASA

I agree that everything can be hacked and, unfortunately, bitcoin doesn't have such a good defense as you say

[Laurayaki]

We've already heard a lot about bitcoin hack history, after that it was often the misuse of people and not bitcoin itself.

[Walrus1]

The blockchain will be hacked. As companies and governments adopt it will be part of the usual quantam computing is already trying and some say it has been done.
 

[reymartH]

Bitcoin is theoretically vulnerable to hacking. Because its code is open source, programmers continuously review it for flaws. This means the underlying protocol is pretty robust.

Bitcoin is theoretically vulnerable to hacking. Because its code is open source, programmers continuously review it for flaws. This means the underlying protocol is pretty robust.

of course the security system used by bitcoin will inevitably continue to update so strong and can not be penetrated by hackers. and I am sure the security system that is provided will still give us a sense of security even if at any time. hope that all bitcoin users still get a sense of security

[tanjiran]

maybe. blockchain is a remarkable system development. KYC has also been developed to control every transaction made using bitcoin. I am sure the digital money security system will continue to increase, so that it will no doubt or no longer be a tool of crime.

[bitfools]

The blockchain will be hacked. As companies and governments adopt it will be part of the usual quantam computing is already trying and some say it has been done.
 

The problem here is that 99% don't have a clue about what it is they're talking about,

IMHO the number of 'programmers' working to 'hack' bitcoin is 10to1 to the number of people just mining the art of 'hacking bitcoin' is a much more interesting problem than just 'mining'.

The 'hacking' of BITCOIN is an industry,

Last month I wrote an entire article here about how to 'hack bitcoin'

It's being done, the 'hack' of NICEHASH in past 24 hours ( $62Million USD) is a classic example aka 'mt-gox', happens all time and its ignored, ignored until its all gone.

I would not worry much, there are 2,000+ BTC clones, and one of them say zencash or monero will gladly fill its place if&when BTC gets easily hacked

Most likely problem is this sodom&gomorah/tower-of-babel problem like we have now 1,000's of blocks, and wallets in a sea of mis-communication, all be ran by common criminals ( nicehash/mt-gox, ... ) and their whores.

***

Problem with 'hacking bitcoin' is no two morons agrees, IMHO 'hacking' means programming, it means typing on  keyboard, thus ALL misdirection of BTC is hacking,

There is wallet snatch&crack, there is keyboard sniffing ( russian porn industry ), there is brute-force private-address ( brainflayer ), there are algo's for all mined coins to go after different dimensions of 'hacking btc', I would suspect a ten volume set of books could be written on the subject, trouble it would be out of date if not completed within a month

For now most interesting of areas of BTC-HACKING IMHO are attacking private keys owned by high-value accounts, that's where the money is, that's where the real work effort goes by the pro's.

Almost all these high-profile rip-offs like mt-gox or nicehash are 'inside jobs', so not 3rd party hacking, but guy in mom's basement, but more likely just a normal in-house 'worker' getting his share before their PONZI collapses.

BLOCKCHAIN technology is here to stay

PRIVACY is probably most important issue, completely ignored by everybody associated with BTC, who clearly just care about MONEY, and don't give a shit about crypto-anarchy.

Satoshi would PUKE on what has become of Bitcoin.

Satoshi is dead or in prison, as dead men tell no tales.

Today 'Bitcoin' is just an amalgamation of morons and criminals, say the recent "BITCOIN GOLD LAUNCH" BTG by Russian/Chinese mafia, that's the essential element of todays BITCOIN WORLD.

[josephpogi]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

The bitcoin is rising do i think thereis no doubt that some hackers doing their best to hack some acccounts but not bitcoin so my advise is just use a trusted wallet and secured to protect your account from them keep safe.

[Hagmonar]

As far as i know bitcoin cannot be hack by anyone bitcoin is invencible and secured. Some other people there acount get hack its because of there email if somebody knows about your email pasword they can already hack you acount.

[kraisee]

no

[TheGodFather]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

Of course it can be hacked. everything that is under digital networks and electronics and programming. It can be hacked and manipulated and worse it can be stolen and you would be left with an empty purse and a very aching heart.

[oaz7t]

Definitely Bitcoin can be hacked. Anything that is on the digital network can be hacked and recently NiceHash, the largest Bitcoin mining marketplace has been hacked which resulted in the theft of more than 4700 Bitcoins worth over $57 million and the stolen bitcoin now is worth $70 million in less than 24 hours, so try to be safe and use low.

[Miles123]

Bitcoin cannot be hacked but some accounts or wallet can be hacked if we don't secure are all passwords. We should be aware of hackers because they are everywhere and wise is the key so that we can't be hack. Bitcoin is the answer in our all needs to sustain us.

[MrCrank]

No, it's impossible.

Although, if will hack sha-256, can possible hack bitcoin.
But no one hack sha256, need find collisions using super computer

[BeGoods]

We've already heard a lot about bitcoin hack history, after that it was often the misuse of people and not bitcoin itself.

Very grateful as long as I use bitcoin for 5 years I have never experienced hacking. yeah I think if somebody gets a bad things like bitcoin hacked. I think it's because of the problem on the users tself. you should add some security patches like authentication and bitcoin wallet support it

[mikel00]

of course not bitcoin cant be hacked because bitcoin is more secure and safe

[pxo.011]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

yes it is.. some of the hacker can do it just simply spying your computer, beware of anonymous emails i am a one of the victim

[Hanako]

In bitcoin we are all anonymous and no one can even know us. Unless we give our personal details or posted it here. Bitcoin is a digital cryptocurrency and can't even hacked at all because there's so many people's protecting it to hacked, but i know therw's a code that needs to know and only satoshi nakamoto know it. So probably there's no one can evem hacked because nakamoto isn't even active and no one knows her

[Bandon]

Bitcoins are a digital bearer asset.  That means that anyone who holds the secret key (a 256 bit random number) controls the bitcoins.  Hacking bitcoin, therefore, typically involves finding out a way to steal a user's secret key through technical means or by social engineering (i.e. fooling them into giving away the key).  To that extent, hacking a user's bitcoin account/wallet is not much different than hacking any other software platform.  The basics are similar.

[Ejanend]

Bitcoin cannot be hacked but some accounts or wallet can be hacked if we don't secure are all passwords. We should be aware of hackers because they are everywhere and wise is the key so that we can't be hack. Bitcoin is the answer in our all needs to sustain us.

For sure it is our responsibility to secure our wallets and not to share our password and key word with anyone.  If you are having fine information and knowledge about bitcoin you will not suffer hacking and will get safe and secure profit. There are a lot of wallets available in market easily you can have it and put all of bitcoin into it to avoid hacking and lose of money.

[ModGirl]

i think it can be, but the question is.
how far can you go ? hahaha
that is to much server nodes, to much computer you will hack, hahaha
whenever the system still growing but not yet done for hacking, its wasting time.
the bitcoin is built by complicated system and will grow that system everytime it need.
so, can you hack it before 60s is up ?
 
if you ask me, i will give up first before you ask 

Feeling very strange when I hear that hacker can hacked Bitcoin. It may be possible for very short period of time. But there are a lots of core developer who are belongs to different countries of the world. They all are showing their expertise in updating the system. So I would be in very rare cases that Bitcoin can be hacked but all the investors feel no worry. Very soon it will be recovered.

[Boov]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

Well, if you observe that some of the hackers always saying is "No system is safe!", and i believe that this is true. And also Yes, Bitcoin is super secured site that an ethical hacker can't hack easily. But i know that many IT experts are always securing the vulnerabilities of a Bitcoin. So that intruders are not allowing to in to this site. I believe that Bitcoin have the low chance of possibility that a Hacker can hack it but There's a high chance that It will be down its server in just a few minute but it will be back again.

[stripykitteh]

Bitcoin can be hacked if there was ever a Hardfork. Technical glitches are usually found in Bitcoin Clients so look into that.

Everything is possible so it is also possible that Bitcoin is hackable. Even if it is impossible, people make it possible. They always find a way at everything. Thus, Bitcoin can be hacked in a matter of time by genuises out there.

Age of quantum computers is coming, they have impossible speed of computing and can decrypt cryptography defense of most cryptocurrencies

[ys fs]

if that's true, then bitcoin threatened by hack hackers who want to make money the easy way and I do not agree with it, so use a stronger account security verification

[rube08]

Your bitcoin wallet can't be hacked, unless you give out your unentrypted wallet.dat file.  If you encrypt your wallet.dat file with a passphrase ( at least one capital letter and a special character), you should be fine. Also, never give out your private keys.  Private keys are for you only and no one else.  Do not fall for email phishing scams that request your private keys.

[bitfools]

Give me your wallet.dat, I will crack it for you in less than two hours, 'jack the ripper' has been doing this stuff 10+ years, and now the rainbow table is up to 50 GB,

Most ppl  use a 'human phrase' for their wallet, unless your using 512 dice rolls to build your phrase sha-key, then I can break your pass, in less than two hours.

This is why so many viruses steal wallet.dat files, because its so easy to crack.

Most of the people here are liars or fools to push this notion that anything on BTC is safe.

Also NSA gov already has a database operational to connect REAL-ID with everybody on earth that holds BTC, which means that the IRS can knock on your door anyday they wish, if your a miner, or you ever bought BTC and didn't report it on your IRS tax return, also FATCA laws require yearly declaration of all currency, and almost everybody who has BTC is already a FELON.

[tengek37]

I think everything that shaped digital I think potentially exposed hack including Bitcoin. a few days ago the news was spread that a user is Bitcoin lost 4 k Bitcoin because his account was hacked.

[bitfools]

I think everything that shaped digital I think potentially exposed hack including Bitcoin. a few days ago the news was spread that a user is Bitcoin lost 4 k Bitcoin because his account was hacked.

I think ever bitfool should spend at least 3 months learning the trade of 'btc hacking', THEN&ONLY THEN will your BTC be secure.

Trouble is 99% of the entire BTC racket is based on non-reality bullshit

Once U know all the tricks of the hacker, then U can make your BTC until then your just putting your trust into the hands of the criminal exchanges, and mining-pools.

These days' it can honestly be said that more money is made 'hacking' BTC than mining, just like the 1920's ppl robbed banks cuz that's where the money is, now hackers rob BTC, cuz that's where the easy money is, and for now, its not even a crime that can be enforced

The nature of BTC since day one has always been 'non-recourse' which to the criminal minded means "GET OUT OF JAIL FREE CARD FOR LIFE"

[jancukiyah]

No, no one can be hack bitcoin. Who knows how the security of bitcoin? For the biggest blockchain, they've the biggest security too. Except it if your question about the wallet, the wallet can be hacked any time. But don't worry, you just should choose the best wallet with the private keys for access it.

[Zero1One0]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

You need a quantum computer and quantum power (e.g. power of the sun) to crack bitcoin.
Technically at this time, this is impossible.

Since, it's impossible to hack that's the reason why the price keeps rising.

There is bit difficult to break the security protocols of bitcoin and if someone knows about the private key of any other person then there may be possibility that the owner told him earlier that’s why he is accessing someone else’s coins, this thing is not termed as the hacking and so far there is no case of hacked bitcoin and all this shows the hard and high standards of security which is securing the huge amount of people from the looters.

[radeone]

Not yet... I am sure that bitcoin-core will solve potential attacks as the technology keeps exponentially changing.

I suggest u google "Large Bitcoin Collider" ... LBC

1,000's of ppl, hackers if u wish, are working on this, and NO, they're not going to go public when they grab somebody's coin, and the guy who gets robbed, will be ignored on this forum like he is a pariah for questioning btc

Impossible to attack 10**77, but not impossible to attack 10**28

It's really just a matter of education, professional cryptography ppl know this shit, laymen buy the bullshit spread on this forum

If 'cracking' was not POSSIBLE the NSA would not be a $100 BILLION/YEAR factory in UTAH, if cracking was not possible, then there would be no NSA, shit SHA-256 (BITCOIN) was created by NSA, they don't make public, that which they don't have master-key

[TIDOVEE]

Definitely bitcoin can be hacked. A lot of bitcoin has even been hacked recently of which I would have been a victim. Those messages sent on slack requesting for etherium private keys has led to the hacking of many's account people complaining bitterly, to avoid your bitcoin from being hacked in your account, be sensitive to those messages you respond to, especially any message requesting for your private key. If revealed, your coin is no more safe.

[TonyMark]

No it cannot be hacked because it is based on the Blockchain Technology! If one wants to hack, he has to hack all the miners computer at one time which is not possible at this time.

[hadveach]

which I know that the bitcoin security system has a hard-to-solve code, so it's hard to hack. and that's not possible.

[Rajamuda]

Bitcoin can't be hacked, but bitcoin's wallet can be hacked.
Although I personally never experienced it, but already many people who has been hacked on their bitcoin's wallet.
It's good we should stay cautious, and use a reliable antivirus, and choose the wallet's web site that is really very safe and trustworthy, can be avoid from hackers.

[bajigur894784]

I think it could be, because Bitcoin is vulnerable to theft if you become a victim of a phishing attack that gives hackers access to the computer or phone where you saved it.

Hackers can create a backdoor by persuading users to visit an infected site, click a link, open an attachment or plug in a USB key and then use a tool called Bitcoin Jacker to search the Bitcoin wallet and transfer its contents over the internet to its own wallet.

[Ingoats]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

I think it is not possible to be hacked due to i strong blockchain technology. Bitciin is already existing for years but there are no reports of cases about hackers. Some will say it is, and it is hard to tell. Big people are investing to Bitcoin and surely even if there's no one who manages it, they will make sure that their wealth won't just be stolen by hackers.

[intoy_victor]

Bitcoin can't be hacked because bitcoin is invulnerable. Bitcoin was discovered long time ago but there is no one could ever hacked bitcoin, I know that many people wants to hack it because they want to get bitcoins in just easy ways but if there is a man that could hacked the bitcoin is surely the richest, smartest and wise guy in the whole world.

[thenameisjay]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

I don't think so. Bitcoins are on a blockchain of millions of computers. It's more powerful than a supercomputer. Bitcoins are well protected from hackers because of this. But of course, the possibility is still imminent since there can be some sort of a virus capable of destroying the blockchain.

[bitfocus]

Bitcoin cannot be hacked but your Bitcoin Wallet can be hacked. There's a difference between Bitcoin and Wallet. Also, your exchange can get hacked, too. So, keep your Bitcoins safe on Paper Wallet or Hardware Wallet.

[thekingall]

I think no one can attack Bitcoin, Bitcoin is anonymous and no one can attack it.

[ardhigalau]

Everyone knows if you want to hack a bitcoin you need to paralyze blockchain first, but that's impossible. Jannagn takes a shortcut to get bitcoin, better invest or join bounty campaign in this forum in order to get bitcoin by doing the task given bounty manager.

Every think can be hacked when its associated with internet and bitcoin is also available on internet so there is a chance of bitcoin to be hacked and in past some countries and also some organization try to end bitcoin from market but unfortunately they were fail and they did not end bitcoin so I’m sure if this time again when someone try to do anything wrong with bitcoin so he will also be defeated by bitcoin because bitcoin know to defend itself.

[MoonHodler]

its one of the hardest systems to hack (today)

and if it does get hacked somehow, it will be evident to all miners, so they can take action about that.

[didoubk]

I do not really if bitcoin can be hacked or not, but i think that at a such stage, the security system is more powerful  than hackers technics m and it must be because many people are saving good quantities of bitcoin and its bad to lose their money.

[ujjwalsethi]

Yes all your bitcoins can be lost as it can be taken if the private key of your wallet is known by someone. So be careful while filling any form or sharing your information with anyone. You can share your public key of the wallet but keep in mind that never share your private key with anyone.

[Alok_Yadav]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

Bitcoin can't be hacked but exchanges can be on which you could have bitcoin that could be lost.

[liktawak]

There had been a lot of bitcoin hacking story scattered over the internet but those people who share their story I think just lack being careful might had log in into a psihing site using their wallet credentials or had carelessly exposed their private keys somewhere haven't heard about hacking done through decrypting pass or something related so far.

[zemb]

Yes, bitcoin can be hacked. If hackers put a key logger on your computer they can transfer all of your bitcoins.If you download any virus or wallet which infected in virus they can hack your bitcoin. 

[Sendibere]

I think bitcoin can not be hack because it's hard to do, what hackers do is take your bitcoin because you give a little gap where you do not give security to your account wallets can be hacked and many users got hacked before and many others will be in the future because wallets security depends on the user himself. no one can be hack bitcoin beacuase they've the biggest security too.

[GuardiollaJosep1259]

There is risk of anything Internet generated and "virtual" that is unsafe, or has the potential to be hacked. You have to decide if the risk is worth the reward.

[Peashooter]

I think bitcoin can not be fi hack because it's hard to do, what hackers do is take your bitcoin because you give a little gap where you do not give security to your account

I absolutely agree to that, bitcoin is can't be hacked by someone or a hacker because it has a security that no one can enter. In addition to that, even a professional hacker can't it because it has a security level. Lastly, just keep your private and password in a safe place so that youe bitcoin will be safe.

[nyong]

no, because the security of bitcoin is very high. so it's hard to get hacked

[Copulative]

Well, it is possible to our bitcoin wallet because there are a lot of ways hackers can access your bitcoin address and they can easily gain access to your account given that you don't give any appropriate countermeasures for hackers. As for the whole bitcoin if they by the blockchain technology and overrides its system then they can freely manipulate all the transactions in the bitcoin. But as of now it is not possible because the bitcoin technology is protected with a lot of security features which even an expert hacker can find it difficult to access through.

It is not possible that anyone can hack bitcoin because bitcoin is not a small or local currency but its an international currency and we can prove that by previous history of bitcoin that still there is no such news came about hacking of bitcoin.

[Daimon88]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

Bitcoin cant be hack but the storage or wallet can, that is why you need to be very careful change your password every month install anti-virus if necessary be careful with the fishing site.

you should be careful changing your password time to time. Also update your anti virus a lot of ways to prevent from hacking. You should use vpn or other secure browser prevent from hacking in case you are using online wallet. If you using wallet offline you should keep track on your password in order to prevent hacking. You should limit your traffic only use secured internet connections not every public connection.

[Vibr56]

Bitcoin can be hacked but it's virtually impossible to do so since you'd have to hack thousands of running computers at the same exact moment. Bitcoin wallets are more likely to be attacked.

[metenjean]

Everything is hackable in my opinion but bitcoin security system might already know the flaws since the 1st time it created, so instead of hacking bitcoin that might be more difficult. Lots of people try other chance to stole your bitcoin by hacking exchanger or wallet that store bitcoin

[cokkapaga]

Bitcoin is can't be hacked, bitcoin is decentralized system. no one can be hacked of bitcoin
but the wallet online and exchanges to store your bitcoin is possible can be hacked.

[TheGreatBangleGouse]

Of course it can be hacked and stolen, especially bit bitcoin "banks"

I really do not understand why people store their bitcoin in banks that can get hacked.

If you want a real foolproof way of avoiding bitcoin hacking then store your bitcoins in "cold storage"

which is a PC or USB that is unconnected to the internet.

[khimer_rangers]

I think bitcoin is very safe because it uses a very sophisticated system, and it's very hard to hack, except the bitcoin owners themselves, who are careless in security.

[blackbutterfly]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

Well is it possible that bitcoin can be hacked because here in this world have a many programmers and not all of the have a good attitude, mostly of them are what we called "hackers" and it is possible that bitcoin can be hacked.

[Bonakid]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

Yeah its possible because there are some bad persons who are greedy and can access because they have skills to do it,unfornately we have nothing to do with them,if we are careless and cannot secure our account hackers can easily get our money.

[Freyya08]

I think its possible that it can be hacked but maybe in wallets, hackers can log in or try to hacked the log in keys so that is why you have to be very careful specially for your private keys. And make sure to change or update your password every month.

[teejayrichard2]

anything is hackable depending on the hacker, that is why huge money is spent yearly by countries to fight cyber crimes and hackers. bitcoin can be hacked but i believe those behind bitcoin are top programmers who work tirelessly to prevent bitcoin hack.

[sarojan9980]

No one can able to hack Bitcoin because Bitcoin has constructed by blockchain technology. Bitcoin is secured.

If we talk about the technology behind bitcoin, i dont think so but if we pertain to individual's holdings then yes. Wallets can be hacked that is why it is your sole responsibility to safeguard it.

[Pesona1]

I have never heard bitcoin hacked directly, but I often hear wallet or exchange hack and pick up bitcoin. I think it is very difficult to hack bitcoin because it has a good security system.

[Xanxus024]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

Yes it is possible, the better things to do is do not let anyone know your private key, do not connect your devices in public places, do not click any suspicious link, then generate or activate your 2f factor for high security.

[Bonakid]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

I think it will never hacked due to its decentralized they can never find our key.And I am not experiencing the hacking of bitcoin but I am hoping it will never happen for some bad persons who wants to do it.So thats why I want the security for bitcoin because there are lots of people who are very intelligent in doing bad things.

yea you are right. It is not possible that bitcoin will be hacked and this is because of strong security and if it was possible that hacker will hacked it till but it will never possible for hacker and this is because of decentralization of BTC.

[hazelcryptocoin]

I believe Bitcoin can not be hacked because blockchain technology is growing and no one knows where it is , the exchange could be hacked but probability is very less..

[Grahambell]

If in my opinion, bitcoin can also be hacked because bitcoin is also related to the internet, I think rarely do bitcoin hackers because bitcoins have excellent security and hacker fees are very expensive.

[btcrut2017]

No, Bitcoin can't be hacked. Block chain technology is so complex that in my opinion can't be hacked. They should do their best to protect the bitcoin holder in order for this digital currency to continue. Who will invest in bitcoin if it is hackable. The future of bitcoin depends on how strong Block chain is.

[megalith07]

Well nothing is outlandish for each one of those hackers yet for me the BTC is can't be hacked yet the wallet we are utilizing to spare our cash is can be hackable and it can be anything but difficult to hack if the wallet we are utilizing isn't exceptionally secured so I have a guidance dependably utilize a genuine and secured wallet and don't ever share your income in your BTC wallet so it can evade to be hack.

[btcmayumana]

If you means by systems, they are still any possibilities even low such as transaction which has not yet pickup by miner would be attacking target. Attacking means that tx can be dropped not take over. Another case are Mt.Gox, this exchanges was been hacked in 2013, many BTC was stolen and it's purely about weak security systems of exchanges not Bitcoin it self. For acct wallet hacked as we talking about hardware or desktop wallet, i think it's very low possibilities.

[mevmike]

As of now i haven't heard of any news that mentions bitcoin being hacked.
losing your coins can only happen if you fail to secure your own wallet.
that is why it is of utmost importance for anyone engage in crytocurrency to learn all necessary fields before making anything than can put their coins at risk.

[ngefek berat]

In my opinion,bitcoin site is very difficult to be hacked because the blockchain system is very fast growing and make the security tighter. But if the business do the transaction there is the possibility of hacking then we must be more careful in doing various trading activities to buy coins every time.

[calvenbtc8926]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

It is not possible that bitcoin can be hacked because many of our hacker that will protect bitcoin as their job for good compensation of Bitcoin.

[randal9]

theoretical - everything can be hacked, but in practice, I doubt that bitcoin faces any danger...people and became attached to it for the reason that it is reliable

[markleal]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

Hi there Major_Troubles! Don’t you worry because you are not getting any trouble in bitcoin. Bitcoin itself, the block chain technology could not possibly be hacked because it is a network or thousand and maybe millions of computers. So hacking will require accessing all those computers that are processing the transactions. What could be hacked is the company that provide a wallet to the users. You could search Mt. Gox hacking and the latest Nice hash hacking incidents. While Mt. Gox is a wallet company and Nice hash s a crypto mining company. Nevertheless, you could store your bitcoins in a physical wallet to prevent the hacking but be sure to keep it in a safe place. 

[Freshmen]

No, Bitcoin can't be hacked. Block chain technology is so complex that in my opinion can't be hacked. They should do their best to protect the bitcoin holder in order for this digital currency to continue. Who will invest in bitcoin if it is hackable. The future of bitcoin depends on how strong Block chain is.

It is very popular among the cyber punks that no system is safe. To err is human. We all know that. Something that is created by humans will definitely include some loopholes or vulnerabilities. True hackers are gifted with an analytical mind.

The can dig up even the slightest details. Plus, any new technology can be exploited more easily as it contains more errors. But no worries. There are always counter measures. We just need to follow them.

[teejayrichard2]

Yes bitcoin can be hacked especially your bitcoin wallet. Nothing is beyond the reach of hackers as they spend lots of time trying to hack into things every now and then that is why lots of money is spent on cyber security year after year

[vaughn125]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

Umm nope, saying that bitcoin can be hacked is like saying that smoke can be kept inside your fists.
If you have heard something about that, you might have misheard it or misread it.
Maybe what you saw was telling a story of a wallet being hacked, private keys being Lost, or forgotten,
clicking phishing links, etc., All due to carelessness by the owners.
Or maybe what you read or heard was an exchange being hacked.  All these are possible and have
happened a lot already, but it can never hapoen to bitcoin.

[Chikitita2004]

Everything can be hacked. Physical money can be robbed so also bitcoin in a wallet. But i think with blockchain it is easier tracked. Everything anf every transaction is transparent of it is discoverable i think who the hackers are.

[Best Dreams]

If in my opinion, bitcoin can also be hacked because bitcoin is also related to the internet, I think rarely do bitcoin hackers because bitcoins have excellent security and hacker fees are very expensive.

Bitcoin is very strong and safe because we know about bitcoin in past bitcoin have already faced a different forks and challenges so it got a lot of experience from market we know that bitcoin is decentralized but I’m sure that it’s one of the strong network where a lot of people they are working there and they are also going to monitor bitcoin because they know that some people can be harmful for bitcoin.

[harbin55]

Like what I said earlier everything in this world deals with the development of technology and all system develop are subject to the threats of hacking.
There are lots of badass person who can do such thing so the company and management of bitcoin hire a expert in IT in order to provide a secured and strong security.

[ropyu1978]

I can not say yes, or not. there are many people who are tempted to hack crypto.
so it will basically always have a pretty risky risk, but for now. wallets and exchange have been greatly tightened to avoid attacks from hackers.

[susuberuang]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

can not seem to, because bitcoin security is very unusual encryption of blockchain is very difficult to solve, for now bitcoin technology that still can not be broken by hackers. they are just trying to create a phishing web similar to blockchain to outwit the victims.

[Qartersa]

While I am a Bitcoin enthusiast, I still do not subscribe to the idea that due to it being heavily encrypted it cannot get hacked. Since it exists online, it can definitely get hacked either because of the system, the expertise of the hacker, or the personal negligence of the account holder. You see, there can be various contributing factors that may lead to Bitcoin accounts getting hacked. Of course these factors are true not only to Bitcoin alone. It can likewise happen to traditional fiat currencies.

[loof99]

Using bitcoin in all means of transaction most especially in payment system will be a great and big help to us.
Through this we can able to enter in a transaction smooth and faster which we do not need to make manual procedures and we can lessen the time and cost allotted for this activity.

[Akash55]

I think its not possible.But also if you give your password to someone they han hacked your wallet.Otherwise it's safe

[Baijit20]

I think bitcoin can not be hacked because Blockchain, the underlying technology behind bitcoin has no history of such attacks.but if you mean bitcoin wallets then ans is yes.

[SameerSony]

It is almost impossible to hack bitcoin because the technology behind bitcoin is very good.

[honeyira]

Everything in the internet can be hacked.  Good thing with the btc is has a unique security which is difficult to hack.

[Ariess]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

I don't know, I hope it will never happen. in a system, all always have weaknesses and protect the server. but so far, bitcoin has no problem, it's just that some hacking happens on wallet and exchange.

[janah]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

Its possible that your bitcoin can be hacked because even blockchain is more growing up it means the hackers are also growing up because the more technology they learn the more they can gained knowledge about hacking. Btw there are two types of hackers the professionals and the moron hackers. The professionals will hacked those who have much money in the wallet and the moron hackers is the one who will hacked every wallet they know.

[shezu007]

I don't think so that bitcoin can be hacked in this era. Because Bitcoin security is very high and there is no such way that anyone can hacked BTC and according to my experience if it was possible to hack BTC then BTC will be hacked still but i think all hacker will have tried their best but they have find no way. BTC is most secure and due to this security big investors are involve here investing their money.

[nikenv2212]

Yes, all could happen, so far some people in a country like south korea have lost their bitcoin. I hope the incident will not happen again, hopefully the future bitcoin technology increasingly difficult to hack

[Denies]

I think not, bitcoin is quite difficult to hack. but if on wallet and exchange I think always have a risk. yes we know many of hacker always eyeing wallets and exchange markets. so we need to be more careful again to overcome something that does not want to happen.

[izanagi narukami]

Yes, all could happen, so far some people in a country like south korea have lost their bitcoin. I hope the incident will not happen again, hopefully the future bitcoin technology increasingly difficult to hack

If this keep happening, I'm afraid that one day Korean government decide to ban bitcoin officially.
I trust bitcoin security still the best so we must more clever than smart hacker recently to prevent hacking accident in the future

[Topaz72]

I think bitcoin can not be hacked because Blockchain, the underlying technology behind bitcoin has no history of such attacks.but if you mean bitcoin wallets then ans is yes.

Bitcoin is a digital currency and hackers also using internet to hack some ting and as far as I know about bitcoin its now very strong because in past a lot of forks and challenges bitcoin have faced and the way bitcoin fight against them I can’t tell you because of only bitcoin defeat them but it reached to many rich countries and now they all are supporting bitcoin because bitcoin is one of the best currency in market and ever one they support bitcoin.

[yvesp110]

I think not, bitcoin is quite difficult to hack. but if on wallet and exchange I think always have a risk. yes we know many of hacker always eyeing wallets and exchange markets. so we need to be more careful again to overcome something that does not want to happen.

If we talk about bitcoin being hacked due to its algorithm or the technology used in its creation, that would be probably not true because it uses one of the strongest and unbreakable algo which is SHA256 its mean that as a Secure Hash Algorithm based upon 32 bytes. Now breaking a hash with such a large space of possible combinations is not practical in reality. If bitcoin is hacked, it can be a fault of the holder or the exchange.

[RakknRoll]

Yes it can be hacked but it is so difficult, because there's too much security in terms of bitcoin and if it is happen it will recover easy and fast.

[BAZZOUKA]

YES
WE CAN HAKED BITCOIN

[pavingyucky]

I say that they try to do so, but good luck to them because Bitcoin has a high security system that bans the third-parties to penetrate their system. That is why users feel very secured in here.

[Mark Sherman]

There are two Bitcoins:

Bitcoin protocol: The technology that makes up the protocol.
Bitcoin blockchain: The most popular implementation of the technology.
The Bitcoin protocol uses cryptographic technology that has not yet been hacked. (If it were hacked, there are much bigger problems to worry about).

The Bitcoin blockchain relies on a network of operators to make sure the blockchain/ledger/database tracking BTC accounts and balances is current and reliable.

What makes the Bitcoin blockchain theoretically reliable is that no single operator can make unilateral changes to the database. To do so would require controlling a majority of the computing power used to validate changes to the database.

[humanCNC]

Bitcoin is digital money, all its activities and transactions are thanks to the internet. Therefore, bitcoin can be attacked. If investors are not careful they may be attacked by bitcoin hackers.

[datodota002]

I'm not say bitcoin can be hacked, bitcoin can be hacked but it will very long time to tbe hacked and maybe that just 1 chain on the blockchain. instead of hacking bitcoin the hackers prefer hacking to get bitcoins. many hackers are hacking into companies and agencies to exploit their server resources to run hidden mining. there are also hackers who hack a third party like an exchanger or wallet app to send bitcoins to their wallet. they do all that because they know that if they try to hack the bitcoin directly it will only waste their time.

[Odlanyer]

Bitcoin can't be hack because its so hard to do, because the concept is based on decentralization  but if bitcoin wallet yes its possible, many others will be in the future because wallets security depends on the user himself, we are the responsible to protect are btc wallet.

[AndreDister]

well, the creator bitkoynov died and she was conceived as an autonomous independent currency so that hardly anyone will be able to intervene in them
 

[enjotan]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

no system can not be hacked. but it is not as easy as turning a palm to hack a bitcoin or an exchange. I am sure, developers such as exchange or wallet developers. has made a lot of security to block incoming attacks.

[zxl912157]

I do not expect that, it is inevitable that bitcoin will attract everyone to commit a crime. including hackers.
even I am reluctant to think bad things.

[lenarichi]

Take, for example, DDoS - attack. The principle of the DDoS action is inseparable from the nature of the "single point of failure" in centralized systems, which allows attackers to break the entire system by attacking one point. Bitcoin is an ideal tool for resistance to DDoS attacks, although at present the fixed block size of 1 MB strangles the network

[Johnyfun]

Bitcoin can't be hacked because bitcoin is invulnerable. Bitcoin was discovered long time ago but there is no one could ever hacked bitcoin, I know that many people wants to hack it because they want to get bitcoins in just easy ways but if there is a man that could hacked the bitcoin is surely the richest, smartest and wise guy in the whole world.

[Aveatrex]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

In theory,to hack the bitcoin network you will need to decrypt/hash every single transaction in the Blockchain,however to do this,you must have a huge computing power.
I have read somewhere that even if all computers in the world team up and try to do this,it would take a very long time.
Keep in mind new daily created transactions too

[congtuan001122asd]

Bitcoin is digital money, every bitcoin deal and store is made possible through the internet. Thus, bitcoin can be attacked by hackers. If the bitcoin user is not careful then they can take all the bitcoin.

[cybersofts]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.
But, is it possible?

No one can hack the bitcoin or the bitcoin network.
The bitcoin was created based on the peer-to-peer technology.
Bitcoin is also secure to the level where no person or computer program that can break it.
Bitcoin was created with strong cryptography and very complex algorithms that runs completely on blockchain.

[Tramle091296]

I think Bitcoin can not be attacked because Blockchain technology is now growing and no one knows how Bitcoin was created. Only exchanges are attacked and this really does not affect Bitcoin

and also before the bitcoin can be hack they need to unlock or the sacurity of a bitcoin wallet. But bitcoin wallet is in the hands of the owner unless they careful about theyre account they cant be hack.

[lacusfish]

Based from the feedbacks of the users, they haven’t experienced any signs of hackers. The only reason they lose money is because of third-parties and frauds.

[veemon34]

nothing is imposible, but i hope fully btc cannot be hacked , because far as i know, btc is the best way to invest our money and the most secure too.

[imyashir]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

blockchain technology is not and hard-backed. if you are afraid of being bitacked by your bitcoin. Avoid storing bitcoins in online wallets and exchangers. It's a good bitcoin wallet that we hold our own private key and you need to handle it firmly and do not let others know you just need to be sure your bitcoin is secured. PAPER WALLET IS A BEST WALLET.

[Sum24]

I do not expect that, it is inevitable that bitcoin will attract everyone to commit a crime. including hackers.
even I am reluctant to think bad things.

There is no doubt that bitcoin is decentralized but I believe there is someone who is going to monitor bitcoin and I’m sure bitcoin will have a main office in some where thousands of people they are working there and they will not allow any hacker to hack bitcoin because bitcoin is the only source to earn a lot of money from it and for that bitcoin will struggle more to keep it safe because it’s also good for bitcoin to be safe.

[Manchumichael]

I don't know bitcoin is the only source to earn a lot of money, but i agree that some team is working on Bitcoin security. if they do not work then how they can improve this bitcoin technology. But they are not showing their identity that's it. Hacking bitcoin is not easy, but people can hack if you not secure your system with internet security.

[Krispin47]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

Bitcoin can be hacked if the system is not too secured we need to upgrade our system, more secrets to more secured

[jason.romano]

No, it hasn’t happened before and the tough security of the blockchain ensures that it cannot be hacked. With the technology used in it, I highly doubt it ever happening.

[daduremi]

some say that there is no security system that is really safe
but I think bitcoin exceptions, is not the case of pisihing or theft of the contents of the wallet only happen several times only and that too long does not happen again, we just need to be careful, especially when saving your private key not to be lost or in the know of others

[aljun107]

No. It will not gonna reach its current status if its secuirity can be hacked. Of course there lots of security codes that is needed for a hacker to have it. And there is really no records of bitcoin being hacked by someone.

[Lpim01]

The unique creation of bitcoin is the thing that could never be crack, it's system really impress everyone that make our coins into a 100% secured.
Some people get hack just because of their own negligence and also they are sharing their account into others.

[Wexnident]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

I think it is. Bitcoin still is an online platform so it is really possible. But one thing is for sure, it won't be easy. Bitcoin is becoming more successful but still there's no reports of direct hacking cases. So we can relax. Also big investors earnes benefit from Bitcoin so they won't allow such thing to happen.

[robbietobby]

I think experts had built extra built-in in order not to hacked or steal information or in  a  way or another. If talking anout bitcoin in your wallet its yes, because you are liable in any information you had been submitting on each spreadsheet during signature campaign.

[endut15]

I think experts had built extra built-in in order not to hacked or steal information or in  a  way or another. If talking anout bitcoin in your wallet its yes, because you are liable in any information you had been submitting on each spreadsheet during signature campaign.

even though the experts have built whatever it is, the hacker name still exists, because the hacker is very clever, so we are advised to be more careful in maintaining our wallets as well as other transactions, because everything is our own responsibility.

[sheryl26]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

Yes it is possible to hack the bitcoins wallet because here in the computer world the world of technology nothing is impossible but for now i do not have some hacking issues in my wallet it supposed that the wallet that i use have a lot of security purposes. So lucky for me i didn't experienced that hacker thing. I am not sure if there are a persons that are a victim of a hacking and lose a lot all of their money. But bitcoins is still unhackable the main bitcons cannot be hacked.

[lesya-ya]

If a hacker is able to determine some of your non-cryptocurrency-related personal information, he or she may be able to infiltrate your transactions in that space regardless. All bitcoin investors are advised to take proper precautions in order to best protect their holdings.

[cryptojoe]

Anything can be hacked. You know I'm right.

[zais]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

Investors and Bitcoin new users plunge into the world of cryptocurrency will be very easy to fear if they hear of anyone losing Bitcoin for being hacked. Please note beforehand that Bitcoin can be lost if not keeping it well,

[edengolo]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

I don't think Bitcoin can be hacked.
The blockchain is a very sophisticated, and I think it is impossible to hack it.

[Liquid01]

not possible, how could it be because of its P2P transaction system is no one knows it. and there is a problem in my country that the hospital data can not be opened because in the hack and people who nge hack ask for a fee with bitcoin it's obvious they can not hack bitcoin

[De Suga09]

No, it isn't.

This is really possible. Bitcoin is programmed anonymously so it is possible that it can also be hacked anonymously. Blockchain technology is also a complex system. It is better to be more vigilant especially with setting passwords.

[klim75]

If you don't take precautions, it is possible. You should keep your wallet and private keys safe.
Bitcoin still is an online platform so it is really possible. But I think, it won't be easy. Bitcoin is becoming more successful but still there's no reports of direct hacking cases.

[Extrago]

I do not expect that, it is inevitable that bitcoin will attract everyone to commit a crime. including hackers.
even I am reluctant to think bad things.

So far this technology hasn't been hacked in any case, as far as I know, perhaps there are different wallets. Other than that, there's nothing to be afraid of so far. I personally am not afriad that they'll hack it.

[cx_primo]

Im thinking if Bitcoin. Bitcoin himself is not bur the wallet or altcoins maybe.

[skillzdunk2]

I think that access already exists or will soon appear to all the wallets in the world

[lindatang]

the technology is great ，willnever

[siddu67]

No way.Bitcoin can not be hacked.Bitcoin privacy is very strong.No hacker can hack bitcoin.But if you do any foolish work like showing your password to others or giving a weak/simple/same password then you can be trapped into hackers trap.So be careful in giving your password.

[dhianeji]

I think there is no such thing impossible in this world since all things are deals with the usage of technology. There is chance that it may happen but the company of bitcoin provides a high security to prevent this threats and protect the interest of their investor free from all kinds of risk

[MLM2016]

In my opinion, bitcoine can not be attacked and it is difficult to penetrate the blockchain

[mr.bean865]

In my opinion, bitcoine can not be attacked and it is difficult to penetrate the blockchain

Its difficult but not impossible to hack the valets due to advancement in hacking day by day so Its better to use two or three valets to minimize the loss that unfortunately one gets hacked you still have most of your bitcoins in the remaining valets

[yourialfa]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

I think it could happen due to user negligence. But until now I have never felt the loss of my bitcoin. Honestly I say this is very safe. Try to think positively that this is something safe

[Jexjatto]

I know its possible that bitcoin can be hacked, but it will be difficult, but not impossible, that is why you have to make sure your security password is strong, and beware of phishing sites,.. Plus when you see a deal that is too good to be true, be sure to double check.

[freetokens]

Bitcoin cant be hacked only wallets we no 2fa are hacked mostly

[Dudeperfect]

Considering the current computing power I don't think that anything like brute force attack is possible to access the private keys but yes quantum computing will have that power but then we will have a better security for the Bitcoin network so there is no reason to worry about it as far as the core technology is concerned. However, if someone is holding his funds anywhere other than under his own control then there is always a risk associated with it because you never know what kind of precautions are being taken by the (your) bitcoin holder.

[semenencoa]

What does it mean "hacked"? Bitcoin is decentralized cryptocurrency it is impossible to hack. The chain of bitcoin its information is on every pc which is part of the system.

[Thymoty]

for now, there is no news about Blockchain in an attack, Bitcoin with its Blockchain technology cannot be attacked because Blockchain is like a Bank ledger, and this is not an ordinary technology
Blockchain cannot be manipulated because its cryptographer is very secure
so only Wallet and Exchange can be attacked by Hacker

[freshm4ker]

If you say about blockchain and bitcoin. I think it's impossible to hack. Bitcoin can also be decentralized that it has its own server or bitcoin itself is a server and every second it turns it into an encrypted key so that hackers will have difficulty in overcoming it.

[jak3]

Bitcoin is being based on cryptography which makes it harder to crack the network but that doesn't mean it is impossible to crack it. So let's suppose a hacker has a supercomputer and he tries to crack a private key with it then it will take very long time but let's assume it takes around 3 years of constant cracking so it is not guaranteed that even if the hacker is successfully able to crack a private key and whether the user is going to keep his balance on that address for over 3 years. And the blockchain network is based on the chain system where if anyone tries to modify A block then all the previous blocks will become invalid and miners have to mine the whole network from the start. So this is how secure it is.

[Falgorn]

The algorithms for computing the hash function of the SHA-256 and ECDSA standards are considered to be those that can not be cracked on current computer power. The advent of high-performance quantum computers will increase the risk of hacking these functions. In this case, the hash function Bitcoin can be replaced by a more complex one.

[severaldetails]

Really hacking bitcoin in order to create blocks by purpose, that is not possible at the moment. If it would be, somebody would have done so and the bitcoin would be worthless. What the future holds, nobody can tell. I don't even think of the quantum computers that are often mentioned. I am more thinking of artificial intelligence. If the programs get smarter over time maybe one of them will find find a way.

[dayem708]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

Nope, you can not hack bitcoin but you can bitcoin holders' coin in a different way. but mainly you can not hack bitcoin.

[bitcoinorcash]

I think that bitcoin cannot hacked because its already have a strong security when it comes bitcoin and the blockchain are growing too, so we dont need to worry about those hacker man. The man who created bitcoin are so great developer so i believe that no one can attacked the bitcoin forum for transaction.

[Pasicam]

I don't think so, but if you talked about bitcoin wallet i think yess. but bitcoin can't be hack because blockchain technology is now growing and no one knows how bitcoin was created.

[SergeYak]

It's can't be hacked because of difficult hashing algoritm sha256 and series of blocks that can't be hacked until you didn't decipher past blocks. And you will never got enough hashing power.

[CryptoJoshua]

Theoretically, yes. However, I don't think that this would ever be possible. I would be more concerned about whether or not crypto wallets could be hacked since this has been done before and could happen again.

[Lester Cole]

Yes, but it is very unlikely, difficult and expensive - it depends also on type of the network:

permisionless (public blockchain) - it is extremely hard, it requires to take control over most of nodes (almost impossible), but some big countries may be able to do it… - question of cost effectiveness
permissioned (private or consortium blockchain) - it depends on the security of the private/consortium network, it is easier because there is much less nodes to hack and they are easier to track

[Leo Parrish]

Yes but so far it has never happened.

When it will happen, bitcoin will die…

Quantum technology would be something to consider, while the SHA-1 encryption technology has been recently hacked… But not yet the blockchain.

Because it has been able to pass over 10 years without any hacks, it looks like the basics are very well set. But I believe that in technology, everything is possible, it’s a question of time and speed. Quantum is, on paper, able to hack the blockchain but it has to be effective very quickly because it will have to hack the million of computers (on and offline) which contain the blockchain copy. That’s maybe the real difficulty to perform the hack.

Even if you hack 999.999 computers, if only one is still working with a copy of the blockchain (let’s assume it’s an offline one), then you can retrieve everything from the start of the bitcoin, and copy/paste the information very quickly through the network.

So I don’t think we should think that it’s not hackable. It’s a wrong statement.

jm

Don’t forget Nakamoto: nobody knows him, nobody care now. But if he is somewhere and still alive, he’s able to know what to do to scam the network, make some dollars and leave the blockchain as part of the prehistory…

[Milo Hill]

Blockchain stores information across a network of personal computers permanently which distributes the information decentralizing the network. In a decentralized system, there are numerous computers that try to update the ledger, a collection of financial accounts that records every transaction which is ever breathing. To add a block of transactions to the chains, each person maintaining the ledger solves a math problem created by the cryptographic hash function which takes input of any size and creates an output of the fixed size. What makes Blockchain hack proof is the millions of users of Blockchain. They make it difficult for anyone to corrupt the network. Each block has a timestamp and a link to the previous block forming a chronological chain reinforced through cryptography ensuring the records cannot be altered by others. Due to the transactions needing multiple parties’ authorization before acceptance, Blockchain has a high degree of trust value

[DoublerHunter]

Bitcoin cannot be hacked because of its encryption that is end to end which is very powerful for the hackers to hack. Bitcoin is one of the best cryptocurrencies which have a great amount of security that is enough for the users of bitcoin to feel safe and be comfortable, i think that bitcoin's security is one of the most powerful thing in the internet so there is no need to worry for getting hacked.

[automaticmoney]

Bitcoin cant be hacked it is unhackable and no one can cheat bitcoin every code is unique transaction

[stellgod]

What does it mean "hacked"? Bitcoin is decentralized cryptocurrency it is impossible to hack. The chain of bitcoin its information is on every pc which is part of the system.

You can’t say this is impossible. Anything that is formed or developed regarding tough security concerns, they are more available for the hackers to try on it. Like if my house is digitalized then it is not that much vulnerable to thief rather the white house in Washington. Why it is so, because that is more sensitive and potential place than my ordinary house. So bitcoins are more secure, hence more vulnerable to attacks.

[romeo111]

Yes it is possible to hack because we keep our balance in wallet and wallet can be hacked if wallet can hacked, bitcoin also be hacked .

[zeingrind777]

however, hackers will keep looking for ways that they can benefit by taking other people's assets. ranging from web pishing to hacking the system's DNS. to avoid hacker attacks we must be careful in storing bitcoin, and always make sure that the web we use is not pishing.

[Geemy]

From my point of view it is difficult to violate the Bitquin because it is going through about 20 stages to get from the sender to the recipient but it can happen if the 20 violations were breached.

[Visin]

From my point of view it is difficult to violate the Bitquin because it is going through about 20 stages to get from the sender to the recipient but it can happen if the 20 violations were breached.

If there was a secret code to break Bitcoin that wasn't published then that person could damage Bitcoin.

[Viellefox1025]

In my understanding Blockhain makes bitcoin transaction an open ledger to all. A transaction to be approved all the ledgers must agree. so even f you can hack one ledger when you introduce it to the network it, the network will not approve it because it doesn't agrees with the other ledgers.

[albertcrypto110]

Bitcoin can not be attacked If you talk about bitcoin wallets answer is yes .unnless you give out your unentrypted wallet.dat file.  If you encrypt your wallet.dat file with a passphrase ( at least one capital letter and a special character), you should be fine. Also, never give out your private keys.  Private keys are for you only and no one else.  Do not fall for email phishing scams that request your private keys.

[piter66]

In my understanding Blockhain makes bitcoin transaction an open ledger to all. A transaction to be approved all the ledgers must agree. so even f you can hack one ledger when you introduce it to the network it, the network will not approve it because it doesn't agrees with the other ledgers.

In the event that you mean hacking wallets, at that point yes, wallets can be hacked and numerous clients got hacked previously and numerous others will be later on in light of the fact that wallets security relies upon the client himself. However, in the event that you mean hacking the Bitcoin as a running system, I surmise that will be hard if certainly feasible in light of the fact that the idea depends on decentralization and with more clients getting to the system the security winds up more grounded and more grounded.

[Marcus Kelly]

Hacking bitcoin would require a quantum computer, and we don’t have any of those yet. If you did have a quantum computer, you could not only steal other people’s bitcoins (and those which have been lost forever) but you could also produce blocks super fast to enable double spending attacks.

[Milo Hill]

Any hack would probably involve generating fake transactions, but since they are fake, they wouldn’t generate a solvable hash, so miners would spot them immediately, and plenty of people have tried and failed.

You can hack into a bank, but you can’t hack a blockchain.

[Moses Short]

There's a wrong concept in your question. The Bitcoin actually can't be hacked, it's too hard and difficult; what hackers do is put a trojan in some junk mail which the user open, steal all the info about the wallet (address, password, etc) and transfer to 2 or 4 accounts in order to lose tracks.

This is something very common and usually the targets are people who have a big amount of BTC in one account.

[Hallmader]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

I am afraid it might not be possible at all. The progress in the online world is a double-edged sword because it does not only mean that the security of sites and other online innovations have developed, it also means the progress of hackers and their capabilities. For all we know, the online world is actually an everlasting battle between hackers and the people who maintain various online systems. But it is unfortunate that there are times when the hackers are ahead a few steps.

[carlisle1]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

bitcoin is safer than any online money has ever made.the technology behind this are really great as it cant be hacked or even get near into blockchain.the only problem which i see is when the coins are transferred into your wallet or storage,this is the time that bitcoin becomes vulnerable to hackers and scammers that if you dont keep it safe it can be took out from you,since more and more computer experts are in this community

[baby222]

Theoretically bitcoin can not be hacked. I don't see how someone could crack it with all this new technology of bitcoin. I am not afraid to be hacked.

[Daboy_Lyle]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

Bitcoin can't be hacked, but the BITCOIN WALLET is hackable. You can hack wallets by it's private key. That's why I use hardware wallet to avoid wallet being hacked. You can also use 2FA which is best to privately secure your wallet.

[ivakar]

Bitcoin can not be hacked because of its encryption.
It has a great amount of security that is enough for the users of bitcoin to feel safe.
But your wallet can be hacked.

[faredjaber]

If you mean hacking wallets, then yes, wallets can be hacked and many users got hacked before and many others will be in the future because wallets security depends on the user himself. But if you mean hacking the Bitcoin as a running network, I think that will be hard if not impossible because the concept is based on decentralization and with more users accessing the network the security becomes stronger and stronger.

[CryptoWorld87]

No bitcoin cannot be hack. Some other people who realy dont know about bitcoin and they saying that bitcoin was hackable them they alwasy wrong about that. Bitcoin itself is not a hackable and no one can hack bitcoin except they are hacking the email who use to log in the wallet that use by the owner of this bitcoin. This is the only way to hack bitcoin but this is not bitcoin itself you hack the email only not bitcoin.

[marjoree]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

Bitcoin cannot be hacked, but the account or wallet online where all of your bitcoins or other alternative coins are placed is the one that can be hacked. The online world has a a shield to protect all the wallets. The wallet where all our crypto coins are in, are protected by primary keys (composed of random numbers and letters) that only the owner can have it. Imagine, how secured our accounts.

[babarian]

Until now I believe that bitcoin is not easy to hack because blockchain technology is very sophisticated and far more likely to be hacked

[Raja_Salman]

Hacking can happen if we are careless in storing our assets. even the exchanger was in my opinion still not entirely safe because many exchangers are also stolen by hackers

[Ariess]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

there is nothing really safe in the world of the internet. all potentially hacked. as in real life, criminals will never disappear on this earth as long as the opportunity is always there. so you do not have to worry too much, you just need to protect your computer as safe as possible, the rest you let the wallet and exchange developers to protect their servers.

[avoxosuccesful]

I think Bitcoin can not be attacked because Blockchain technology is now growing and no one knows how Bitcoin was created. Only exchanges are attacked and this really does not affect Bitcoin,and this only happens when you predispose your wallet pvk cause long as they can get access too your gmail/yahoo or any?then they can get intoo your wallet also.just gotta be careful  

[shezu007]

IMPOSSIBLE, i mean that it is impossible to hack bitcoin in life and remember if this was possible then all hacker are setting for hacking money sites they will hack it before some years. But there is no possibility to hack bitcoin. We have seen various news about hacker which have tried to hack wallet etc. But they was not success in that mission. Bitcoin security is the main focus of bitcoin forum.

[Ciremik]

If somebody will get 51% of hashrate then technologically also possible. You can also learn about all bitcoin weaknesses from http://en.bitcoinwiki.org/Bitcoin_weaknesses

I saw about this discussion on youtube that it might happen when bitcoin miner double spends the money and they started make another transaction then trying to confirm it - but however I believe this could be prevented if payment recipient makes sure the transaction gets confirmed more than 6 times.  

[bernashka]

Hacking a wallet may not be possible. But social engineering has not been canceled yet, and it consumes much less resources with a much more predictable result.

[Glydel1999]

Yes the company of bitcoin can be hacked. It is the external factors or threats that can affect their performance. In order to prevent this they provide a high security just to ensure that the system is free from hackers.

[kabelpeggek]

bitcoin can never be hacked, because bitcoin has a blockchain system
and there has never been a case where someone lost their bitcoin, except in exchange
hackers prefer to steal on the exchange where bitcoin exchange

[burdagol12345]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

Bitcoin is secure and can never been hacked easily because its has a strong defense system against hacker so why should some people doubt in the cryptocurrency credibility in terms of defense system.we already know that investing of bitcoin is  have a risk but if we talk about security in terms of investment and hacking system,digital currency is no.1 in the rank ,because its protect a different kind of coin and they want to defend there honor.

[MNtrio]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

I believe that bitcoin well be not attack the security of bitcoin is high and theirs no blueprint on it. I believe that there's no possible to attack the bitcoin it's top one in cryptocurrency so they have a higher security on. I think they will attack at our wallet because our token is inside on it.

[CryptoBalds]

Bitcoin is powered by a peer-to-peer ledger and the blockchain is a public ledger that is used to verify and record these transaction so it's impossible to get hacked by anyone and because of they can't change any value or transaction that is being saved into the ledger so its impossible for bitcoin to be hacked. But the address can be phished so we better watch out for the phishing site out there cause it can easily get our address private keys.

[Akosibatman]

No, i dont think bitcoin can be hacked by any greatest hacker in the world. It is almost impossible to hack bitcoin, because you will need to find the private key for a certain wallet address, which is very long and consist of alphanumeric upper and lower case. The problem only in bitcoin is it is more vulnerable on scam or phishing sites. Many criminals do this crimes thatwhy we should study and read a lot of information before engaging in this community.

[Jaya912]

for now, there is no news about Blockchain in an attack, Bitcoin with its Blockchain technology cannot be attacked because Blockchain is like a Bank ledger, and this is not an ordinary technology
Blockchain cannot be manipulated because its cryptographer is very secure
so only Wallet and Exchange can be attacked by Hacker

Yap thats true. So we dont need to be worry about bitcoin itself.
We need to be worry about wallet. How to secure our wallet from unrsponsible hacker.

[mickeybuddy27]

Hacking can happen if we are careless in storing our assets. even the exchanger was in my opinion still not entirely safe because many exchangers are also stolen by hackers

I agree. If the wallet is not being monitored daily you will realize and see that it is not safe anymore and no money to be found. Many hackers are active to get earning in wrong way, add more security for the account that will be hard to them to enter. Do not save account on the untrusted sites that will be done to find victims for them to scammed.

[microwave]

Bitcoin will not be hacked by any one, only the scammers will be, how? by just copying the concept of bitcoin and create the site just like this. So in that case we need to be aware because that is not impossible to happen. So let's go back to the word hacked, I believe that bitcoin will secure and cannot be hacked by any one  because bitcoin will exist so many years ago and until now there is no issues about hacking wit it. So in that case I believed that it cannot be hacked.

[rosanoe]

Bitcoin cant be hacked and it is absolutely secure.

[kikoy999]

bitcoin can not block you if you do not share information with people who are not familiar with and people you can not trust because if you have multiple scammer accounts so you have to be careful and do not just deal with transactions with people you are not you should only legit your transaction.

[nyong]

i think no, because the security of bitcoin is very good and difficult to penetrate except on wallet address

[CoinNo1]

If you have researched deeply about blockchain technology, you will believe in that it is impossible to hack a coin or a token because of its decentralize feature.

[yokai21]

yes bitcoin is a bit because the scams are spread in the philippines but it can be prevented from hacking your bitcoin if you do not share information with people you do not know and can not trust because they are my planners who plan to scam you should have your bitcoin early and you will not tell anyone even your cousins ​​for scam prevention.

[garen21]

yes many scammers in bitcoin but avoid it if you avoid sharing information about bitcoin with people you do not know and you can not trust should you share information with your real and legitimate people for you can not scam.

[joshua05]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

It can be, if you'll be careless. You can be hacked, but talking about bitcoins stands in security its impossible to think about it, many millionaires have trusted their money, why would bitcoins's reliable source risk it? BUt in your hands, its your obligations to think and to work for your bitcoins hack-age.

[Derizo]

It's possible to steal bitcoins from a market or a wallet, but you can't hack it. Hacking is not possible due to the blockchain technology, which is now actively integrated into other projects. Even governmental ones.

[Aaarono]

Only the people that are not taking enough safety measures can be hacked. But Bitcoin can't! After all it uses the most innovative technology of all times.

[Dr.Osh]

It's possible to steal bitcoins from a market or a wallet, but you can't hack it. Hacking is not possible due to the blockchain technology, which is now actively integrated into other projects. Even governmental ones.

actually has many cases, or the incidence of bitcoin theft, from the wallet or market. You may have to find this information on the internet. and I've also experienced it, I think a lot of great hackers out there who can steal bitcoin.

[nandamo]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

I guess not, due to highly develop and still growing Blockchain (btc) Technology, Btc is secure. Though exchange are attacked yet didn't affect BTC.

[MrCrank]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

Bitcoin can be hacked = SHA-256 can be hacked
This can't do it.. If SHA-256 will be hacked then will be hacked all systems

[syarifudin]

I never thought if bitcoin can be hacked, but if alamata wallet that we use to save bitcoin may be to hack, because alamata that we use not necessarily safe may be address of purse that we are not necessarily safe goods time address that we use already loose and can be in by the hackers.

[buiduc]

I don’t think btc can be hacked, if btc was hacked so crypto will be hard to survive
Hope btc will be never hacked

[Falgorn]

I think the potential threats of hacking bitcoins exist and they are real. In total, I single out three main threats to the security of Bitcoin:
An error in the system code that leads to vulnerability.
Hacking of private keys.
The seizure of control of the blockade (the so-called "51% attack").

[hrvalino]

Bitcoin cannot be hacked because of Blockchain technology which is decentralized. Not unless someone will hack you to steal the information of your wallet.

[boddy.dy]

Everything that is in the web can be hacked. The difficulty of being hacked is the big difference now. There are a lot of good hackers out there which are just waiting for their client to say which website will be take down. In this modern word we can say that hackers are one of the bad job that are in demand because they are being paid well. In the case of bitcoin, we can say that this can be hacked but surely even the best hackers will took a very hard time in taking this down. 

[asdnguyenthanhtin]

You can only steal bitcoin. If you want to hack bitcoin, you have to control more than 50% of the coin mining in the world. That is almost impossible

[Astermony]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

Yes it can be hacked if you dont keep it in a secured software or simply just allowed another person to open your wallet.Be responsible enough because once you lost it you will lost it forever.

[AfanasjevIur]

Hello. Bitcoin is a currency that can be seen in the interest, and I get it that it is connected with the Internet everything can be hacked! And since the currency is not official, then there will probably be no punishment for theft (sad ...

[adekunleoyediran]

i dont think its platform can be hacked as a trading section

[lani123lani]

Bitcoin can not be hacked but bitcoin can be stolen by hackers because you are less secure in storing your bitcoin because there are fraudulent hackers who can steal it.

[Serdaldal]

Bitcoin always suffers this attack, but Bitcoin has not received any defeats. On the contrary, Bitcoin always protects its own financial situation, no matter how much it attacks, so it is impossible for Bitcoin to have a blow or a sinking due to these attacks.

[websoftwareengineer]

yes many scammers in bitcoin but avoid it if you avoid sharing information about bitcoin with people you do not know and you can not trust should you share information with your real and legitimate people for you can not scam.

There are a lot of scammers in the market because they did not want to earn coins in a hard way and even in this forum, there are threads that users are posting fake links in order to steal other peoples coin so we should always be careful on the sites we are logging our wallets in order for us to avoid being hacked.

[Danielavgonz]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

I think it isn't

[Alexis.Nick]

Bitcoin will never be hacked and can’t be hacked. On the first place the user of bitcoins are the one who are good in the process in the internet. Surely they will not invest or spend money and time here if they think that this things can be hacked or even worst may be gone because of hackers. And as the users of this increases also many people were concern with the security of their investment and what surely did by bitcoin is to intensify its security for the people who have bad intentions with it. That is way they are doing things to improve the process flow of the bitcoin which will help us to feel secure with our bitcoins.

[Roboabhishek]

I don't think bitcoin can be hacked because it is very secured cryptocurrency.

[bayibufo]

No.No One Can Hacked Bitcoin

[bitbunnny]

If you mean on Bitcoin itself and blockchain technology it can't be hacked. So as a system inin whole is safe.
But wallets that contain Bitcoin could be hacked and this could be huge security issue. But as I said, this can happen localy if you don't protect yoursel properly and take all necessary security meassures or use inadequate wallet.

[KingOfWinterfell01]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

Wallets and websites can be hacked, but I really doubt bitcoins itself can be hacked. Wallets and trading websites claim they're safe but in truth, anything is hackable and everything can be accessed given enough tools and time. Bitcoin Wallets are no exceptions.

[Sasuke102001]

See whatever news we keep hearing about scams related to bitcoin it isn't the bitcoins that are getting hacked it is the ICOs which are getting hacked which in turn causes the attackers to transfer the bitcoins to them from the ICOs. I don't know whether blockchain can be hacked or not, most probably I guess blockchain cannot be hacked or attacked that easily.

[Mazda17]

I think Bitcoin can not be attacked because Blockchain technology is now growing and no one knows how Bitcoin was created. Only exchanges are attacked and this really does not affect Bitcoin

Good thinking and I agree a bit with your opinion.
I think about the bitcoin hack bit believing because there is news spread if the hacker is there there is even someone who says "if anyone can stop hackers then I will give the fund of 150 dollars as a guarantee" means there is news circulating and also us as bitcoin users should be more careful again.

[sumangs]

Applying the concept of blockchain, it is almost impossible to hack since all holders of bitcoin in public ledger are too many for hacker to bypass it. It takes a very large computing device to hack bitcoin and blockchain and the device I said earlier doesn't exist yet so it is safe for today. Try reading about blockchain to get more info about it why it is hard to be breached.

[Wolfwar]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

  If we talk about the coin itself bitcoin, then I do not think that it can be hacked. If we talk about the blocking system, this is also not possible, since all those who work with bitcoin and generally crypto participate in it. So bitcoin is safe in any situation.

[adpinbr]

It depends.The success of bitcoin as a currency may attract hackers to learn how the blockchain technology works and how they can manage to hack bitcoin accounts.Also, some accounts are connected to their email address and cell phone numbers. If hackers know how to hack their accounts then they might have the chance to authenticate transactions. This is just a reminder. The word bitcoin is already risky in terms of investment and it is still risky because of security but life is a risk itself.We take risks and if we lose or win then fate must have something to do with it.

[EmJay]

It's possible to steal bitcoins from a market or a wallet, but you can't hack it. Hacking is not possible due to the blockchain technology, which is now actively integrated into other projects. Even governmental ones.

Yeah i agree. Bitcoin can't be hacked. But it can be stollen in the wallet it depends on how you take care of your password or private key. So inorder to be safe keep your private key in a safe place .

[emsjvh]

It is theoretically possible to hack everything. If someone came up with a security system, then someone knows the keys to its destruction. There are no 100% safe things in the world.

[emsjvh]

Applying the concept of blockchain, it is almost impossible to hack since all holders of bitcoin in public ledger are too many for hacker to bypass it. It takes a very large computing device to hack bitcoin and blockchain and the device I said earlier doesn't exist yet so it is safe for today. Try reading about blockchain to get more info about it why it is hard to be breached.

Sooner or later there will be somewhere such a "smart guy" who will find a way to crack a safe chain. Maybe he is already preparing attacks and we do not know about it.

[Ish_Rox]

Actually, Bitcoin can't hack anyone directly.But using spam mail messages or hack exchange account or any other trick  you can hack btc wallets.

[JohnWick_Bitcoin]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

Programmers can always enhance the system and tighten up the security but there will be always a way for a smart hacker to penetrate the application or website. Maybe we can expect a lot more about the stronger security in our wallets and other coin holders but still we should always expect that it is penetrateable since it is working online.

[Crystacool]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

I don't think it's possible. Bitcoin won't be hacked. What you need to worry about is keeping your bitcoin wallet safe, and a hacker may invade your wallet. Take care of your secret key.

[bambino]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

Bitcoin is the main crypto currency but it,s not as anonimous as we want and bcz of this disadvantage were created more safety currencies like Neo or Dash.

[Raffaele Rago]

No It’s quite impossible to hack bitcoin because the technology bitcoin use. It’s very good technology.

[Odlanyer]

I think no because the creator of bitcoin secured it to make sure all the user are use bitcoin well but the account like wallets or website of user that using bitcoin  maybe can me hacked because many evil hacker spreading in bitcoin world and they do all they want even though it is not appropriate and everything can accessed by anyone.

[orarider]

I think that can not happen. Because bitcoin has high security. The bitcoin market is expanding around the world. Bitcoin managers must do everything possible to prevent thieves. I am very confident when investing in bitcoin.

[liamnorthcoins]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

Bitcoin has never been hacked from it's nine (9) years of existence. The Block Chain technology is impenetrible. This is actually one of the best high lights about bitcoin- It is very secured. Usually the hacking happens in the 2nd networks/party or when one goes to other transaction of transfering funds in the investors wallet.

So It is very important to be extra careful in doing transactions of your wallets because it is where the the hacking happens usually. I suggest one must go to legit networks or 2nd parties in making of transactions of your wallets.

Well, generally unless the entire technology will be gone then there is nothing to be worry about of his/her bitcoin investment.

[ocim128]

bitcoin currency can't be hacked but someone who has bitcoin can be hacked

[JRoa]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

Your bitcoins can be hacked by other people if you will store it in ordinary bitcoin wallet. I prefer to you to use trusted bitcoin wallet for you to secure your bitcoins. Trusted bitcoin wallets are using high security so you can ensure that your bitcoins are safe.

[Habakkuk]

That's one of the disadvantages of the Bitcoin even in cryptos world generally, the fear of loosing coin is one of the key chasing away millions of people to join the cryptos world,
I hope for a new era about this.

[aztvn123]

Its possible that your bitcoin can be hacked but  bitcoin is quite difficult to hack. we are the responsible to protect our wallet

[randulakoralage961007]

It is nearly impossible to hack the Bitcoin network and steal Bitcoins. If you want to hack bitcoin wallet or something you will need to find the private key for a particular public address. For that case, the possibilities are zero.

[cokkapaga]

for 10 years, bitcoin has not yet been hacked. and let's hope it doesn't happen.

its never happen. Bitcoin is cannot be hacked.
The blockchain technology is can't be hacked because basid on decentralized and no the center server. No one can control blockchain and hacked it.

[noelanora99]

So yeah like they said, with the Blockchain technology it's hardly likely to ever gonna happen. though not absolute, it still give us a relatively high security assurance.

And with it's trend that is running, I'm pretty sure that  security issues we'll even be lesser.

[Nyenyepogi]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

i can say yes 100 percent because i am a vicitim of scam like phsiing site so be careful by clicking some sites because one wrong move your money will loss or some icos is scam so dont invest iff you dont know what is coin that you wantt o invest so its more good to buy in some exchanger like bittrex binance just pick a good cryptocurrency aso you will get more money.

[Klintiv]

there is a possibility that bitcoin will be hacked in the future. in the meantime, for 10 years, no one was able to crack bitcoin

[TheSmo]

The theft of bitcoins has now become commonplace and no longer causes such interest as a couple of years ago. The amounts of stolen bitcoins are already measured in hundreds of millions of dollars. Attacks hackers were exchanged bitcoin, major miners, owners of a large number of bitcoins. Not to mention the Internet services, which were originally created to steal bitcoin. In other words, hacking bitcoin is not such a difficult task.

[Gadhoh]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

will definitely be hacked, whose name a network can be hacked, including bitcoin or one bitcoin user account that already has a lot of bitcoins, the security must be properly guarded, and we should be more pleasing if in fact our account is hit by a hack usually ask for a huge reward so our account can come back

[decano]

Bitcoin can't be hacked because bitcoin is invulnerable. Bitcoin was discovered long time ago but there is no one could ever hacked bitcoin, I know that many people wants to hack it because they want to get bitcoins in just easy ways.

[jjbanks994]

Definitely not. I wouldn't worry about the tech itself, but more so the users lol. Lots of margin for error when you buy it and store it along with custodianship.

[Addywealth]

well, anything is possible. we cant explain who controls bitcoin an how its been managed in as much we do not have answers to this question then the system can be manipulated,  Bitcoin needs to be control by central bank for safety precaution. most times our exchange sites were hacked and we coulnt do anything to it.

[heisenberg0000]

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

Nope it isn't. This is because of the block chain technology and the algorithm that bitcoin posses. So in order to hack and duplicate a bitcoin would be totally taxing. I can remember an article I came across where is mention that in order to duplicate 1 bitcoin would cost you more than the current price of bitcoin. And during that time bitcoin was priced around 10000 USD.

[xxToaDxx]

In the event that you simply mean hacking wallets, at that time affirmative, wallets may be hacked and various purchasers got hacked antecedently and various others are afterward in light-weight of the actual fact that wallets security depends upon the shopper himself. However, within the event that you simply mean hacking the Bitcoin as a running system, I surmise that may be laborious if definitely possible in light-weight of the actual fact that the thought depends on decentralization and with additional purchasers reaching to the system the safety finishes up additional grounded and additional grounded.

It can happen if you have Bitcoin balance in your wallet and key or privatkey that we have unintentionally spread, and also now many mulao hackers who have their own way to hack the account or wallet that we have, therefore we must save the key or privatkey and also it's good we duplicate the privatkey.

[Rosilito]

Yes there is a possibility especially bitcoin is decentralized means there are no specific people managing it. Well, also bitcoin runs through our technology and hackers also work through it so bitcoin could be hacked by hackers. Well, if you have the daily monitoring habits with it you could lessen the possibility of it getting hacked or if you have a safe wallet to stored it.

I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it.  I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.

But, is it possible?

Yes it is possible to hack the bitcoins wallet because here in the computer world the world of technology nothing is impossible but for now i do not have some hacking issues in my wallet it supposed that the wallet that i use have a lot of security purposes. So lucky for me i didn't experienced that hacker thing. I am not sure if there are a persons that are a victim of a hacking and lose a lot all of their money. But bitcoins is still unhackable the main bitcons cannot be hacked.

I think nobody can hack bitcoins, Since block chain using highly security and secure from attacking. Bitcoin doesn't exist physical nor can be controlled. But wallets can be hacked by many tricks. A hacker can send a file to his victim to steal his password. So to be more secure you should buy hardware wallets and even then be careful with their private keys too.

[meritbygrace]

Yes there is a possibility,Bitcoin in particular has seen a huge surge in popularity recently.A bitcoin mining service was hacked to the tune of $64 million some time ago.lets guide our key with jealously.

[Kocret02]

It's possible to steal bitcoins from a market or a wallet, but you can't hack it. Hacking is not possible due to the blockchain technology, which is now actively integrated into other projects. Even governmental ones.

bitcoin hacking will be very difficult because it is protected by high funding, hackers can only steal bitcoin from exchange or market available or from the wallet of the participants.

[anana ris]

Blockchain, the underlying technology behind bitcoin has no history of such attacks, although it has been spammed before causing the network to clogged down a little. And with regards to bitcoin wallet, its your own responsibility to protect it against hackers, like having strong passwords, 2FA and secure your private keys. I hope you can research first before posting here because it looks like you don't have a clue what bitcoin/blockchain is

[cizatext]

Bitcoin is very hard to be hacked because of it high security technology that never allow a third party involvement and if there is any case of hack in bitcoin if you check very well the user might have open up some secret details such as private keys to the hacker or even your email being hacked into and from there they have access to your account.

Bitcoin itself cannot be hacked because it is built on the Blockchain, and as we all know the blockchain is an open ledger which is distributed and discentralized,  that means everyone and anyone own the system.  What am saying is that, for the Blockchain to be hacked,  all the individual node running around the world has to be hacked at once before any block can be altered,  this is more or less impossible.  According to my explanation above you should understand that the Blockchain cannot be hacked

[multimix]

If you say about blockchain and bitcoin. I think it's impossible to hack. Bitcoin can also be decentralized that it has its own server or bitcoin itself is a server and every second it turns it into an encrypted key so that hackers will have difficulty in overcoming it.

I think we can split into two case:
- Bitcoin works: Absolutely impossible to attack because of blockchain technology is effective and technology is developing on a modern.
- Personal Bitcoin: Sometimes it can be attacked with security implications. This happens depending on the individual user wallets. They need to secure their wallets with strong passwords and can somehow back them up so they are not lost. It's best to keep your hardware.

Agree. Maybe the right one is stolen instead hacked. Blockchain was created to prevent unwanted access to database,
and it is irreversible. Making it is almost impossible to hacked or something like that.

[harobaru]

bitcoin can never hacked because its information is not at one place. its information is distributed in many places.

[Suffoc8]

Bitcoin cant be hack because it is only a currency, a cryptocurrency, but instead your account can be. For an example is when you share your passwords and accounts to other people then probably they can open your account and hack it.

[amwer]

It is almost impossible to steal Bitcoin Networks Hack and Bitcoins. You need to look for private keys for a specific public address. The possibilities are unlimited. A group of Bitcoin Networks is still working on a project of the power supply company to find a private key.

[1C6fV5DtakfKANLJ8GUV7hCaA]

It would require 10 times much power of the existing hash power of Bitcoin's mining network or more. Simply put, it's impossible. Bitcoin was built for security. It cannot be hacked. The only thing that can be hacked is the human brain. So be careful with your coins as you might fall into a dark gloomy trap.

Hacking bitcoin will be a very difficult task and will requires much effort to get pass through blockchain. This method seems to be not efficient and also not practical because it will be expensive to do. So I think hackers will lose interest to hack bitcoin since the security is heavily tight. Also, I suggest to all to beware of the links that you click and the emails you received to prevent hackers from fishing to your computers.

[Jerical13]

very unlikely.bitcoin is considered one of the most reliable currencies,then why should it be hacked at all? don't see much of a case

[ikiscream]

I think it's not true bitcoin can not be hacked, except your hacked bitcoin storage place,

[andylowe]

I think it's not true bitcoin can not be hacked, except your hacked bitcoin storage place,

Bitcoin can be hacked by someone. Yes, it can be. Traitor is all over and if ever one of the traitor is the that will hacked bitcoin then it can be because bitcoin is for all. So if ever it hacked by someone then other people will learn on how to hacked bitcoin too. Yes, only bitcoin storage place can be hacked so it means no one can do it except for the creator and other members of this, not other people.

[freshm4ker]

Everyone knows if you want to hack the bitcoin, you should also be able to block blockchain first, but it is not possible. Do not take shortcuts to get bitcoin or better invest or join a gift campaign in this forum to get bitcoin pieces by doing the assigned tasks from the manager who rewards the participants.

[Kikir leutik]

There is often a misconception about theft and security hacking that occur in different places of exchange and business. Although these things are unfortunate, none of them involve Bitcoin being hijacked, nor does it mean there is a weakness in Bitcoin. Just as a bank robbery does not mean the dollar has been weakened or polluted. However, good security practices and security solutions are required to provide better protection for users' money security, and to reduce the risk of theft and loss. In recent years, security systems have grown rapidly, such as wallet encryption, wallet offline, hardware wallets, and multiple signature transactions.

[Btcepoy11]

Bitcoin connot be hacked by anyone, bitcoin is safest and secured when it comes in security. However the privite key of the bitcoin users can be hacked if they are not properly protecting there privite key.

[vnck25]

What do you mean by "hacking" Bitcoins? It's a cryptocurrency it cannot be hacked. The thing that can be hacked is the wallets where one keeps the cryptocurrencies. If you have a very weak password or keep the private key in an unsecured, public area then someone can steal your cryptocurrencies. If you mean by someone "creating" bitcoins to inject into the market that is external to the limited quota of 21 million bitcoins, that simply that cannot be done, because to my understanding there is no consensus if you just do it by yourself. This is one of the powers of cryptocurrencies. The guy or group invented cryptocurrencies are simply awesome, that's what I have to say...

[CryPtoEnGanGe]

no no. It can't be hacked. Bitcoin is one of the hardest things to get hacked

[Keeminakar]

All cases of bitcoin theft that I know of were due to incorrect storage organization. And if you really take care of it, then your investment is not in danger. I really believe that.

[bitvelk]

If in 10 years of existence of bitcoin there were no weaknesses in its safety revealed, then we can trust it.

[saffira]

I dont experience it yet. Like the wallet that I am currently using, it is really secured I think because it requires personal information with proof of identification. The only risk is when you forgot your identification number or password. Compare to other such as ethereum, security is tight when it comes to bitcoin.

[jhenz20]

It is impossible, bitcoin cannot be hacked because it is the safest and secure currency that has a full of security. A possible thing that can be hacked is your wallets when you did not secure your private key.Everybody knows that if they want to hacked the bitcoin, They should also be able to blocked the blockchain first, but it is not possible to do that.

[Jcabudx]

Bitcoin can't be hacked but your account can be. The security here in bitcointalk is not much secure in my opinion only. Nothing is safe in the internet world. There are many hackers out there that are trying to catch all the data of every people so that they can hack each account. But in other side maybe yes? Bitcoin can be hack, but bitcoin is still upgrading and updating so there is less chance that it can be hacked.

It is possible, I think  every transaction and website is hackable.
