Bitcoin Forum

Consider the value of bitcoin,it has made exchanges prime targets for hacking, and thus has made hacks there quite lucrative..
I mean the anonymity and irrevocability associated with bitcoin transactions means that the money lost is also irrecoverable, CMIIW..

I believe you are wrong in here, and that is because while the hacks can happen, it doesn't reveal the identify of the people who got hacked at all. At best you may know what city they are in because of an IP address, but how are you supposed to ascertain their physical location? Only the exchange would know that, and unless they hacked your account and you were verified this simply can't happen.

Hacking an exchange account should not affect a personal account of investors with the exchange. I'm thinking the exchange would still have the record of amount of coins owned by an investor, except they also want to be fraudulent because in actual sense, it is money that was stolen and not record.

It doesn't feel like that! Its still hackable no matter what you do. I mean what if you are storing the private keys somewhere on your hardware and one day you go online with public internet and someone just grabs the private keys from your hardware stuff, then it becomes vulnerable to hacking. Its simple fact that anything that is digital it can be hacked.

I mean there is also theory which says that bitcoin wallet hacking with the help of supercomputer will take almost 35 years to get hacked but it is still hackable right? Its all about how you judge the hacking concept. With some time and efforts anything can be intruded into.

Also with some careless attitude we can compromise our hardware wallet and software wallets too. Thats what I think if considered all the facts.

Nothing basically is safe from being hacked. And bitcoin is no exception to it. Actually its popularity and the value it holds makes it more prone to hacking and hijacking.
Lots of bitcoins worth huge money gets hacked time and again.
In August 2016, bitfinix announced that bitcoins worth $77 million was hacked. Similar hacks have  happened   in the past. The only thing different with bitcoin is that who was hacked and who hacked is not known here. All that we get to know is the adress from where the btc vanishes, unless one willingly admits of being hacked.

Certainly the security levels have gone up in recent times but individual secirity should be taken credible in assuring a secure wallet or a system. We cannot simply depend on the blockchain to secure our holdings.

the question you put in the subject has nothing to do with what you are saying here! when an exchange is getting hacked it just means the exchange security was not good enough. it is the same as you walking in the street and getting mugged, that doesn't mean the whole world is an unsafe place, it just means you walked into an unsafe neighborhood and were careless.

as for bitcoin itself, nothing is 100% immune ever. but it is enough to know that for 9 years thousands of hackers from around the world have been trying to hack bitcoin and probably even more people have been working on the same cryptography that bitcoin uses and also more have been working on bitcoin itself.

Bitcoin is not immune to hacking. We should keep in mind that all online activities or websites are hackable. This also applies to your bank account if you have enabled net banking. In fact a friend of mine( who is a security researcher) found a way to transfer money from one bank account to another using the official website of a leading bank in my country. The bank officials simply got the bug patched and told my friend not to mention this anywhere. Same way there are security loopholes on all bitcoin exchanges as well.

It's far easier to hack an exchange or business that holds bitcoin than it is to hack a private key. When you say "is bitcoin immune from hacking" but then you talk about exchanges being targets, you're not talking about the same thing. Bitcoin is considered virtually impossible to hack with current technology (future technology is another question) because the private keys are secure enough that current resources couldn't be mustered to crack the cipher that makes it secure. Hacking an exchange is something else, and it probably far easier because there are multiple fail points and the bitcoins held inside an exchange are only as the weakest fail point. But that's not compromising bitcoin itself, just a central point where there happens to be a lot of bitcoins.

That is not true. In fact, since the blockchain is public, you should be able to track stolen coins. I've even heard that the US is planning on doing something even more serious. The same way there is a list sanctions stating the name of people and organizations (normally criminals) that it's illegal to make transactions with, they are apparently planning on adding addresses there, and then track those addresses and it would be illegal to make transactions with those addresses.

I agree with you, centralized exchanges are definitely the main target for hackers these days, but what I'm trying to say is that bitcoin is not that anonymous, and it's not that easy to spend stolen coins.

Well bitcoin is unhackable atleast till today's date but who news in future with quantum computers coming it might not be unhackable as its is now.

The other thing is users/exchanges gets attacked and hacked due to their loopholes in the security. And bitcoin being anonymous you can't track the user that is right.

Generally if the hacks on the exchange platform is mainly to gain tokens the hacker might not see the names associated with the accounts and therefore not be able to trace it to you.

Yes.. but it is impossible to get hacked if you really protect your private keys.

Most of the exchanges who get hacked, are those who get "artificially" hacked, if you know what i mean with all this..

It is possible to hack an exchange. its possible that traders accounts can be hacked. Its highly possible that an exchange can loss a lot of coins and money to scammers, no matter how secured they are. This fraudster are always on the way for new exchanges and try every possible means to steal coins. They are always on the look out for new technology that will break exchange websites by any means so don't think that they can't. Secure your coins.

Suffice it to say, its very common for people to cite how credit card networks utilize about 10% of the electrical consumption of bitcoin miners, globally. While credit cards utilize less electricity, they are also compromised millions of times more often than bitcoin, with millions of accounts and numbers bought and sold on illegal carding forums.

There are certain trade offs involved. Bitcoin for the most part is secure. It functions effectively and safely as a trust less financial system. Although the security measures utilized on the trust end of the spectrum have been known to fail at times. We see this with Mt. Gox and other exchanges not being able to properly secure things. Likewise with a high percentage of ICOs claiming breaches via phishing. Statistically, its been said that more than 80% of all business with an internet presence will be compromised at one time or another. And so the numbers and statistics are definitely in favor of electronic attackers rather than those whose job it is to secure things.   :)

For the most part bitcoin has proved itself solid against hacking and fraud but with trust based systems the human element tends to creep into the equation which often results in system misconfigurations, zero day attacks and a crop of other issues which can cause even stable and uncompromisable systems to be breached.

in the thread title you are actually asking 2 questions and they have 2 answers!

Is it true that bitcoin immune from hacking & fraud ??
Yes it is true that BTC immune from being hacked. You have to understand
the basics of the Bitcoin Blockchain, here are some snippets from the whitepaper

"4. Proof-of-Work
-snip-
For our timestamp network, we implement the proof-of-work by incrementing a nonce in the
block until a value is found that gives the block's hash the required zero bits.   Once the CPU
effort   has   been   expended   to   make   it   satisfy   the   proof-of-work,   the   block   cannot   be   changed
without  redoing  the   work.    As   later   blocks   are  chained   after  it,   the  work  to  change  the  block
would include redoing all the blocks after it."

This is virtually impossible at the moment and may always remain impossible
because as the hacker is trying to hack a particular block the chain is moving
forward, so the hacker has to enter at a block, change it and try and overtake
the correct chain, that would take more computing power than all the "honest nodes"

"5. Network
-snip-
Nodes   always   consider   the   longest   chain   to   be   the   correct   one   and   will   keep   working   on
extending it.   -snip-"

Is it true that bitcoin immune from hacking & fraud ??
Yes and no, fraud comes about from insecure wallets and is a result of human error.
it is also from scams people exact on others.

It is not every time Exchange got hacked but also sometimes exchanges stole all the BTC and declare it a hacking act. It can be a fraud also so better to be beware. Keep your funds only on well-reputated exchanges. Also, don't keep big amounts on one single exchange. Either keep it in a private key wallet or distribute it to various exchanges.

The operation of BTC cannot be reversed, as long as it is turned out, it will be difficult to find it!

But you can find the transfer record through the record of blockchain!

The police are looking for the block chain technology to lock the criminal behavior on the Internet!

I guess bitcoin is called immune to fraud because every transaction is public so that everyone can see where a bitcoin is going after it was mined. The same things happen when bitcoins are stolen, you can track every single transaction but still you cannot find the person who did that because the transactions are anonymous.

Speaking of hacking bitcoin,that's not true because we saw a lot of incidents where big exchangers were hacked and thousands of bitcoins were stolen from their wallets so it is obviously that bitcoin can actually be hacked, not directly though the blockchain but through different wallets that people are using.

I don't think its free from hacked and fraud, I must saidntgat for now the security of the bitcoin wallet is pretty solid, but the hackers also get smarter and there are a lot of way to hack something, so far there  are still no case of hacking from the wallet but there are cases of hackers attacking exchanges, so I don't think bitcoin is immune from hacking but it certainly difficult to hack bitcoin for now

It's not that it's immune to hacking and fraud, it's that no one has been able to hack into bitcoin yet. The keyword in that entire sentence is YET, there could be a time where a fatal flaw is found and it could screw the entire marketplace (given it would probably have a fix with a soft fork put out quickly and wouldn't hurt people) but this is the risk that we all take in using a currency which is backed by coding.

So it's not immune, just no problems yet.

For now bitcoin can be said to be immune from hacking but in the future I bet someone will find a way to hack the entire network as nothing is unhackable, people just haven't tried hard enough yet to hack it. Your wallets on the other hand are very hackable now if you do not properly protect yourwallet.

Its not impossible per se but the amount of computing power it would take is mind boggling and it would be more profitable to mine the currency its self. I suppose that wouldn't stop bad actors but the sheer cpu power needed makes it all but impossible...for now

Short answer on your question would be that nothing is impossible.
Just think, if pentagon was hacked, which I bet had the greatest security, then why isn't it possible for bitcoin too?
Imagine you have book closed with security and you can't open it by your hands alone but with tools you can.
Everything has it's weak point and there doesn't exist anything that can't be beaten by another different thing.

Bitcoin is highly developerd and guarded, but nevertheless, as one famous hacker said - the most vulnerable chain in every system is a human

Every technology has its vulnerability and that is normal if the team behind the exchanges or any blockchain core has doing nothing to improve the security of its system. That’s why the better the management and cooperation with the team of security experts and programmers the popular the site is.

99.9% safe as long as they’re is no lapses in security protocols and each member will participate in reporting bugs if experienced it.

if you are talking  about the blockchain technology  then  yes it is so far immune    but if you are talking about the exchanges  well that is something else 

almost all the news about BTC  hacks  talk about  hackers stole the hot wallet in exchanges or simply hacked users accounts   and  that is not  the same as saying  hacking BTC 

since the last one will require a super powerful pc that is impossible to make  in order to hack  the btc block  and lets say for example  change a transaction   

that is why it is a great technology + many other great futures   

Yeah is not immune but maybe hackers do not have a way to be able to hack bitcoin yet. the risk of hacking someday will certainly exist because we are in the Internet network and based on coding but we know that bitcoin development is not running in place. ahead the security system of bitcoin of course will be the better

Exchanger always hacker prime target because sometimes they have vulnerable security could breach. Better safe storing our bitcoin on our bitcoin wallet and keep our private key safe. Beside that always aware on suspicious link that sent on our email because sometimes is phising link

That is one of the risks of bitcoin and if you want to use this currency then you need to accept the fact that if you are hacked or scammed you will never see that money again, I know that people will need to get used to this new way of doing things, people are too used to be protected by banks if they screw up but in bitcoin there is no place for screw ups.

I think Bitcoin is not immune to hacking. online activities and websites is hackable.

usually hack is due to our own carelessness. therefore we must be preventive to keep our funds from hackers. one example do not let us wrong web address even though one letter only, better at bookmark our wallet address

I am not sure about this because bitcoin difficult to be hacked but if someone has a high-skills in programming maybe he can hack the account but of course, he needs to break the private keys. but if in the exchanges, I think it depends on how to secure the site to prevent the attackers and how good the support system and the IT team will protect their sites from the hacker. I guess that every exchange will secure their sites so their member can trade will safety.

That is true where the money lost can not be recovered, so hacking is very small chance, I mean I think if you lose your money it is because your mistake like login in phishing site or give private key to other people, that should only you know and it's hard at hacking or being hacked.

Every technology has a flaw that can be exploited from it, Bitcoin technology is not exempted from this, For many years bitcoin hacking attempt is always present but the team behind bitcoin is always fixing every loophole that can be found in this technology. Bitcoin has proof of work which cannot easy to hack or exploit but we don't know yet if one-day bitcoin hacking attempt will be a success. Hacking will occur if the private key is stolen from individuals and fraud will be present if there is a pyramiding scheme that uses bitcoin.

That's why you should never ever store your coins on an exchange.

Bitcoin itself is extremely safe, but if you are entrusting other people to keep your funds like on an exchange, it's no different to traditional banking anymore. All you need to do is to keep your private keys safe, and your coins are safe.

And again, fraud can be easily mitigated by common sense. The irreversible nature of BTC definitely makes BTC payments the payment of choice for scammers to receive.

But apart from these risks which are really not even related to bitcoin itself, bitcoin is backed by numbers, and it's extremely improbable that anyone will find a private key collision, as long as you keep your wallet secure.

Since we cannot control these fraudulent activities and all these hackers, it would be best for us as traders to not store our coins in some exchanges or if ever you store them make it sure that you place like a 2fa authenticator so no one would be able to access them but you yourself only. There are no technologies that are perfect as of this point and one way or another, these hackers will find a way to get some sort of reward for themselves so let's just think a couple of steps forward before these guys and be very careful too.

I will say 50% safe and 50% unsafe, the internet world is just us that will make our secret system happen. We will be safe if we keep all our assets, passwords and more carefully. But if not careful and keep secret documents not carefully then we will lose our assets easily.

Cryptocurrency is an asset for hackers, they will be more flexible to find targets and get targets. Our security system is just self, there is no law governing that hackers who stealing cryptocurrency assets will be criminalized. Because during this time the government (which prohibits bitcoin) will be off hand against the losses suffered by the community.

If you're talking about breaking the "chain" or editing it, it's almost impossible. Unless you happen know how to infiltrate the majority of the nodes then yes. Hacking in btc comes from hacking private companies that exchange btc. They're much easier targets than the actual blockchain.

No matter how safe it is, as long as there are people, it can be revealed that all technology is invented by man, and human nature is unpredictable.

Anyone can open a wallet with a secret key.

You don't keep your keys, and the scammers get your keys through a centralized platform or a simple trick.

The exchange was stolen by hackers for various reasons.

Bitcoin security from hackers and frauds will not happen if we as the holder are more careful and use all the existing security facilities in each of the wallets used. The internet can not guarantee the security of an asset let alone crypto. there is always a gap for the hackers on the internet but it can be minimized with us do not store a username and password in the cloud, we better store the data offline and before we enter the data to access the wallet used for assets we make sure the web is not web phishing.

All that really depends on ourselves because when we can secure the account that we have well then we will get a good sense of comfort. Data security in the digital world is now a very vulnerable thing and must be considered because with it we can avoid the action of hacking and data theft, security is a really important thing because it can trigger the future that we will achieve.

I think the most susceptible target and area of hacking is the owner of bitcoins, as long as our transactions and connectivity
are safe and secure incidents such as hacking can be lessen or avoided. We should all be careful and practice safe protocols
when transacting and accessing accounts at certain areas and places. But we don't know for sure, since hackers today are
very prolific and very good at getting what they want. I think as an extra precautionary, we should also know how to store
and move carefully our investments and money online. Carelessness and recklessness are the very vulnerabilities hackers are
keen on spotting on and exploited in most cases.

I agree. It boils down on how we are going to secure our account so that hackers will not be able to get a hold of our private keys and password. There one good example that everyone should look at.

That dude was hacked while doing live streaming.

Even if Bitcoin was immune to hacking or fraud, the wallets definitely aren't. If you accidentally end up leaking your private keys, you would end up with no tokens in your wallet. You must have heard the story of a guy who had millions of bitcoins in his wallet but had lost his private keys and ended up with nothing.

But, a user can keep himself secure by not clicking on suspicious link which might attempt to steal his private keys. Being cautious and aware are the only ingredients required to make your investments hack proof.

That's true this forum practice fromt he very beginning to separate the ersonal and business life of the workers and rhis made this more unique currency,cause your identity will remain anonymous to the people who you might not good in terms with we should be grateful for that although if the certain person was a scammer we cannot find him anymore since the personal information regarding that person is not given and requirement during the making of the account.

I think bitcoin is safe, bitcoin isnot hackable. your wallet is immune from hacker. In my opinion.

Digital currency is online based marketing.There are no physical money.Online based marketing have some advantage and disadvantages also.Last year in December   7 billion crores of money stolen by hackers.In 2016 it happed also.So I think to prevent fraud &hacking btc should increase its security system.

I am not hacker and I don't know how they do it! Anyway one thing I assured death is certain but the time of death is uncertain. I mean hackers can revive the long time deleted data. They can manipulate us without knowing. It seems applicable for them the quote that says; slowly but surely. I don't know how brilliant they are. Seems they are so genius in terms of manipulating censors, processors, and anything that requires power and energy that base on input and output facts.

Of course it is not immune from hacking. Everything can be hacked even airplanes and governments. However, hacking requires high skills because it is not easy at all. There are many hackers out there who stole bitcoins from many people, and even if you have good security, the penetration can be done. That is why you should keep an eye on your wallet and must have as many wallets as you can in case you get stolen, you will still have other wallets.

That 0.01% are for the vulnerability , hackers can't resist to see millions dollar stored in an exchange indeed and the operator aware already about that matters , they have anticipated it but things didn't goes as planned sometimes , so yeah nothing you can do when it got hacked in the end.
But I see a scheme where a new strange exchange planned to go exit scam by pretend got hacked , everyone should be careful to choose an exchange .

In short the Bitcoin system is free from hacks and fraud, but personally we can get hacked despite avoiding fraud as well. Hacks will only happen if we are careless too, most times they can be avoided granted security setup was done in a proper manner.

With blockchain technology I hope bitcoin can be immune and protected from hackers and fraud. But hakcher certainly will not stay silent, therefore we must remain vigilant and keep our private key not to be stolen

One of bitcoins aspect is anonymity so i think if their is some hacking incident i think it will be really hard to trace your loss, so i think it is irrecoverable but bitcoin itself cannot be hacked, but the bitcoin stored in our wallet or whatever storage can be hacked, just be careful and make sure to keep your private key safe.

I think all comes in websites or internets may prone into hackble and fraud, unless if bitcoin is strictly have thier security that no one can hack i think members or people that with in the group will secured and felt nothing to worry about.

it must be too scary to know this kind of hacking thing, let us just hope that even hackers are trying to hack bitcoin, bitcoin should develop its security too, with all that money, every hackers are trying to figure it out. the best thing is the algorithm of bitcoin system, it is anonymous. where will they find from millions of wallets are to be hacked and whom account has millions worth of money. scratch your head and give up. 

All can be hacked easily, nothing is impossible for hackers, they can hack your computer and can access into the system and get your private key, it's very easy, because you managed to keep the private key not on the hard disk offline anticipate, and often use public networks are vulnerable to hacking, nothing is impossible to hack your wallet very easily for them, so keep cautious in securing all your important files try to save them on offline hard disk.

Many of the past incidents of hacking and fraud turned out to be insider jobs. One example is that of Sheep Marketplace. It later turned out that the owner of that dark market (Tomáš Jiřikovský) was the one who stole coins from the users.

I do not think it is true that bitcoin is immune from hacking and fraud, I believe if there is software that can really shield the bitcoin from hacks then it is good ,but for now we keep an eye for our wallet so that it will be safe, just do not make any false move,

Bitcoin can't be hacked while in the transaction or in a wallet with secured password but I won't say it is against scam because most of the bitcoin scams are happening but it all depends on the person who is scammed we can't blame the bitcoin for scams.Till now bitcoin is the most secured form of currency but its price volatile made it unusable as currency mostly we are using it for money making purpose.

Ok, I hope you understand the difference between Bitcoin <The technology> and Bitcoin wallets <The third party services>. People tend to generalize when they talk about Bitcoin.

Bitcoin <The technology> has never been hacked. The protocol or the software that are running on 1000s of full nodes are pretty secure. It is frequently updates and the source code is validated by proper signatures.

Bitcoin < As the currency, being used in third party software > has been compromised before, but the point of failure was not the currency, but rather the third party software that was used. <Wallet software or exchanges>

So, as you can see, you have to be specific. ^smile^

In terms of technology, bitcoins are encrypted based on blockchain technology and have absolute security. No hacker can crack bitcoin. But there are security holes in the trading houses, and hackers can easily hack into the system, so we must keep the bitcoins in our wallets when we're not trading.

Yeah, it is kind of immune but dont forget that it has been made by people only and it could be hacked if some intelligence come together and tries to identify the missing pieces altogether. Its not really immune as I said but with all the safety features that we have gotten today and if we use them for real then we can actually make it very very secured one. Lets not talk about the anonymity of the same as it is really pseudo anonymous and do not hides itself completely. You can check from where the money is being sent and received and thus if the addresses are receiving bigger amounts then they get the prime targets for the hackers. It could compromise the security of the same.

Even if the technology is immune, the users most certainly aren't. Every human is susceptible to failure and errors and hence they would keep getting scanned every now and then. Not everyone can have the same level of intellect. Bitcoin as a currency cannot be hacked, and it doesn't even make sense hacking Bitcoin. While you can pirate the FIAT money, the same cannot be done with Bitcoin.

That's a really good explanation you good there, just for addition, the blockchain technology which bitcoin currently use is not actually impossible to manipulate but rather really costly and resource wasting.
To modify a block, you need to also modify the whole blockchain because blockchain is basically so many blocks connected and saved to the ledger, and when there's new block, the past block will also be verified, it's like a connected linear line and once you manipulate the data, the line will be cut off, resulting different blockchain system. well that's what I know. CMIIW.

Yes, it is true that bitcoin is immune from hacking and fraud  because it is highly encrypted.

In recent years, blockchain technology has attracted considerable attention. It records cryptographic transactions in a public ledger that is difficult to alter and compromise because of the distributed consensus. As a result, blockchain is believed to resist fraud and hacking.

In every business there are weak loops that hacker and criminal find there way to loot but that dose not mean bitcoin is immune to this same is also applied here.

Bitcoin itself cannot be hacked because it is locked by the blockchain and blockchain has the most secure at this generation but hackings are still  happen but it is on the exchangers not bitcoin only exchangers and people who transactions are p2p.

Your point is irrelevent because nothing in this digital world is safe unless proper security measures are applied to be safe from group of anonymous hackers who are waiting that when you take a wrong move and they have access to your private keys and then all your money is gone.The hacks over exchanges has been increased as reports state that more than $100million have been stolen from exchanges. So btc if safe with you in your wallets unless personal data of investor gets leaked by exchange. So better choose wisely. And you can't stop these hacks but only avoid them.

its really hard to answer this one,because the hacking happens only by chance meaning that most aren't experienced this so minimal answers can be shared,but for my own views i guess your right,the amount is irrecoverable,because anonymity is what may hide the hacker same as the victim

Kindly right on this mate,its the exchanges or the users wallet or storage are hackable not the bitcoin itself,so better not to widen this issue if you arent a victim of this

The stuffs stolen by hackers is always as a result of the carelessness of those holding them. Bitcoin itself is immune from hacking, at least for now, and even when we start having quantum computers, I am sure by then, the protocol would have been rebuilt to become anti-quantum.

Nevertheless, the only way people can get their assets in the hands of the hackers is by getting their wallets vulnerable in which case you either carelessly let them have access to your online wallet login details, or they one way or the other end up having access to your private keys.

I think bitcoin is unhackable today, maybe in future bitcoin can be hacked. it is in my opinion

It should always be immune from hacking because if not Bitcoin could start crashing and everyone would move another crypto. Their targets are mostly  bitcoin exchanges, online casinos and other bitcoin related websites people should stop using these online sites as their main wallet and should learn more about other different bitcoin wallets.

That's not the only way, someone could easily pull an inside job in these exchanges just like what happened with shapeshift

These digital assets once lost is lost forever, because it is developed in such a manner to move in a single direction, which cannot be reversed until the receiver end decide to transact. This is a perfect system, but the same feature has caused users lose a lot of bitcoin. In a recent trade one of the scammer stole my 0.1btc

The good thing however is that as long as we know all the tactics being used by the hackers to get to us, we can always try to stay safe to some very good extent at least.

The main bitcoin itself cannot be hacked, controlled wallets cannot be hacked unless you give out your private keys and except for centralized wallets that you can end up being a victim of phishing attack most especially if you do not have some additional security on, I would say the only way to get to be a victim like you have said is just by being careless.

Actually it was not immune from hacking but people will have a very hard time before they can hack the account or market they are interested to penetrate since the security today is really good and un hackable.

Not everything on internet is hackable. If we talk about bitcoin itself, then it is the securest currency. No one can hack it. Just think, if it was possible, all the bitcoin would have been in the hands of hackers. Blockchain technology is indeed the toughest to break. As it is created by human, it is possible to have some holes but so far none is discovered. The security of exchange can be compromised.

It's not immune to anything since there are so many hacking happens on bitcoins ecosystem and fraud incidents, Remember the old hacks pasted on history but those one are just flavor of history since it can make us learn on how to secure our bitcoins properly. But one thing I am sure if we are so careful and use the correct wallet who have good security then we have less chances to get hack.

Keeping a huge chunk of coin in the exchanges are never recommended. It is indeed the job of the exchanges to offer a better security without sacrificing the anonymity of the user (KYC verification.)

Correct. The securities that cryptocurrencies offer is highly secure in case someone able to control our private keys, the amount that is lost is almost has a zero chance of coming back. Nevertheless, it is our job to educate yourself how to properly secure it, so we can minimize the chance of being hacked.

indeed if bitcoin itself is hard to be hacked, but please be careful usually hacked even our wallet. usually it happens because of our carelessness, which resulted in our funds lost and is unlikely to return

Yes bitcoin itself cant be hacked but bitcoin wallets can possibly be because we stored our funds on it. although hacking can be easily avoided as long as we are verry careful on what we do especially when doing a transactions . phishing attemtps is now verry popular also and it is the same as hacking but in another way. phishers usually spoofed a website or they cloned it from the original ones so that when you paste your important infos such as your private keys , they can then possibly stole it.

Every technology has its vulnerability and that is normal if the team behind the exchanges or any blockchain core has doing nothing to improve the security of its system. That’s why the better the management and cooperation with the team of security experts and programmers the popular the site is. Blockchain itself cannot be hacked,  but companies built around it can.

No one has yet confirm that there is immunity bitcoi  have from hacking and fraud moves, if that is true then it is good ,but I think it was not introduce yet in the forum, if that it is very true , then we believe in it.

While the carelessness can be a great factor when it comes to hacking, at the same time you need to remember that there are many people that lost their coins because they left their money in an exchange, and those that lost money in that way were not really careless they thought that their coins were secure in an exchange, the ones that were careless were the ones that had the responsibility of securing that website.

Yeah, security is absolutely in everyone's hands and as long as you know how to stay secured, you will always be fine. The thing is that hackers cannot actually get hold of our asset unless we give them the access and since we cannot just give them the access freely, they try to deceive people into giving up the full control to their account.

A lot of people have ended up in phishing issues in the past which made their account extremely vulnerable. Some veteran people do suggest to go for separate laptop for only use of handling our bitcoin and altcoin wallets but this may not be possible for all the people due to cost factors but it seems that alone will be a working idea against phishing threats.

The so-called "unfraud" cannot be falsified, which is the characteristic of the decentralization of the block chain.

And putting it on an exchange is like putting money in a bank, and exchanges and Banks are a centralised thing.

Decentralization is the characteristic of bitcoins and the characteristics of the blockchain. Once dug out and held, you are the center of it. You will lose your private key password, and the exchange will be lost.

There are also cases where some programs of hackers and callers exploit bitcoin to accomplish their own bad intentions, which in turn results in disappointment, but these are just numbers. Few numbers have little effect on bitcoin

No it is not. Bitcoin itself is immune but the environment around bitcoin is not immune like exchangers especially people who handle their bitcoins. Bitcoins together with the big lock blockchain is not hackable but the people itself is hackable with the use of hackings like phishing.

I personally believe that no. Almost every month there are some exchange frauds, mining frauds and such. Also nobody is protected from a virus to hack into your wallet and steal your BTC, which happens very often these days. But when it comes to hacking the blockchain itself, seemingly nobody had yet succeeded, and that is the reason why blockchain is still functional.

I believe that there is no one immune from hacking even our bitcoin on our wallet. But we can minimizing that risk by keep our private key safe and use hardwallet. Every online activities is vulnerable and thats why we need always be carefull

There is nothing impossible for hackers, unfortunately. If someone made something, there is always be someone who can break it.

Nope, false bitcoin can be hacked, why? hackers are everywhere my friend, and It can steal tons of amounts of btc, most often these things occur on wallets, hacking can happen through your respective wallets, sadly hackers can break in if they have enough information about you and your wallet. Fraud mostly happens on investments, projecte, and trades, beware and be cautious, this is the web do not expect maximum security on the surface.

Modern hackers are so inventive guys that they can steal your Bitcoins even when you protect your private keys with all the most possible and the best ways.

Obviously and the only way the wallets as well can even be a target is for the owner to end up being careless. At least, the fact that our money is safe as long as we keep it in our wallets, most especially a decentralized one is good enough and most people who are always easily attacked are the ones who either leave the private keys gullible anywhere or probably using an online wallet without some security functions like 2FA turned on. These are the category of people that get scooped off their assets. Basically bitcoin will be secured if we keep our password and following all security measurements. But failing with them, cannot safeguard anyone.

I doubt about it, I think every online transaction can be hacked. but, bitcoin is secure. I dont what happen in the future.

There had been no hack in the blockchain technology, only the crypto exchnages were hacked. You can avoid this by using only reputed exchanges that are more reliable.

As one famous hacker said once, the weakest link in any security system is always people, so if you share your private key with somebody there is possibly a way to hack you xD

Yes, it's true. Bitcoin is being backed by blockchain which isn't hackable. People are getting hacked because of their own mistakes and fault on handling their private keys, passwords and etc,. Exchanges are hackable just like what happened to Mt. Gox, Bitfinex and some major exchanges.

Its not correct to say that bitcoin is hacked in exchanges more times since it is pseudo anonymous.Even hackers hack money from debit cards even though its not anonymous.So,anonymity has nothing to do with more opportunity for hackers.

Why do not have? There are many hacking and bitcoin frauds. Electronic money is a high-tech crime as easy to operate and steal passwords. Or fraudulent in the transaction. Be careful when investing in bitcoin especially when you hold a lot of valuable bitcoin.

I beg to disagree to that, I believe Bitcoin is not immune to hacking and fraud, actually, its value and popularity made it a target of almost all those hackers and fraudster out there. But due to it anonymity and security, it remains safe, but those hackers and fraudsters  targeted exchanges and wallets that is why we got a lot of ways to keep our coins safe from these bad guys. Remember it is our responsibility to ensure the safety and security of our coins, especially because these are all for our family's future.

Is it a joke? People have to keep 100+gb of blockchain on their pc just not to be frauded. But even in this case, if their HDD fails, they lose all the coins)
BTC hacking is impossible to trace so be cautious and dont let your profits wait for hackers on your accounts. Luckily, never lost more than 100$

Hackers are expert in their own fields,they are working good only for bad ways..every one ate vulnerable for being victimized by this kind of people thats why what we need to do is make sure that our crypto are safe and secured..

And fraud maybe your right,cryptonians are immune about this because if youre an active member of this community you will find in every section about this fraud issue

I agree with you that blockchain is difficult or even can not be hacked.
because as long as I join here, I never find blockchain hacked and forged.
I just heard the piercings of BTC wallets and coins ..

Certainly Bitcoin will not be hacked or tampered with, if you know the nature of the technology that made Bitcoin, the Blockchain technology. Others can be hacked off the Bitcoin number found in our electronic wallet, but the nature of the Bitcoin number in our wallet remains unchanged. Bitcoin may transfer the right of use from one person to another, without altering it in value.

there are always fear of hacking

I don't know for sure but I think that wallet with bitcoins can be easily hacked if a person is a great hacker. As for the fraud, there are many fraudsters and scammers today and crypto market isn't an exception

As far as I can tell the Bitcoin network or system cannot be hacked or manipulated because everyone is part of it. Investors should know this so that they are not easily swayed by reports that Bitcoin has been hacked.

Previously, I was skeptical that Bitcoin was not hacked because I had a bit of tech knowledge. I think that everything related to technology can be penetrated, can understand that is also a form of hack. But then, I think I was wrong to learn about Blockchain technology. Basically, blockchain block chain technology is unchangeable data information, meaning you can not unilaterally hack the Bitcoin. Yes, Bitcoin is not hacked.

Unfortunately, bro, here you are absolutely right. Bitcoin and Bitcoin wallets can be hacked. No, it is not easy - I would say, it will be extremely difficult to do, but it is still possible. We have heard about stolen BTC.

in fact there are no major cases of hacking and bitcoin theft. meaning that the wallet technology that stores bitcoins is very safe and immune.

Currently Bitcoin blockchain is immune to hacking ,you are talking here about wallets and exchanges that are hacked before.it is their problem for not securing their server not btc blockchain.thats why people should prefer decentralized exchanges which are fast to do trading and never leave your fund in exchanges or any other wallet other than hardware or client wallet.

Yes we have heard about it, because of people using phishing sites or getting their computer infected etc etc (by their own fault).
Not because anyone managed to beat SHA256 and the btc pow network.

Actually, decentralized exchanges aren't fast at all, which is the main reason the developments in that field progress in a slow manner. In no way right now can it compete with the services offered by centralized crypto exchanges. Another 'negative' aspect is that there is no way to combine fiat to crypto trades in a completely decentralized manner. The fiat aspect will always require permission from the service that's being used.

Regulations forcing exchanges to comply with all laws do however stimulate people to move over to decentralized exchanges, and at some point when the volumes justify actual development (more than is the case right now) in that field, things will definitely change for the better. But then again, not even decentralized exchanges are completely safe from malicious attacks as we have seen in the past. It's meant to provide decentralization, not total protection.

I’m becoming a little bit confused when this question is asked. Normally, when ever I’m asked Bitcoin and fiat (banks) which one is more safe to use in terms of security, I will usually say it is banks, but after reading a post on what one hacker who was arrested by the police in my country said, I’m starting to get confused on which one of them is more safe.

Well, there is always a way you can avoid all these dangers of being a victim of hackers, and that’s by being careful the way you give out information that has to do with yourself. Hackers target you when you give out information about yourself.

I think not because there will always be people that would easily fall for "too good to be true" frauds and you cannot change that unless there is a good education on preventing them or just be moral enough to not scam - there will always be greed for money and they would do anything for it.
I think the blockchain technology and the legit wallets are very safe and stolen or hacked accounts are pretty sure is more on the users' fault.

Bitcoins are not hacked while in the transaction it can be hacked while we keep them in an unsecured wallet but if it is a fiat transaction then it can be hacked while in the transaction too by great hackers.but fraud means if you lay bitcoins to fraud then you will never get back to your bitcoins because all the transactions are irreversible.

I do not think it is true that bitcoin is immune from hackers, I agree that cryptocurrency transactions from wallet to another wallet might be hacked, because hackers are waiting for timing that our wallet be open and expose to hacking activities, and this might gonna  happen.

It is only possible if you let someone know about your private keys or your computer comptomised by the phishing links,when you store and make transactions from an hardware wallet you will be completely safe and it is not that much costly a hardware wallet it is only cost about less than $100.

In shortly speaking bitcoin stability is better than other crypto currency. you know what? Despite of all speculation that bitcoin aledgedly was scam that was many people say and many times that hacker would continuously attack until it will shuting down. Bitcoin is continue their service perfectly. All dominated  things are always on top of the delicate situation because of the people with self interest. That's why you would say bitcoin are prime target of hacker, regarding of unrecoberable fund because of wrong transaction its depend upon the company because before we proceed of some transaction there is a guidlines that must be follow.

bitcoin wallets are immune to hack at any given point in time so we should nt hold the bitcoin in wallets for longer time

Bitcoin network  hacking and Bitcoin hacked from exchanges are two different things. There are many incident that BTC was hacked from exchanges but no any as BTC network was hacked like once verge was hacked.

Bitcoin network is highly transparent and secure only thing one should keep in mind is to store their bitcoins securely in a good hardware or paper wallets and to store the private key secure which can avoid hacking. Some people thing that online exchanges can act as wallets which when stored in the online exchanges the people might loose their bitcoins as the private key is shared in online exchanges so before investing or storing bitcoins in online exchanges store in Trezor wallets or USB wallets which avoids hacking and fraud.

Yes, I can say that Bitcoin is really immune from hacking and fraud more than others. However, I think that it is not 100% safe. You need to be careful, regardless of anything and keep coins in the wallet.

Well, in terms of being immune I don't think so. There has been many news regarding e-wallets and other storage medium that have been subjected to hacking, the latest and most talked about one being that with myetherwallet, which is a popular wallet used by many people. Although most transactions are private and encrypted, there would always be those people who will go to great lengths just to get something, even at the demise of others.

The bitcoin network is very resistant to any type of attack that anyone can think against it, now the problem is that security does not translate to those that hold bitcoin, remember you are your own bank, when you deposit your money in a bank you are relying in their security but when you are holding your bitcoin you are the only security you have and some people do the equivalent of letting their wallet in the floor for anyone to pick it up.

It is not immune from hacking and fraud. We are talking about professional hackers here, who can hack into any device from where they are and most especially when they are certain that they are getting something from their activity. Fraud is also imminent it can happen. All one has to do is to be careful and find out more before making any form of transaction with just anybody on line.

I believe that cryptocurrency is immune in hacking because the code is multi incripted and it was very hard to create a script or a code that will actually solve the algorithms in order to hack a wallet or exchanger.

everything must be done with confidence, because we must know that all without our conviction will not be steady against our stance that we have to live for this.

Maybe yes bitcoin is immune from hacking or fraud but did you think that all of that is because of bitcoin hackers is always want money and I think even there's no bitcoin they can hack any website there to steal the money of others. And even they hack a exchange i think it can't affect the market.

Hackers can't attack blockchain itself because the system is too hard penetrate. Therefore, all the hackers targets the exchange platforms and user accounts on social media. Becausw some person store their keys on the internet which I believe is dangerous. Though hackers can't hack your wallet directly, they can use other methods so beware of these.

Unfortunately, there are many cases that appears now that some people are typically doing hacking and frauding just for the sake of having a lots of coins which is so foolish things to do. Those people never meant how worst they will do to others. Just so hard to think that there are people like that without conscience to do that. However, hacker and frauder is in everywhere without our knowing so the best things that we can do is to be a much smarter and wiser. Be alert in everything surrounding to us and just think very well before we act or do some motion so we can avoid to having connections to those people.

Bitcoin is NOT being hacked. exchanges are being hacked, and that is a very different thing, you are just confusing people in here.
Bitcoins are just like money, and money can be stolen and used for fraud too.

I believe, bitcoin is immune to hackers and fraud, and a hacker cannot possibly turn off all computers connected to other computers which running on bitcoin networks. Actually, that's not immune or unsafe is the exchange system or its human not its bitcoin.

Actually the problems happens from your wallet password etc as the system of it is the same as other accounts of you and when an account from your desktop is hackable then anything can be hacked. You have to make secure your PC from all of the malware and other virus and trojans. If you will get success in securing that then no one will be able to hack your wallets.

All the more bitcoin has been widely know all over the world the more curious and interesting it to all scammer and hacker because they themselves wants the taste of it.. having real money in hand, having many profit without much a fuss that is something for them, they want to experience it too.

I think everything in the cryptoworld can be hacked, I believe there has been an incident in the past where their coins has been hacked and they weren’t able to retrieve it back, now there are still events of hacking every now and then, but the response of the developers of the online wallets or trading sites are just too quick and promt in making their counter measures.

Hacking is an open question, but all sorts of lame phishing strategies would work with cryptos just like with anything else on the Internet.

maybe it's not 100% immune from hacking and fraud because bitcoin is created by human and I think there will be any gap that has a hole to be a hack and it really needs high-skills in programming. maybe it's only a few people that could hacking bitcoin but I don't know about this and I only want to collect more bitcoin.

Generally, everything which is connected with internet, is hard to be immune from hacking. But we have capability of being immune from hacking. You can put your coin in an online an office wallet to keep your coin away from being hack. Online wallet, however, is still stolen easily by hacker because as you know most of hackers is really professional, smart and especially have a high technique to steal a bitcoin wallet if they’ve kept their eyes on. Anyway, everything’s connected through internet brings us a big risk of being hacked, we’d better to be more careful.

I think the possibility to be hacked is there. anyway let alone you save it in online where the internet network could have been hacked by someone. saving money in bitcoin is not 100% safe because the risk like hacking, phising, etc. but you can reduce its risk by storing it properly like in a hardware wallet or adding 2fa security

Yeah I have the same thought that nothing is 100% safe and although bitcoin have a reputation of protecting users from hacking and fraud, risks still exist even with the slightest chance. Therefore, if you don't want your bitcoin to disappear unreasonably, you can store it in a hardware wallet or put it in different places.

yes you are right, bitcoin is currently the target to try to break the bitcoin because bitcoin value is currently very expensive and it is very horrible if bitcoin can be stolen by hackers.

Nope, anything made by man is definitely faulty. One way or another it could be stolen. I mean there are always phishing websites, viruses, and other means to get your data and passcodes. It's all a matter of duping the hackers and following security measure to prevent that. Let's not be those people who thinks thier holdings are safe.

You're defenitely right, we are the ones who are in control with our security so I hope everybody is also aware on how yo avoid fraud and how to determine wether its phishing or not, think before you click as what they say.

Bitcoin is not immune from hacking and fraud because there are still people who will find a way to hack and fraud other people, so not be too much comfortable because they are still many ways to open your accounts. Be alert and be aware in opening websites for you not to experience frauds and hacks.

We all frown at exchangers asking of submission of means of identification for KYC process but this is the only way a hacker can be identify if He or She take the coin to any exchangers that are under going the KYC process.

Hi!

So this is a false point on bitcoin.
Sure of course everything can be crasked. Everything can be copied. Nothing is 100% safe.
But fact is that with current technology, copying btc or cracking btc is...Costly. Extremely costly. In fact impossible with current tech.
The computing power needed to crack one btc adress is soooooooo high that it would be impossible for Google to do it even with all their infrastructure working a whole year.

Furthermore you have to understand that when you "crack" an adress it would be a random one. Including the one without btc that you have in your old wallet xD

Do you even re-read what you post? Probably not.

You point out that it concerns people that hack and fraud other people, so what has this exactly to do with Bitcoin itself? Bitcoin has no control over what a bunch of retards do with their private keys and log-in details from whatever services. If I get hacked, or I lose my private key, it's my fault entirely, and not Bitcoin's fault. If an exchange gets hacked, it's the fault of the exchange in question, and not Bitcoin's fault. Is it that difficult to understand?

Stop blaming Bitcoin for the reckless and incompetent nature of people. Bitcoin is the purest of the purest in every possible way, but unfortunately, people aren't. :-\

It is not immune but we can say that its security is really hard to hack and overcome. Blockchain technology which is where Bitcoin integrated is complicated and requires at least multiple hacks before you can get what you want. Take note that hacking Blockchain technology must be continuous so other hackers use it instead of hacking it.

Maybe Its just your Imagination mate or you're one of those person who criticized bitcoin to make It fall drastically. Just observed and think first mate, If ever that has been real, why there's till many Investors Invest In bitcoin?  It because they understand and believe thus coin that has potential to make a profits rather than several coins.

So far we can say that the whole system of the bitcoins are still cannot be hacked by anybody because if they do then there will be no bitcoins now and that people will definitely gonna be famous today but still even a super computer cannot hacked it by unknown reason so there are a lot of people that is confident in bitcoins because they are pretty much safe than any platforms that are offering the same thing. Look at the value of the bitcoins, they are rising above all

i dont think BTC is immune, every account in the net is vulnerable from hacking... some exchanges deployed best algorithm to reduced the posibility of being hacked.. but still hacking can happen... the only way we could do to avoid hacking is to obey all the advices coming from exchanges. deploying best programs may helps to prevent this to happen.

I guess it was not, sinxe I heard some testimonies that the Bitcoin that they have were suddenly hack by some group of people whom they don't know how, they must be a great hackers and knowledgeable regarding Bitcoins. We cannot expect for this thing to be immune due to the fact that Bitcoin is a very accessible and open forum, less or least requirements for us to enter and be involved here, so I guess it's not.

It is pretty well immune from hacking, but it the case of those who owns or holds it, it is not that secure if they do not really make themselves secure from hacking.

No, I dont believe that bitcoin immune from hacking and fraud.  I think every online transactions is hackable.

As far as i know, there is no case that there is a hacking that totally succeed against bitcoin. The hacks that i just read are hackings against the exchange and wallet that support bitcoin but directly to bitcoin? There is no case. So i think that bitcoin is a really safe cryptocurrency and it is not that easy to be hacked unless you use a quantum computer.

after techonolgy about hacking developt, many various technique and ways to hack all security system.included bitcoin wallet and other crypto wallet, there is still a bug that can still be penetrated by hackers

Right.For nine years of existence,not even a single man had succeeded to hack bitcoin directly.I believe a lot of people around are fond of hacking but when it comes to bitcoin,it could be very impossible.Though we heard lot of issues against bitcoin particularly on scamming,we all know the fact that bitcoin is just being used indirectly.

Immune to hacking? no not at all it is not totally immune client sided, exchange, online wallet services, and individual holders can be hacked that would always depend on how they are going to secure their private keys and their online exchanges, compromised wallets and exchanges when the culprits made to move the funds then it is irrevocable but it is traceable.

In the past it doesn't have the resistance to withstand hacking to large extent, and by those day the users were low in number. Now as the growth is attained, the immunity to stand overcoming hacks were developed in a better way. Example for the same is the decreased number of hacking related news these days. When it comes to fraud, most of the time we're responsible for it.

I think bitcoin can still be hacked. But if we keep our accounts secure and do not tell anyone the information or the security code they exchange, I guess nobody will be able to steal your bitcoin.

Cryptocurrency is not immune from hackers but the fact that most of the markets today and wallets today are safe enough to place your coins because of the multi encrypted private keys that no one can easily get that, so we can still rely on exchangers or wallets for our coins to be safe.

Bitcoin is not immune from hacking nor fraud. There are a lot of smart hackers that will find way to hack, the reason there is no such thing as a impregnable security on the internet. In terms of fraud, even if you have a high security application, but if you don't have enough knowledge how people can fraud or fool you, it will still not be safe.

Maybe several people think the bitcoin immune from hacking and fraud. But I think Bitcoin is hackable. Every transaction is not safe. Hacker can learn it.

Bitcoin are also works with in the internet soul hackers can be possible to hack Bitcoin. Hacking is not an easy thing for bitcoin if your wallet outside will it be hot today it is some major mistake happen again that sites so be alert be safe with your wallet or something like that everything will be happening in this today's world

hacker has several methode and technique to attack our wallet.if we careless about our wallet security by opening unknown source email or link , they can attack us from this.

Experts have established that bitcoin-wallet can be hacked through vulnerabilities, which are currently available in cellular networks. This is a vulnerability in the networks SS7.When hacking the system, specialists need the name, phone number, some other information.

Bitcoin wallets are becoming stronger and immune to hack day by day. I once read a news last year about Coinbase paying hackers around the world to hack their platform and point out every vulnerability in it. Through this way, they were able to detect the vulnerable sides of their platform’s security and improved most of it. So I believe that Coinbase is one of the safest wallets to be used. I also use other wallets, but still everything depends on you and how careful you are.

No doubt all the crypto currencies can be hacked because these are digital things and we don’t have a physical grip on them. However, the person knowing coding can easily hack our coins and we can’t do anything to stop him but it is not as easy as it seems to be to hack crypto currencies as the companies have this thing in account and are working on it all those years.

In digital world, our account can be hacked and stolen. The safest way we can do is we keep our bitcoin or altcoin in hard wallet. If we dont have hard wallet and using web wallet, better always keep private key and not share it to anyone

There had been no hacking in the blockchain technology so far. Only some exchanges were hacked but if you see recent news even that has not happened recently.

Nothing is completely protected. If professional hackers want to crack a bitcoin wallet, nothing will stop them. A lot of scammers are ready for anything to pinch more coins from bitcoin pie. But bitcoin strive to make this task more difficult for them. However, for those who work with crypto-currencies, it is always necessary to monitor information about fraudulent exposures and to treat private information with responsibility.

It is too difficult to hack an established and encrypted bitcoin wallet, it is much easier to phish for information and then use that to gain access to it. Operating Systems and browsers have more vulnerabilities so those are most likely to give away your passwords

Bitcoin can be hacked. It can be due to your carelessness or the hacker’s cleverness. If you are managing your wallet on your own, someone else might obtain your private key by getting into your email (if that’s where you keep it) or even seeing the private key in the physical world. Some of the more notorious Bitcoin-related hacking stories this year occurred when companies held so-called “initial coin offerings” (a form of fundraising) and asked investors to send them Bitcoins. In certain cases, clever hackers impersonated the companies with a fake website and persuaded the investors to send millions of dollars worth of funds to a different Bitcoin wallet. Once the Bitcoin was sent, there was no recovering it, and both the companies and investors lost their Bitcoin.

I agree with that fact that no one is safe from hacking or compromising the system, but it can be avoided by doing some precautionary measures.

Holders should hold Bitcoin tightly. You need to know what's been happening in the world of Internet, at least you always should use the strength password and also 2FA. Hacking is still possible, but with this you can add a little protection. If you want to get full protection, you can use a very strong wallet like flash card for this.

No Bitcoin is not Completely immune its just can't be hacked or fraud directly. But it is possible to hack the exchange or scam the users who has bitcoin is their possession.There is always some ways to hack anything about every Hacker is a part programmer and every Programmer knows how to find solutions in a creative way.

It's pointless to talk about exchanges getting hacked or people getting scammed since it has nothing to do with Bitcoin at all. Exchange hacks are caused by human incompetence, and scams more often than not as well. Almost every crypto currency has proven to not be immune to any sort of blockchain rollback or 51% attack (not even Ethereum), and thus far only Bitcoin managed to remain clean. The only attack (as far as you can call it an attack) on Bitcoin that has been successfully carried out was that miners managed to spam mempools to the point where fees reached a high of +$50 last year. I'm glad that this will be dealt with once LN turns in full working state.

the hack of mt gox have shown that the stolen coins are irreversible and lost forever, but the immunity from hacikng and fraud still exist as the wallets stolen are from exchanges and their lack of security.

Fraud is something outside of Bitcoin, so you can't blame Bitcoin for others tricking and defrauding others.

Hacking is applicable to all agencies no selection for doing this as well as the thing that really big help to them specially in exchanges even in some government site was hacked by the hacker, so we have to prepare on this because hacker can attact anytime. If ever they hacked the exchanges make sure you don't accept immediately the anonymous person who would be able to convince you in any kind of attractive they offer to you.

Bitcoin cannot be hacked, if it was then bitcoin would have been hacked a long time ago, the ones that are hacked are the users or exchanges and most of the time this happens because people are not as careful as they should be and this is why people keep losing their coins, it is a shame because I would have thought that the people using cryptocurrencies were more sophisticated and knew how to secure their coins.

so now many projects offer security for wallet, thus giving immunity from hackers. it is very useful for large corporations that store many cryptocurrency assets, because once lost, it means lost all its assets

Yeah because of it makes all the things that are in online investment will always have risks. moreover we do not know with whom we work together  right ? because everything is anonymous. so you have to be careful with scams and fraud. to save money in bitcoin if you're careful. everything will stay safe

A lot of high secured exchanges are now everywhere on the internet since the biggest hack of exchange at MtGox at the past. There are still some exhanges that is vulnerable to hacks and that is a proof that there are no sites that is immune to hackers. All sites or even exchanges are vulnerable to hackers, it is just that there are some are hard to be hacked.

There is no safe site in the internet all of the websites are still vulnerable to get hacked by the professional hackers and that is the reason why it is not safe to keep our bitcoins or even the cryptocurrencies to the different exchange for a long time because it is not worth it and it is best to invest to the hardware wallet to increase the security level.

Of course not.bitcoin is prone in hacking cause if you are a hacker you will hack something that you need.and you need money for everyday  that is so important that you arrange your account so they didnt have by any hackers nowadays are the best cryptocurrency and it you will do.

A good explanation for many beginners. They simply want to make money quickly without doing anything. Not everyone knows the details of the exchange or bidding associated with crypto.

You can hack everything, but there are very few ways to do this. If you drop the option, when you steal a unique key, by penetrating your computer - then there is only the option with the selection of this key.

Actually Bitcoin can not be hacked or cheated if you do not create a loopholes for the hacker to do so. Accessing the unknown site as well as providing information related to your wallet will help hackers hack your wallet easily.

I dont think so, Cause bitcoin has a hidden transaction.Scammer,Yes this is immune of that but hacker ? I dont think so , i dod'nt read already news about hacker in bitcoin.

Hardware wallets are expensive but it offers the best security and privacy that your wallet can have so those who really have high number of assets see to it that they buy hardware wallet. I totally agree that there is no website that is safe from hacking and since bitcoin and all other cryptos uses internet in transactions, there is a chance/possibility that wallets can be acquired and accessed by hackers. I don't know about MEW because I noticed that many of their wallet users are being hacked which includes my brother.

I used to think that as long as I am the only one who knows the private key, my wallet will be safe. But I guess that this is not true because hackers are hackers who will find any means to get wallets who have valuable coins.

Bitcoin's technology - protocol and cryptography - has a proven, high level of security, and Bitcoin's network is probably the world's largest distributed computing project. The biggest vulnerability in Bitcoin is the mistakes of the users themselves

There had been no hack in block chain technology so far. Some exchanges were hacked but it is the fault of those exchanges.

Unfortunately, this is not true, we already know a lot of cases with breaking of wallets ... Be careful when using your wallet, there is a threat at every step ...

As for me, i believe in Bitcoin and its security. It is created long time ago and working till now, and not hacked yet. If to look for personal wallets it don't concern to Bitcoin, it is yuor own thing. Only can be the reason that hackers can hack you. Simple way.

I think Bitcoin has never been hacked. but It was the negligence of its users. Their wallets had been hacked. talking about fraud, Bitcoin is definitely not a fraud. There are just people who use the name of Bitcoin to scam others. so be careful to whom you're making deal with.

but several times ago we heard about wallet hacking, even myetherwallet injected by hacker.and much balance lost.no one can guarantee about wallet security after hacker have various technique.

Well, I don't know when but quantum calculators will be able to hack blockchain if it won't upgrade.
Probably it will require 20 more years, but they are coming! https://en.wikipedia.org/wiki/Quantum_computing

When everything turn into digital, it can be hack so although the transaction mobility is high , the greater risk also upon it.
So make sure that you've learn very carefully how to keep it safe all the time, always update the security to prevent from hacking attempt.
It's for your own good !

I wouldn't say immune. Although one might say that it is secure and private at best. I wouldn't say that it's secure because there are other means that could threaten the safety of one's coins or holdings. One of the usually exploited means is with the storage system or e-wallets, which are commonly subject to either hacking or bogus schemes like fake airdrops that only aim to get one's e-wallet password, which have already victimized many people in this market.

Anyhow, Bitcoin and the other altcoins still remain the safest currency. It cannot be compared with fiat. Traditional money that is stored in the banks can be hacked easily. We hear this hacking stories often.

Everything can be attacked not only by electronic money but by cash. Since I think there are people out there, it will definitely have people breaking them. That is the natural law in society. They can all be bad actions and beautiful expressions in all aspects. And every investor's job is to know how to protect their assets and invest wisely.

You need to protect your email account using two-factor authentication to prevent attacks. Do the same with your bitcoin storage service. Coinbase already requires a two-factor logon to the system: it consists of a password and text received via SMS. SMS can be intercepted, you must use the option of scanning based on an application, such as Google Authenticator

I think the exchange will still have a record of the number of coins owned by investors, unless they also want to be cheated because in the true sense, it is stolen money and not records.
Hacking an exchange account will not affect the investor's personal account with an exchange.

of course it is. If you give someone your private key then it's your problem. Luggage pads in such a way that the password to pick up to them is unrealistic. The rest of this is already you need to be careful that someone does not upload your data for hacking

So long as humans created, maintained and is using something, it will be subject to hacking and fraud. I mean no human made object or system is ever perfect so it would always be vulnerable. Same can be said to crypto currency. No matter how many bits of security you use, if the person is careless with their transactions then it will be for naught.

The best thing is the algorithm of bitcoin system, it is anonymous. Where will they find from millions of wallets are to be hacked and whom account has millions worth of money. scratch your head and give up.

Cryptocurrencies are prone to hacking, and also it can be wiped by computer crashing and other unexpected events. But its difficult to hackers to know if their victim has millions in their wallet. Regular changing of password and avoid giving of your password to anyone expect to your wife ! it will be a war LOL!

Well, for me, as long as we have a money that works around the internet, it is vulnerable to hackers. because internet is the most dangerous place to put all of your money. so still, it is vulnerable.

No i believe bitcoin is not immune in hacking and fraud because there are a lot of hackers and would like to trick people today. This also the reason why the governments of a country don't like cryptocurrency because they think it is just a scam to steal all of your money.

I think that depends on how to secure the site to prevent attackers and how well the support system and IT team will protect their site from hackers. I think that every exchange will secure their site so that their members can trade in security.
I'm not sure about this because bitcoin is hard to hack but if someone has high skills in programming he might crack his account but of course, he needs to break the private key.

The blockchain itself is totally secure but it is still up to the user how they manage their personal keys/ crypto corporations

There is nothing safe in the internet world, everything can be hacked because all sophisticated systems still have weaknesses. Weakness is used by bad people to damage or steal. Bitcoin can also be hacked, for example in Coincheck, the exchange of virtual Bitcoin currencies in Japan, losing 523 million NEM coins (Japanese cryptocurrency) worth 58 billion yen. Youbit from South Korea lost 17% of its digital assets. Gox, based in Tokyo, Japan lost 750 thousand Bitcoin coins

I agree that trading platforms are the target of hackers, but because of its anonymity, people can easily send illegal coins.

we often see in market much exchanger or wallet hacked and millions dollar stolen.no one safe in any place in this world.people become smarter since technology developtment growth massively.

Hackers can only steal your information, and you can't steal your block directly. Do you know the famous blackmail event? It makes Bitcoin's reputation louder. I think you should go to learn the blackmail incident.

Bitcoin is secure and it is good because it can not be hacked easily while the fraud chances are very less and in fiat money there are high chances of theft while your wallet can be stolen any time but in crypto your money is highly secure and every where you can go freely and from there you can pay amounts online from your online wallet so it is a great achievement of blockchain technology that now we are getting the benefits from it.

Exchanges are lot vulnerable to hacks due to the fact that there are many unpatched security flaws of which the hackers take advantage of and gain lots of money. But your second statement is absolutely right and we can never recover the bitcoins from a lost wallet if you aren't having any backup of it also the bitcoin wallet can never be accessed without a password if it is password protected and the security is also pretty tough and will take many centuries to be bruteforced.

My opinion is different because bitcoin can be hacked and fraudulent. Indeed, most hacking because of our own carelessness can be the entrance to hackers in stealing bitcoins in our e-wallet. An example is the incoming email that guides us to tell the private key that is unwittingly the hacker's actions.

Bitcoin itself in my opinion is hard to hack, because it has to break many blocks, and what is usually hacked is a wallet that contains bitcoin. they take all our assets and disappear without getting rewarded. indeed it mostly happens because of our own carelessness, so keep concentrating while accessing our wallet

Bitcoin is reliable. In future, there could be something which comes with changes on blockchain, but I think that banks are gonna suffer more than blockchain technology. Banks will have to move their jobs to blockchain in future.

That's wishful thinking. It's as if you're saying that banks aren't adapting. Banks evolve along with time and possibly at par with crypto in the future. Who knows. But technology advancement also is accessible to hackers so i really don't think any of these is a hundred percent safe.

I think Bitcoin is quite difficult to hack, it is easier to hack an exchange than Btc

for personal wallets, I think it's safe from hackers. transactions carried out are also safe from theft. so far the one who is still vulnerable is the exchanger that hackers can still break.

Yeah there are so many wallets which can be use to prevent lose and hacking, there are so many wallets that are unbreakable and unhackable because it has private key until you share your private with anyone, no one can hack your wallet, blockchain is the best wallet in this regard, to avoid fraud try to increase your knowledge and information.

as long as we are wise in using it I think it will be safe, unless we are reckless, allowing hackers to enter your wallet. many ways they do to trap us, so be careful using your internet channel

I do not believe that bitcoin is immune to hack .
Again,once one losses funds to hackers , the wallet address where the funds was transferred can be tracked but the funds cannot be recovered because there's no way of tracking the hacker.

In the world of computers, nothing is always safe. Hackers may find their way into the system as they become more knowleadgeable about it. But don't worry, currently I haven't heard that much about hacking bitcoin exchanges. If there is any attempt, I am certain that all eyes are watchful. Anybody doing it can be caught red-handed easily. Fraud on the other hand is always happening anywhere and it is common on the internet. One time I almost believe that a certain page I came upon to visit, was offering a free cracking of bitcoin address where you can get atleast one or two bitcoin. It said it was free to try but later I learned that it was just another trick to make you pay an amount that will go to their account. An online chat is available where people would be seen saying thanks, thank you... etc as proof of its authenticity. Don't be carried away. Beware!

 

As long you do own such private key of such wallet then its really not easy to be hacked as long those keys are still safe and kept from others awareness.
Risk of losing still exist though but chances will vary on how a certain user is sensible to keep those important informations.

If it was hacked by someone very clever then we can do nothing about that but how about we are being tricked? What I mean is that it is not that far when we are going to tackle something like an inside job but who knows? These are just guesses but this could also be possible am I right? As long as poeple are careful about their funds and keep important information like private keys away from prying eyes I think everything will be fine.

Bitcoin itself cannot be hacked and believe me hackers have tried everything that they could throw at it and they have failed, but they are really smart and they have found out that is way easier to hack the computer in which the bitcoins are stored than to try to hack bitcoin directly, this is a huge problem because as we know once you send your bitcoin out of your wallet there is no way to get them back so if hackers get access to your computer even for five minutes they will steal everything that you have.

Bitcoin is the most safe and secured investment in all the time so if anyone trying to fraud you it will not easier to get your Bitcoin out from your wallet is not a simple thing so I think the power of production is more higher in Bitcoin more than anything you will definitely trust this.

I think you only see from one side, because anything in the online field must have the risk of hacking and fraud. It all depends on how we maintain our investment and how strong the security that we use to make it untouchable by hackers. Not everyone has the same skills, investments wherever there is nothing safe when they do not have skills about this. Even if you know, there is a lot of news if the exchange has been hacked etc., do you not realize how strong their security is. Those who have strong security can still be touched by hackers, so all have different risks and will not be completely safe.

Everything is possible in the online world. But we should accept that btc is more secure than the current valuable paper. Yes, btc can also be hacked, but for now it is a safer choice.

as long as we don't do things that can threaten the wallet, I think it will remain safe. a lot of their ways to grab the contents of the wallet. complacent is one of the most factors that can eliminate our assets

There is no such thing as safe or secure when it comes to invest thing because every investment that has money involved is said to have a risk . infact the risks in bitcoin and in crypto are more larger than compare to other invetments out there because bitcoin are verry volatile or unstable  . however more risk is equals to more reward ( as the popular saying said  )

Bitcoin itself is not hackable so yeah its immune but right after we buy and put the coin on a bitcoin wallet or to an exchange , that was the time that we are expose to cyber attacks  .

Hacks can happen, but there is no hacker who can break the bitcoin code and get any bitcoin address private key, but hack and fraud can happen on anything if people download any software they see and not check before.

I do not agree that bitcoin is immuned from hacking.
The security risk associated with the transaction history on the blockchain is becoming a leeway through which hackers get information on the amount that is contained in a wallet and then strike by hacking the wallet.

And yes , once funds is lost in the blockchain , there's no way of recovering it.
