Bitcoin Forum

When most people first hear about Bitcoin, they usually think there is some way in which the peer-to-peer digital cash system could be hacked. This is nothing new in some ways, as many internet users have seen their Facebook, Twitter, or other social media accounts come under the control of a nefarious actor over the years.
Having said that, Bitcoin is built for security. Due to the large amount of monetary value that relies on the world’s most popular cryptocurrency, the developers who maintain the de facto reference client for the Bitcoin protocol are careful about any new changes that may be made.
I think Bitcoin depends On Open source.
The Power of Open Source
One of the main reasons Bitcoin is viewed as secure is due to the fact that the codebase behind the network is completely open source. Anyone who wants to join the Bitcoin network is able to do so in a completely open and incorruptible manner. New users are able to confirm, if they wish to do so, that the financial network works in the manner intended because they are able to verify the source code that they’re running on their home computers.

Of course, many users don’t actually verify the code related to their interactions on the Bitcoin blockchain. Most users simply purchase some bitcoin on an exchange like Coinbase rather than worry about operating their own full node.
But the point is that the option to run a full node to control one’s own digital financial sovereignty is always there through the use of open source software

Technology  has very vast field nowadays. l worries ,when heard some bad news of hacking about money from media.they have applied the different types method of  hacking.what will be happened if hackers attack on bitcoin.

Bitcoin is known for its security because its code based and its transactions is peer to peer and encrypted its really difficult to hack bitcoin but hackers attacks on exchanges and other wallets and they steal bitcoin from that platforms but sometimes we hear about hack the bitcoins from that exchange then this is the definitely scare us because its a technology and it can be Breakable.

It is impossible because Bitcoin is really famous for its safety

The only way to hack the blockchain will be a huge neural network with AI. Actually it is over possibility of technology, but as we know, for every law will be ever a breakthrough.
Anyway BTC and blockchain still are the most secure system to transfer values.

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.

I read that Bitcoin can not be hacked with the current technology, but I did not investigate the source and accuracy.

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.

The cost of hacking into the blockchain is up to $ 50000 and the success rate is 0.01%. It is almost impossible to hack the Bitcoin system

Very possible can bitcoin hacking because of technology now very updated in a latest version and some of the peoples will used there capability to hack bitcoin because of there brilliant talent.In this casea just need to protect as early as possible can hackers cannot enter.

so much possible for bitcoin to get hacking, as they are with anonymous system so no one knows when is the bad things will happenning. The only way you can avoid your assets is just be inteligent in every single things you will do, if you wanna go to the exchange look at the link of those site clearly and make it true. So goodluck out there.

"Hacking Bitcoin" is a wrong term caused by the media as it is short news to look attractive, for example, "Bitcoin hacking: more than 1 Billion dollars lost" Although the correct news is "Bitcoin exchange platform hacking: more than 1 Billion dollars lost."

Bitcoin cannot be hacked because it is a peer to peer, but it is possible to hack trading platforms because it is like banks "third-party" that does this process. If hackers have access to the administrator's account, they will be able to send Bitcoin into them addresses.

There is no relation to the open source [ remember -----> Confido ICO 'exit scam': Founders disappear with $375,000  (https://www.cnbc.com/2017/11/21/confido-ico-exit-scam-founders-run-away-with-375k.html)]

Yes Bitcoin is now hacking. There is a lot of advances in the world of technology. Hacker hacke  Bitcoin. Stealing from Bitcoin. Hacker are very strong. However, if we are aware then solutions can be found from this problem.

Everything is possible on earth.. Bitcoin can be hacked when ever.Change is constant.one can never tell it all'Thats my own believe.

Depends how you define it, but someone could find weaknesses in one or more of the crypto algorithms that are used in Bitcoin. There's also been exploits before, like the xxx billion BTC block back in 2010. You could call that a hack perhaps.

I do not know, but I thought that there were no cheats for bitcoin, but with our technology, every day that could be released was impossible, so maybe there are hacking for Bitcoin

don't confuse a bug which was caught immediately and invalidated right away with an exploit or a hack. they are two very different things. a "hack" of the bitcoin protocol is impossible and has never happened, not even a close thing. a "hack" of wallets of users has happened a lot though. and it is always due to lack of security on the user's end but sometimes because of the wallet provider's mistakes. like the issue with blockchain.info random generator on their mobile wallets which led to some fund losses.

Hacking bitcoin is impossible if any country wants to fail bitcoin currency it should have to hack every one wallets.

Bitcoin hacking is not possible without wallet key, password but if hacker to get your wallet information then hack is possible.so we also need hide our wallet information and don't click anyone false mail,Link etc.

But it isn't that we never fall into that situation. I think the problem is when someone gets our wallet key, how can we protect our wallet? Once we lost wallet key, it is difficult to verify, who is own this wallet, who is not.

What you say is true. To hack bitcoin is a very impossible thing for people to do. Because some technologies like OPEN SOURCE are very helpful in maintaining the integrity of bitcoin. Plus bitcoin is very centralized with BLOCKCHAIN technology. That is a very impossible thing even beyond the reason of the human mind to be able to hack bitcoin.

Nothing can penetrate the technology that is blockchain even the government and banks acknowledge that fact, But the right thing to say here is the exchange or wallets that are online is the one that are attacked by hackers to get their stored bitcoin and not the system at all, But this can also be prevented if they only used offline wallets or cold storage wallets to store their bitcoin is a great move to o unless you can afford in getting one.

It's impossible.blockchain technology is very safe.If you want to hack you wanna hack so many computers.

Bitcoin is very hard to hack because it depends on the system it is built on which is the blockchain. The blockchain is built to be secure because every block depends on the hash of the previous blocks. Even hackers with the best skill cannot hack the hash keys because it takes lots of time and energy to acquire it.

Until now no one has been able to hack bitcoin. Both from personal and community. With Blockchain technology hackers are required to hack millions of servers simultaneously to break into the defense system of Bitcoin. And as we know it is not easy.

For the people who says it is impossible to hack, I am disagree with your opinion. Because you know guys I've read here in this forum that one man who actually lost his bitcoin because of bullshit hackers, I am so sad when I heard his story because it's hard to earn money but there are some people who do evil doing such as hacking an account. I suggest to professional that we need some alternative in order to prevent that hackers.

until now hackers have not succeeded in penetrating the security system of bitcoin wallets and that is not possible, this system has been clad in meetings of various owner's secret codes, bitcoin theft only occurs if someone has been trapped and provided a private key to hackers

It may be impossible just for now and I think this is not a problem, when technology will be able to hack bitcoin, bitcoin will take advantage of that technology as well.

Hacking won't be possible because of the way Bitcoin is built in the blockchain. Miners would be able to spot on fakes transactions no matter how hard they try. This is why I love the blockchain, no one will be able to control it no matter what they do.

I don't think bitcoin itself cab be hacked.
But even though if it's gonna be hacked, then it has to be with the latest Technology maybe such as the AI or maybe the Quantum Technology that was just test-run in China a couple of weeks ago. I think bitcoin is been coded on a sort of code that can withstand any sort of hacking. Hacking bitcoin, I think it's going to affect the whole of blockchain.

I see the loss of bitcoins due to hacking only in such cases

• Your exchange platform was hacked
• You gave access to your wallet to someone (social engineering, or stupidity)

In the entire history of Bitcoin's existence, there has not been a single serious security and burglary incident that has led to fatal consequences.

Less possible options to lose your Bitcoins

• An error in the system code that leads to vulnerability.
• Hacking of private keys.
• Capture control of the blockchain ("51% attack").

Sad to say but if can't deny the fact that bitcoin is indeed hackable. Well it's possible because it's in digital form and we all know how hackers can do their job in the internet field. Good thing is we still have a chance against them if we're just gonna take care of our bitcoin properly. Its safety depends upon us so we need to act wisely every single moment.

No matter how perfect was not the security system in any case, there is always a loophole to the next transaction did not come to the address where it should have been. Technology is running ahead and hacking is no exception. He is the engine of progress.

Nowadays scammers and hackers are everywhere so we must be take carefully to our coins. It is very possible to hack our account.

Hacking Bitcoin wallets may actually be a tall order for anyone who embarks on such frivolous activities. However, I do not think this is not impossible as there could be programs written by some genius........

Hacking bitcoin for me me is not possible , because it uses blockchain technology so that all datas are stored on different units. so that hackers cannot easily penetrate , he must hack all units before he can hack btc. It is a very secured system.

i dont think hacking Bitcoin will be possible,,because Bitcoin isone of the famous coin that any body can have acess to

bitcoin uses blockchain technology, where each chain is connected and never interrupted
if there is a new bitcoin, I think the chain used will not match
so, it will be very unlikely, BTC will be manipulated

By 'Hacking Bitcoin' I'm assuming you mean either:

A: The possibility of a hacker being able to access your funds that are in cold storage, or..

B: A 51% attack on the blockchain due to a majority of malicious nodes.


As for A, in order to crack a bitcoin private key it would require an extreme amount of computing power that we currently don't have access to today. In the future however, even 10 or 15 years away, we might have something capable. This is why many other projects in this space tout their 'quantum-proof' solutions, to avoid the possibility of quantum computer hacking. However, even if quantum computers were widely used, the Bitcoin blockchain could simply fork and add in their own quantum-proof solution. So it's extremely unlikely that it is hackable in this area.

As for B, "The majority decision is represented by the longest chain [in the blockchain]. If a majority of CPU power is controlled by honest nodes, the honest chain will grow and outpace all of the other competing chains. [To commit a 51% attack], an attacker would have to redo the proof-of-work of the block and all blocks after it and then catch up with and surpass the work of the honest nodes" (BTC Whitepaper). As the difficulty of mining blocks is determined by a moving average, it makes it almost statistically impossible for a 51% attack to occur. Like winning the lottery two times in a row level probability.

As for 'hacking' into your funds on an exchange or some other public place, pretty damn likely, but those cases are definitely not bitcoin's fault.

I don't think that anyone can hack Bitcoin and the most stories I heard are not hackers or criminals hacking but hacking exchanges and other sort of systems to get Bitcoin and in most scenarios individuals lost huge amount of money instantly and also some hackers target Bitcoin or other currency holders specifically in many ways so it is our responsibility to take precautions in any situation

I think hacking is the hackers job for which they are using the latest technology through which they can easily hack near area wallets and they can hack your wallets once you log in they have capture your IP and then they trace your log in and passwords so they use this way to hack you bitcoin and finally they steal it with out any problem.

Unless you get a quantum computer, blockchain and Crypto is not hackable.

In theory, we can hack Bitcoin and altcoin by some methods such as:
  + Attack 51% of the network
  + Use try search method of address for private key already contains large amounts Coin!
  + Use Wallet app errors and bug!
But with the current technology and computing power, it's still very hard to do!

I agree. We can't protect bitcoin as a whole, but we can take personal precautions like you mentioned, and those go a long way.

Of course, Hacking is possible in Bitcoin. There are no possible in an Internet. Since, the Internet become popular the hacker is also active. And many people are confuse what internet can do so they are exploring. But as time goes by they used bitcoin to their own purposed. Its Hard to believe in many malicious sites today because it can hacked your personal things in your phone, laptop or personal computer.

In fact, check the source code of bitcoin and monitor its updates - several hundred or maybe thousands of people in the world. These are specialists or those who are associated with the development team of the bitcoin core. The rest of the people and the more ordinary people - never even thought about what to check or look at. They do not understand anything about this. This means that if once something happens with the bitcoin code irreparable - the world does not immediately know about it. I'm saying all this to make it more clear that the bitcoine ecosystem is built only on trust.

This news sometime has two meanings if we dont really investigate but in my opinion that bitcoin is very complex system in blockchain and it can not be hacked. The news recently about hacking is about thr wallet. If we dont be careful to save our detail for wallet then might be hacker can be hacking our wallet easily. Not bitcoin which can be hacked but wallet of bitcoin.

as far as I know bitcoin is hacked and impossible to do

Though i don't know much about bitcoin but I at least know that all the bitcoin are kept in a secured wallets and it is impossible to hack those wallets.

so far it is very rare that bitcoin events occur, if what you mean stealing in each bitcoin holder's wallet is impossible.
highly encrypted security, except for theft in the trading market.

Bitcoin is based on Internet or we run it through Internet and those thing that run on Internet is very much possible to hack and it is our duty to protect our things.

Hacking bitcoin is possible, in fact the hacker still do it every day. If one day the protection wall is not firm enough then the world will get in trouble

Specialists whom I trust claim that this is practically not possible. Program financial resources together with huge technical capacities can not recoup the effectiveness of hacking.

The first time I heard about this, it was not fair to the real investors, because bitcoin could be a left hand job for many people outside the main job so let's create a public market in truth

Yes, the Bitcoin software is basically Open Source, but the problem is most people are not using the Open Source software to

access their coins. They use proprietary software with third party service providers, like Exchanges & Wallet providers and the

hackers knows this, so they target the weak links in the chain, namely the software that are most commonly used via these

third party service providers.  >:(  {We saw this with MtGox and some of the lesser known Wallet providers}  ::)

Bitcoin uses blockchain technology and it is very secure and safe also those are some Bitcoins build purposes and qualities to become a global currency. To achieve such a target it should posses advanced options that other fiat currencies do not posses so it is fail safe by design hi according to my understanding hacking Bitcoin is impossible at the moment   

agree that it is not easy to hack bitcoin because it has been made in such a way that its security and everything is usually a mistake of ourselves to how to look after it

Bitcoin and altcoin can be hacked theoretically, but practically impossible. Some of the possible methods are:
Attacks 51% of the network
Bug of Wallet software
The Private key of the address available (containing a bitcoin or altcoin attraction)

We all know that bitcoin has millions of investors around the world and there are millions of people who find bitcoin so trustworthy and no only people there are many countries like South Korea 🇰🇷, Japan 🇯🇵 and few more that has legalised bitcoin and then big companies like BMW has also started accepting bitcoin and this is all possible because of the most safest and the confidential transactions of bitcoin as its transactions does not involve any third party seizure and it also provides user anonymity.

seeing many social media networks being hacked doesn't mean that bitcoin can be hacked, the manager of the most popular coin of the world which is bitcoin has been working day in day out to ensure that the large amount of money committed to this project does not go down the drain. so i believe bitcoin is secured even though i cant categorically say that it cant be hacked but i believe with the security measures that has been put in place, bitcoin is secure to an extent.

At the current moment, hacking the blockchain technology itself it's impossible BUT does not rule out the fact that it can't be done in the nearest future.

The security offered by the blockchain technology is second to none and I hope more advancement and improvement in the technology to give it a good edge to witstand whatever challenges (as per hacking) that may want to surface in the nearest future.

We are in modern generation with modern and high technology plus the knowledge of the people that's why hacking bitcoin is not possible. But you can make your bitcoin secured just keep your password and private key safe that nobody knows but only you,don't share it to others. Then don't put all your bitcoins in just one wallet.

There are some many hackers now we need to double secure our wallet,those  hackers do anything to hack your wallet and get your bitcoin.

I think hacking wallet system is common to centralized exchanges since it is always an online platform, so hackers use this to their advantage. Decentralized exchange or cold wallet is not easy to hack except there is a lead to the wallet information.

Of course, bitcoin is cryptocurrency, it is the encrypted currency. Encryption is one of security system. So, basically there is no one can hack bitcoin.
The most hacking cases occurred are because of human error itself. Because of that, when peoples want to enter cryptocurrency,
they should study about how to protect their wallet at least not to getting phished by others.

The manager of the most popular coin of the world which is bitcoin has been working day in day out to ensure that the large amount of money committed to this project does not go down the drain. It is always an online platform, so hackers use this to their advantage.

Why it is not possible, hackers are also upgrading themselves with the up gradation of every system and  every system that runs through Internet can be hacked.

What do you actually mean by this? A full node can control the sovereignity of all? I think you need to rephrase this, don't you think?

Hmm it is hard to say. I think that hackers will attack on the network and make 'double spend', but in fact, they prefer hacking your wallet or exchanger.

Bitcoin identity can be stolen in any way. I found myself authentic with my identity, stole my ether and facebook, and because of this my identity has become very worthless, which is very humiliating for a hunter. Bitcoin saw the identity card of many people being stolen and stolen in such a way that there is no scope to get it. So hacking is and is very easy.

Hacking bitcoin is something that is impossible for others to do. Because some technologies such as Open Source are very helpful in maintaining the integrity of bitcoin. Plus bitcoin is very centralized with Blockchain technology. But you must remain cautious and protect your assets by being smarter in everything you do.

of course that is very possible. because bitcoin makes the internet as a means of transaction, it is very likely that bitcoin will be hacked.

As far I know bitcoin is the most secure system but the fact is it is also run through internet and those things which is connected through internet can be hack.

Yes We use Bitcoin because its safety in the first place and that is the significance of its build blockchain technology to be untouchable or get hacked by anyone in the world and so far this is a great currency in the crypto world to do transactions without worrying about criminal attacks.

Some say Bitcoin is very likely to be hacked even it uses blockchain technology and like many systems that run upon using Internet getting hacked the same thing can be happen to Bitcoin and its wallets but according to my understanding the basic build algorithm or the technology behind Bitcoin network is far more sophisticated to hacked or interrupted by normal hackers or otherwise considering today criminal activities those hackers do Bitcoin wallets should already been hacked by such criminals but there is no news we hear like that

It is possible only when the user become careless about the security of his wallet otherwise it is impossible because it is the safest system.

You can hack Bitcoin or other crypto users, but hack Bitcoin its impossible...

The author, very informative you have's accession...
As for the main issue. As far as I know, I read online that only a quantum computer able to crack the password to bitcoin and, accordingly, to hack bitcoin. And so it is almost impossible. However, many hackers manage to break not bitcoin but the exchange. Because the exchange is not the blockchain and the code of the programmer, which can be vulnerability.

I have read that the bitcoin network can not be hack, as hacking it requires all computer system upon which it runs, and these are in millions, that it's too expensive to take such adventure. Although individual wallets can be hacked if not properly secured or exposed due to compromised.

Yes, blockchain itself can't be hacked or maybe no one will interest to hack since it only contain records and process of all crypto related.But wallet and exchanges is hackable and most common thing that our wallet that contain bitcoins compromise ia when we don't take care of it or we don't have any basic defensive move to avoid being steal

I know in some occasions where exchanges got hacked by hakers to steal cryptocurrencies and in those scenarios the damage was very bad and the entire token holders had to bare the losses but hacking Bitcoin network seems like not realistic and many maybe tried and even trying at the moment but so far we can agree that it is not possible but know knows what will happen in the future

mostly what ever has on the web can be hacked because there is no vulnerable in web, but you can prevent it by using extra securities and like 2fa and other authenticator.

does this mean it's all unsafe? :o

This to some people seems to be impossible, but there is a component that uses a piece of software besides Bitcoin's secure surfing network to spoof transactions. This has a huge impact. to investors and that is why people see bitcoin as a bankruptcy. Since we have not found a way to deal with fraudsters, hack. We need to be more careful.

You'd have to contribute around 3billion dollars constructing a specific server ranch to endeavor a 51% hash attack. If anyone did that it would destroy confidence in the asset and the heist wouldn't be worth any roi

Bitcoin is succeeding today because of its security, because of its encypted  peer to peer transaction i don't think it would be easy to really hack bitcoin, i have not even heard a single attack on bitcoin, u cant hack its AI, the only way hackers i think succeed to get some btc for them selves is by hacking an in secured Exchanger. for bitcoin mmmmmm no way.

I think it is impossible to hack bitcoin, as part of the block system of the system, or at least very difficult. And hacking a purse to store bitcoin, it will not be difficult for a team of strong hackers. :D

It is not impossible, hacking Bitcoin is possible the only thing that stops this possibility is the fact that there are no powerful computer that can match up the hacking that will happen, I mean we need a powerful computer to hack the Blockchain or Bitcoin itself.

That is the reason why there are some questions like what will happen if Quantum Computers are now available to our world. What will happen to owners and investors of Bitcoin but I guess Bitcoin will be developed at that time so there will be no problem.

until right now I don't know how to hacking bitcoin transaction, or wallet, we can see that the wallet of bitcoin is using the private key, and the one private key and other private key don't have the pattern, to hack it it will very immposible because you need to arrange many character and number into a private key,

hacking bitcoin is impossible. hackers can hack exchange sites or by phishing information but they cannot hack bitcoin.

Bitcoin is known for its security since its code based and its exchanges is distributed and scrambled its extremely hard to hack bitcoin however programmers assaults on trades and different wallets and they take bitcoin from that stages yet at times we find out about hack the bitcoins from that trade then this is the certainly frighten us since its an innovation and it tends to be Breakable.

Great point here bro! Bitcoin cannot be hacked but its storage can be. Large cruptocurrency exchanges had been hacked already. These hacking were once the cause of bitcoin price down. Bitcoin wallets can also be hacked. So far, these issues are still hanging in the cliff until exchanges and wallets are fully secured.

Everything think is based on internet can be hacked but the question is how difficult it to be hack and as far I know bitcoin is the most secured zone so, it will become very hard to do so.

I'm a regular bitcoin user and I always try to be updated and till now I don't get any news related bitcoin hack because it is very safe.

I thought Bitcoin hacking is impossible and I do think the same way but many say there wallet got hacked but those things has only happen to few people and the majority of people who use the Bitcoin network doing fine which means some are not following right practice during handling and using of Bitcoin wallets and the network and that gives hackers an opportunity to hack there wallets and get the tokens   

Security has been always an issue in the internet world so hacking bitcoin is not impossible. It's internet related so it's really possible to be steal from us. Well as long as we are taking care of our own account properly then we are assured of its safety. Nothing is impossible for those people who really wants to get something.

I think its all safe.i m regular bitcoin user i always try to updated any news related bitcoin hack because it is very safe.

Yes hacking bitcoin is possible because they need only to get the information that they need. Actually hackers get first the trust of someone and they will use it to hack it

yes what you say is true, bitcoin hacking for now is impossible but it does not rule out the possibility, with the growing world of technology, and bitcoin does not develop its security system in the future there will be people who can hack bitcoin.

As far as I know. it is almost impossible to hack bitcoin. However, if attackers have more than 51% of all mining in one hand, bitcoin becomes vulnerable and this is a problem. By the way only a quantum computer could crack the wallets of the bitcoin brute force keys

As far as I know the hacks that have been made until now are due to the users who are not very careful with their passwords and accounts as well as the exchanges. But the blockchain was not able to be hacked (P.S correct me if I am wrong)

Possibility rate is low. Hackers only get access to users wallets when users are not careful with their pkey or involve in browsing on some phishing site by clicking phishing link. So with user not been careful hackers can operate on such person account but if user is careful then they can't be any way for hacker to work.

Lots of bitcoin has been hacked due to putting your info on the unsecured sites. And hackers can also steal BTC by stealing your cookies. These are the basic techniques which hackers use for stealing your money. Also be aware of phishing sites, and keep basic things in your mind. Stay Safe

In the efficiency and legit bitcoin that can provide profits it is possible for hackers to do what they want just to hack to earn bitcoin.The solution for that is keep safe and have privacy to your wallets.

Even though our technology our security system is very hard to penetrate because of some updates others also upgrading their hack tool to penetrate the system. IT is an never ending battle of the greatness. It is very easy for them to hack it if the security system is poor but they really put budget on it then it will take long time for them to hack it. Also make it sure that your computer is safe to use.

Of course it is very possible that bitcoin and other crypto currencies are very vulnerable to hacking because it uses the internet that is used globally

Hacking bitcoin wallets theoretical can be, but it need huge amount of power what makes this hack not effective.
You send more power of electricity and time then have profit from hacked account

take down all asic machines .. no transactions can be confirmed then

there's no imposiible for the hackers. if they want to steal your account they do it. but luckily the professional hacker not doing this thing they only monitor those scammer or what we called fake hacker. the hackers doing not bad or crime activities. they only sucure the important site. and they make the world peacufully in the digital world

Everything is possible on earth.now in the world there is a lot of advances technology.so it is possible to hacking because it uses the internet that is used globally.

Yes is it possible if you trust other. Actually the worker that experiencing scam or hack is the newbie because they wanted help but some people wanted only to get their trust and use that to get what they want.

no always need to get the trust of someone, just simple access to his computer will do. There are many ways how to scam and hack, it's important to learn defence against these attemtps.

Very possible can bitcoin hacking because now there is a lot of digital technology in the market.bitcoin does not used globally it uses the internet that is used security system.everything is possible the only reason hackers is very strong.so i think you will be very careful.

no bitcoin to hack is simply unreal. he can stop working and disappear only if worldwide light switches off the light, but if this happens then the whole world will actually be lost

This is not new we all knew whats the capacity of hackers, even the small amount they interest it how come bitcoin can aware, there is no possible for them because bitcoin is the largest digital money in this world so more get intetested with this..

No  don't think the hacking of bitcoin can ever be possible,  if not it could have been hacked earlier before now.  I have been hearing about how other coins have been hacked but that of bitcoin has not and never been hacked..  Its only exchanges that can be hacked and some BTC can be moved from it..

I do believe that the bitcoin network itself remains to be hack proof til date. The cryptography applied to every wallet and every transaction and the peer to peer method of confirming and recording of every block is super strong. There is no effective way of injecting dubious transactions nor trying to redirect a transaction to another wallet to steal bitcoins.

News of bitcoins being stolen did not originate from the bitcoin network itself, rather, it is the exchange or the bitcoin owner themselves that gets hacked. It is in this event that attempts to steal bitcoin becomes possible. But never over the network of bitcoin.

"Hack" bitcoin is impossible, even from a technical point of view. The only thing that can be done is to carry out an attack of 51%, but bitcoin is protected from this.

Hacking Bitcoin is impossible.  Hackers can hack exchange sites or by phishing information.  Bitcoin is really famous for its safety.   ;D

There are so many intelligent people who just use it for bad doings like hacking a system that is not their property. It is possible that bitcoin can be hacked by anyone if the system of bitcoin is not secure. But i think they secured it because money is involved. I hope bitcoin will not be hacked even in the future.

It seems impossible if bitcoin is hacked, because the amount will not increase and decrease. except what can happen is a hack against a system related to bitcoin such as wallets, exchange and trading services.

In my knowledge it is impossible to hack bitcoins only the bitcoins wallets can be hacked if they leak out their private keys or clicked the phishig link.When the bitcoin is in the transaction no way to stop it even the user who created the transaction will not be able to stop it.

There's a lot of programmer are genius by hacking account open very important files technologies now a days is a huge amazing so there's not impossible to hack bitcoin easily specially to the people are not read the any spam link website directly log in your account to steal your personal password and email etc.

You can steal it, but it's impossible to hack the technology itself.

Hacking Bitcoin is impossible because it is processes upon the blockchain technology and most of the scenarios when some one got hacked it is due to his or her carelessness to protect important information about there accounts in exchanges or digital currency holding wallets but once they lost there currencies to a hacker they point errors in the Bitcoin system and its network I think that wont solve the problem   

Well.  It isn't that possible to hack bitcoin without wallet,  a key and password that is why you have to be careful of those handling your key and password. Never trust anyone with your key.

Hacking into  the blockchain technology is pretty difficult and it's no child's play. In my very opinion I think the platform is relatively safe and secured.

It is impossible to hack Bitcoin Network because you need Millions of dollars to do it and the probability of success is so thin that even a Billionaires cannot afford to lose. The only thing that the hacker can do is to hack the sites and phishing, but hacking a system  network of Bitcoin is impossible.

It can describe by those who are used to hacking but it is now very easy that some one providing internet facility services and then they copy your data and they access your wallets and your important information now hacking is very dangerous in present time.

it could be if indeed someone was able to do it, but for some cases it was still hacking a bitcoin wallet that indeed many thieves are now targeting bitcoin because the price is really big...

I think hacking bitcoin is hard because it is very safe. As long you know the right address to enter and you always keep your account and password by your own. I am sure that it is very safe, let just be active and knowledgeable enough to whatever decisions we make.

bitcoin hacking should not happen because I see the security of blockchain and bitcoin technology which is cryptocurrency and digital currency so it should be very difficult to get hacked.

Actually Bitcoin hacking is not possible without current technology,and wallet information.hard password,save key,2FA verification it's killed not possible.but if hacker will get your wallet information then hack is possible.in just my opinion so I don't know another reason.

Most hackers stealing bitcoin from exchanger. Hackers almost impossible hacking on bitcoin wallet as long wallet holder keep their private key safe. Exchanger wallet vulnerable to be hacked and thats why many expert said better store our coin in our own wallet

Virtually impossible hacking Bitcoin. The blockchain system itself is configured so that it is not possible to rename records.

Hacking blockchain network is so hard, and hacking biggest blockchain network is impossible, in my opinion.

From my point of view, it is extremely difficult because bitcoin is developed with blockchain which is famous for its security

We all know that bitcoin is a decentralised crypto currency and thus there is no such proper authentic regulating body over the bitcoin who could keep eye over all the illegal activities of bitcoin like selling drugs, explosives, money laundering etc and then second thing that is promoting the illegal use of bitcoin is that its transactions does not involve any third party seizure and thus no third person could see the transaction between the two and thus two illegal parties can illegal transact without any interruption of government and thus leading to illegal use.

if someone try to hack a bitcoin blockchain, it's certainly impossible to hack. but the most vulnerable to hacking is phishing activity

I think it's impossible to crack bitcoin. Breaking of wallets, the abduction of cryptocurrency is possible. There is a case of hacking exchanges. There is a danger in any case.
