so is that can happen that a hacker can hack btc wallet??

maybe, a person should have expertise that goes beyond the creator or developer of the wallet. in essence, it is not easy to break through an online-based system. although I agree, everything related to the virtual world can potentially be hacked.

issue of security has been a fundamental one for bitcoin since its development. On one hand, bitcoin itself is very difficult to hack, and that is largely due to the blockchain technology which supports it. As blockchain is constantly being reviewed by bitcoin users, hacks are unlikely. On the other hand, though, the fact that bitcoin itself is difficult to hack does not mean that it's necessarily a safe investment. There does exist potential for security risks at various stages of the trading process.

No.. how would it be hacked? it is impossible to create a copy of a bitcoin or a crypto asset if that is what you are talking about.

The only way in that you can be "hacked" is that if someone gets your Private key from a pishing site, because of your exposure, or because you might have a malware on your computer and you do not have a hardware wallet.

That is why a lot of people prefer to have a hardware wallet, because you are never going to be hacked because of the huge security that they are offering (you need to press a button in order to confirm a transaction)

Not quite. The possibility does exist that Bitcoin's algorithm can be vulnerable. The chances of it being vulnerable and exploited, however, are extremely low based on our mathematical understanding of hashing algorithms such as SHA-256. It would be irresponsible to say that it is completely impossible for it to be "hacked." Looking back at vulnerabilities in previous security protocols such as WPA, which was the standard years back for wireless access points means that you should never be overconfident on the security of any one protocol or algorithm. There always exists the possibility that it could get cracked or compromised in some way. Bitcoin should not be an exception to this kind of thinking, albeit I am arguing mostly about technicalities.

Let's be real, you're discussing a possibility of something happening, although nobody has ever done it and nobody has ever shown a way to do it.
It's like discussing landing a ship on the Sun's surface. It hasn't been done, noone has ever come close to doing it, it will most likely never be done, but theoretically it's possible provided that you had some sort of force field shielding. Grin

While I see where you are coming from and you are most likely right in that we will never see Bitcoin be hacked, my point is exactly that what you said about landing on the sun is the same that people thought when WPA got compromised. The same goes with vulnerabilities such as Spectre and Meltdown for processors discovered in the recent past. Everyone thinks it is completely impossible-- until it actually happens. Again, you are probably right, but it is also important to consider other possibilities.

You were also right about the spammers...

Sure, A wallet can be hacked if the user don't take good security measures.
A good hacker can easily gain access to a newbie PC and steal his private keys.
Easy measures can keep you safe like 2FA, email verification, sms notification and a strong password, never trust freewares and do not open suspecious websites.

If the complete online wallet server is trying to hack the bitcoin from the wallet. Still it is possible to hack the wallet you are using. So keep the fund always in the private key secured wallet and keep your wallet.dat file in your private location in your computer or elsewhere.
To say exactly using online wallet is not at all a perfect way to keep safe your wallet. You may here about the nice hash server. If they attacked your wallet company server, you have bear the lose no one will be responsible for it bro. You can read wallet provider norms to understand it.

There are already a practice on how to get secure your computer just in case someone would like to go into your network or someone putting a malware to your computer. All you have to do is to learn it from the expert, search everything on the internet or ask for an advice to any professional if you don't know anything. Prevention is better than cure, so start it with yourself and then apply.

the network as a whole.. no

you personally. yes

basically no one can just take funds from the blockchain by manipulating their copy of the blockchain.
but people can target you directly by hacking/accessing your computer and taking funds from you by using your keys

The question has been answered in full in this post. The rest of you can quit spamming now.

This is something that many investors are concerned about, which may have led many governments to ban Bitcoin, because Bitcoin is still dependent on the internet and the risk of hacking. The attack on the BTC network is very high

I think all have a chance of getting hacked. technological progress is also followed by the progress of how to surface a bug of the system. but the more danger for now is the exchanger.
somehow but I think some of the end of this month a lot of news about the rise of hacking events that target the exchanger. that is why we should be more careful in save our assets. would be better if enabled feature 2FA on exchanger. at least it will minimize our wallet being hacked

Currently, no individual or organization can hack the SHA-256 algorithm, encryption algorithm for electronic Bitcoin. It is only when a quantum computer is born that the algorithm SHA-256.

I think so. Since it's on the internet, while the technology improves as the time goes by it also increases our knowlege on how it works. People who are eager to hack can always make this possible. Just try to secure everything that is supposed to be private.

Every digital things should be hack easily. But Bitcoin is not easy to hackable. Because you only know about the private keys. If someone is hack your account is not possible. But only one way is possible some one use your desktop. It will easily hackable in your account. This is the only way to access your account. Otherwise BTC wallet is more secured in any other digital things.

Maybe in 10years BTC can be duplicate but it needs a quantum computer to do that thing,but today quantum computers are not yet invented.
