Topic: Bitcoin is 100% safe? - page 5. (Read 3927 times)
I think so that Bitcoin is safe. I never doubt the transactions done in every single day, I trust it. We can say it is very safe because of its security and of course also the proof shows publicly on the ledger. I never heard some kind of hacking...
yes. someone managed to create 184 billion extra bitcoins before it was patched. this was back in the extreme early days when it was only satoshi and a couple of other people working on it. since then thousands of people have examined the code and come up with no serious flaws.

Has the bitcoin system ever been hacked until now? Is there any security vulnerability in the Bitcoin system up to now?
Honest nodes provide all the security measures needed.
Yes, I know that. There was even a little talk about the subject. https://bitcointalksearch.org/topic/network-sent-datas-1738678
But is it possible that the protocol I am wondering about is hacking itself?
Bitcoin is safe. But not really 100% safe. Bitcoin AFAIK is vulnerable from DDOS attack. Other than that, i think theres nothing more. Also its up to the owner how he/she take care of his/her bitcoin. Keep in mind that no matter how safe is bitcoin if the owner is not careful with his/her bitcoin. Bitcoin is not safe. The owner should be responsible keeping their bitcoin.

The bitcoin protocol has never been hacked and no funds have been stolen from the system, the problem is when 3rd parties dont secure the private keys to their customers bitcoins. these are the hacks you have heard about over the last few years.
Yes exactly these protocols were great because its has a stealth character which cannot be hacked. Most of those problems like stolen funds were on their personal online wallet leaked with other users who became untrusted who betray their coleagues and get funds from them. Bitcoin itself is safe because its a digital form and it only became fear ot theat due to fiat cash convertion.

The bitcoin blockchain system itself is pretty safe against hacking, as it does not rely on any central authority to keep data safe from manipulation or spying. All transactions are visible, and the record of valid transactions is secured by the block confirmation system (mining). There are attack routes (most famous is the "50 percent" attack) but most of them are academical and do not pose a real risk.
I don't have a complete overview of bitcoin history, but I think that the "hard fork" of 2013 was probably the most critical event in that it caused transactions to be lost after they were thought to be confirmed.
However, there have always been cases where human mistakes or badly written software have caused loss (or theft) of bitcoins:

However, there have always been cases where human mistakes or badly written software have caused loss (or theft) of bitcoins:
- Users might forget their password, accidentally format their hard disk etc.
- Wallet software on PCs might be vulnerable to trojan attack targeted at bitcoin users, revealing user's private kease to an attacker.
- Badly written wallet software might use not-so-random random number generators when creating private keys.
- Exchanges may be vulnerable, allowing attackers to manipulate their account balance within the exchange and then withdrawing bitcoins.
- Any business handling bitcoins might be hit by inside jobs, which can also involve hacking of computer systems to keep the theft undetected for some time.

We can't say that bitcoin is 100% because even though it says that it can't be hacked then there is still a chance of being stolen of our bitcoin like the previous hacks on exchangers and online wallet like blockchain, So i think that bitcoin is not 100% safe. There is no 100% safe on the internet.
You should be far more concerned about how much you know about Bitcoin and how safely you behave. It is so much more probable that you make a mistake that will result in the loss of your Bitcoins then a technical issue.
