according to the information I hear bitcoin is safe if we can keep the bitcoin passwords that we have. in addition I've also heard that bitcoin is not easy to steal because of high security.
Passwords of wallet? I just know as long as the hacker can rob your Bitcoin private key, they can rob your money. But, almost online wallets do not support private for user. Just offline wallet can own private by user.

no one perfect in this world, so there still a chance to get hacked / error. just make sure you don't carelessly put your account on phishing sites.
and make ur password strong and change for every 3 month *just suggest

But is it really? In a story titled “5 Ways Bitcoin is Stolen“, I took a closer look at various incidents of theft over the years and came to a simple conclusion: Bitcoin’s technology can be trusted so long as you know how it works, or if you rely on the right people. All of the thefts in recent years have been the result of carelessness on the part of bitcoin owners, or else incompetency or dishonesty from the companies they used.
The question is not about how secure is the bitcoin, but the real question here is “How much well aware are we about network security?” if we simply answer this question, we have no reason left to doubt about how secure is the bitcoin. All the incidents being quoted here are the ones which are the result of the careless attitude. If I want to secure my investments/tradings, I have to focus on the computer security and I have to adapt the best practices which are easy to find.

bitcoin is very secure yes, you wouldn't believe how hard it is to forge the ledger, however you're the weakest link in the chain. if someone hacks your computer and finds a way to your private key that would be an issue.

for right now i know that bitcoin is really secure, because bitcoin use platform that name is blockchain, as i know blockchain is the safest platform because every 10 minutes it will create 1 block and tell all the world about the changes, so if the hacker want to hack it they need 10 minutes before the new block is created

I think that Bitcoin is safe, as far as it's possible. It is unlikely that we will be able to find anything completely and completely secure. To date, thanks to Bitcoin, you can make secure transactions and quick international transfers. It works anywhere, anytime. Of course, there are huge risks. But there is a risk in any business or situation. The situation with crypto-currencies remains in limbo in most countries, the authorities are very ambivalent about Bitcoin. But people believe in Bitcoin and therefore are willing to take a chance, take risks. And as we know you've got to shoot to score.

It's not perfect, as others have already said, but if you study the types of failures that can occur in the Bitcoin ecosystem, you'll notice that these are problems with very low probabilities of happening, and most of them requiring astronomically high computational power to happen.

Bitcoins are really safe form of investment and it is well protected by blockchain.  Bitcoin blockchain is very secure that is why many companies started developing technology based codes into the new world. Another aspect of security are the safety measures is take good care of your personal password and private key.

IMO the Bitcoin Blockchain itself is very very secure. However, Bitcoin Wallets can still be hacked. It's best to use hardware wallets in storing significant amounts of BTC.

It is as secure as you choose to keep it. Consider it very much like cash in that once you've given it away, you won't get it back. The difference is that no matter how much bitcoin you have, it can be stored on 1 piece of paper. You can also store it offline in hardware wallets, or online in desktop wallets. There are a number of methods depending on how secure you want it to be. It's crucial to remember, bitcoin was designed to cut out the middleman in finance, meaning every individual becomes responsible for their own banking. Luckily there are plenty of options to enable this to be done with ease.

Hello pals,
Recently I introduced Bitcoin and cryptocurrency to my friends and family,they liked the concept but they asked me a question that I wasn't able to answer.Is Bitcoin really secure?What if a hacker was able to hack Bitcoin system/blockchain?Who manages Bitcoin security and what are the security measures taken to avoid hackers being able to steal Bitcoins?Why Bitcoin is not blocked for those who use it illegally by buying/selling in the deepweb market?What if governements ban Bitcoin because of these people?
I really appreciate if you  guys give me some answers

is bitcoin not secure why daily trading about 500 BTC ? why many sites accept bitcoin ? why more than 100,000 use bitcoin?

bitcoin is secure but must do basic things to save your wallet.

To be able to spend Bitcoin, the owner needs a special line of code called "private key". This line of code is stored in a "wallet" or a digital wallet. When it will be used, then the owner accesses the code and uses it for the transaction.

Private keys can be stored locally on the computer or printed with the printer. Problems arise because this line of code can be stolen or lost. When that happens, all Bitcoin associated with the private key will disappear forever from the owner's hand.

Yes, it's safe. But there are some people who always want to penetrate the defense in the exchanger, or create a phishing site. Well, there have been many victims, so even though it is very safe, we still have to be careful in using it.

 everybody speaks only to the technical security of bitcoin. Its financial security is another matter. As the boom or if you prefer “bubble” keeps growing, the prospect of a bitcoin collapse could do damage to many individuals, not least of those who are signing up for bitcoin-related IRA products (yes, it’s a thing and yes, it’s probably a terrible idea). Even more worrying are the warnings about how the impending bitcoin futures market may not stabilize prices as promised, but could end up contaminating the larger financial system.

I think that bitcoin is more secure than most existing financial services, including legacy banking platforms like swıft, which has been compromised repeatedly by hackers.

Bitcoin security does not rely on access control. Transactions can be conducted over a public network, cannot be forged, and cannot be modified once validated by several nodes on the blockchain. Transaction data cannot be used to resend payments, as the transaction is only good for those recipients who can unlock the transaction by having the proper key.

It's secure, but it requires a knowledge and care for this. This is not a game and the possibility of getting hacked is also possible in your bank account as well. We need to do our best to conduct our own safety and security in bitcoin.

Blockchain technologies may well replace many centralized models that are currently used, while volatility in the BTC price provides challenges and opportunities. Bitcoin technology is not anonymous to organizations with enough resources to determine how funds initially entered or exited the Bitcoin network.

As Bitcoin is a decentralized system, it pushes some security responsibility and control to the end-users, especially responsibility for securing private keys that are used to validate transactions.
