Is Bitcoin really secure?

[azisdoank]

yess...i think bitcoin is the safest platform to invest or saving purposes. Bitcoin is running based on a secure system. it has been created by some special codes which are still undiscovered. I think a group of a master is assigned to protect this system. some hackers were trying to decode this platform but they were totally failed to hack this site. the base of Bitcoin is very strong, so any one can believe Bitcoin easily.
in terms of security, Bitcoin has created an unimaginable example. if Government can ban Bitcoin there is another way to use Bitcoin. so no one can prevent using Bitcoin anymore.

I do not really think bitcoin is safe. It can be attacked by hackers. If you lose your password, all the money in your wallet can disappear. The risk is very high .. you face the hacker. As hackers become more sophisticated, they will have a way to trick your bitcoin so you have to be wary.

It depends how you to secure your account in your privacy setting and into your bitcoin wallet.

Actually Yes. Not even bitcoin, all currencies which are used Blockchain architecture are very secured. In blockchain architecture, we can identified following major security factors;
1. Public-Private key cryptography - Secure identities (Signature)
2. Hashing (SHA256) – Block immutable
3. Being distributed – Majority vs Minority
4. Prof of Work (10 min delay for a block) => Miners

However you should understand that, exchanges and wallets which are used in crypto, can be compromised. But not bitcoin or other crypto currencies.

Actually bitcoin is very safe all you have to do is give security to your wallet, Also protect and secure that transactions of it's users, But so far I think bitcoin is safe and comfortable, Just trust and believe on it, And I think a lot of people do like me.

Bitcoin is safe unless there are people who are careless enough to reveal their private information such as wallets and passwords. However, things that are on the internet are all considered unsafe therefore there is no such thing as absolute security. Just be responsible in every thing that we post and everything will be okay. Security starts within ourselves, don't rely on things that we can't handle.

Bitcoin is secure but the earlier wallets may be at risk if quantum computers come full circle and are able to do massive amounts of computations per minute.

Bitcoin has a modern security features, but hackers has a modern hacking features also so we dont know if bitcoin is safe from them. But in order to prevent that to happen, secure your coins in wallet that is recommended for its best service, and keep away your key from any other person unless it is your most trusted friend so that he can be the one to retrieve it when you are gone. Emcrypt your key in an offline software so no one can access it. Never trust anyone, aware scammers are around.

Is Bitcion really secure? Bitcoin is secured except for we that are involved in it. It doesn't required anybody help because you can do everything from beginning to the end

For me yes, bitcoin is really secure and safe and iam sure that it is depend on us on how we will gonna protect our bitcoin from the hackers and scammers, and my advice also to protect our wallet is we should used a strong password and and a verifued email .

For me bitcoin is secured when you're using a hardware to assured account being hacked. When you are using an online wallet you can set two authentication to highly secure your bitcoin so that no one can access you wallet that having bitcoins.

On my opinion base to what i have now bitcoin is more secured than banks. Because Bitcoins have two important security features that prevent them from being stolen or copied. Both are based on cryptographic protocols that are hard to crack. In other words, they exploit mathematical functions, like factorization, that are easy in one direction but hard in the other—at least for an ordinary classical computer.

Bitcoin is secured, the only thing you can do is to be careful. You need to pay attention in every moves you ought to do.
My advice is that if you have a chance to copy your private key in a piece of paper, well that's the best way you can do, so attackers could not get something very important in your computer. You can also use trezor in your transaction, for instance hackers will waiting for you when will you start to transact so they can locate your address, but by the help of this digital they could not go in to it.

In addition if you can make to memorize your Private Key, much better.
Bitcoin is safe. It's that the way on how you taking care of your wallet address.

What makes insecure bitcoins is hackers, because they will try to open your bitcoin wallet. Therefore, we must add security applications on our samrtphone or computer for example by installing google authenticator. So others will find it hard to open our BTC wallet.

It depends on your cryptocurrency wallet, before you start check the securty features and protocols. Review all the websites you've been entering, and the structure of your passwords. It all depends on your alertness if you care you'll be more secured.

[lautantepi]

Do not be confused with wallet security especially web wallets or online wallets and security of third-party services such as exchange with bitcoin security, The first is just cold storage or have malware on your computer that steals your private key.

[LindaFallar]

Well, still on the stage of knowing everything about Bitcoins. When my colleague introduced Bitcoin and its opportunity offered, I am encouraged by her to join in this cryptocurrency and transaction system. But sad to say, I forgot to ask her if bitcoin is really secure. So, I can't answer this question if Bitcoin is secure or not. For those who are experts here and to those who have wide knowledge already of Bitcoins, could share your ideas why we should trust Bitcoin or is Bitcoin really secure?

[Shishimanu]

Of course it is.
Bitcoin is the most secure crypto in this world.Also for that you need a high security wallet to store your Bitcoin safe

[mangkiko]

According to many sites one thing that makes bitcoin special is that it is very secure. The advatage of bitcoin is that it is very well secured and acknowledge privacy of the user. For me, bitcoin is secured since it has proven so many times but bitcoin can be a little off because of scammers and our clumsiness in sending BTC or money.

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

Actually, if we think about it, if bitcoin was not secure, it wouldn't have lasted for many years and until now it still accessible and the value keeps on getting higher. For me, bitcoin is the most secure of all the cryptocurrencies since it has already proven itself to be useful and valuable at the same time. This is why we shouldn't doubt bitcoin's security at all.

Bitcoin is safe until you keep your private key secret.

When your private key is leaked, then no one can help you.
