Topic: Bitcoin Security - page 6. (Read 1996 times)

I haven't bought it for now, but I believe it's very good to use, and also has the potential to be used in the future.

Cryptography controls the creation and transfer of a cryptocurrency, and the protocols underlying bitcoin have proven to be robust. ... Bitcoin exchanges are not regulated by the government, and they generally do not provide enough insurance and security to be used to store money in the same way as a bank.

Basically bitcoin is a cryptocurrency, so it will be very secure because no one can get the key of your bitcoin address.
What you need to do is take a caution when you want to use the key for transferring your coin to other address, hackers can phish you to get your key.

First, this are the kind of posts and discussions the community need to see more. Every steal truly hurts Bitcoin and people tend to associate the lack of security in exchanges to the security level of Blockchain itself. However, Blockchain technology is extremely good but it can be improved and it's something we could be thinking about - About the possible implementations it could have in our everyday life.


This are good steps, but they are the beginning. It's important to:

Keep your coins inside your device: Unless you're trading and you need to have only the needed amount there, the coins should be always kept in wallets within your own devices - So the private keys are securely owned by you. Unless you're confident about the security practices of some website and it's better to research.

Use hardware wallets and cold storage: If you have a decent amount of Bitcoins this two methods of saving them are extremely good and secure unless you let third-parties with bad intentions be near them. Besides the few coins you left in an before mentioned wallet and/or exchange for trading - The rest should be stored with this kind of technology.

Check your devices security: Security is something you'll always need, it's needed in everyday life. It's better to be sure that while using wallets in a desktop/cellphone/tablet the device itself is secured so your private keys are secured too. Make sure that you choose a wallet that encrypts your wallet file, so in case of emergency it's not so easy to access it.

Bitcoin security depends on a person only

Yes in my opinion if only relying on the security of the wallet alone is not enough to keep your bitcoin, I suggest using a hardware wallet for additional security, and also using complicated passwords so that they are not easily hacked.

Looks like people really are not answering your question and just typing out random shit.. pretty sure it's for airdrop bounties.. It's only as secure as you want it to be.. do you due diligence, make multiple backup's of your private keys and keep them in cold storage. This is your safest bet as to keeping your BTC safe and secure. Mobile wallets and your own PC can be targeted. Ledge S Nano works great but if you don't have the money to throw at it.. use a paper wallet but ensure to keep multiple backup's just in case. Personally I have two other family members holding onto copies just in case anything happen's and my family can receive it. Anyways best of luck, don't share your keys.

Bitcoin is one of the most secured blockchain in the crypto world. Since I was introduced to crypto I have never had anything like hacking bitcoin which makes me to always recommend it for long term investment. But you need to play your part when it comes to security keep your private keys safe and aviod airdrops don't mistakely use your private keys instead of wallet address with this ideas I believe your funds are save 2FA is very important in you accounts.

Stay away from these USB password protectors. If you want real Bitcoin security, invest in some hardware wallet like Ledger or Trezor or alternatively use paper wallets to secure your coins. I have been securing coins in hardware & paper wallets for years and I have not lost a single Satoshi.

Do not over complicate issues with things like USB password protectors. There are malware targeting the firmware of these USB technologies, like BadUSB, so it is exploitable. 

Bitcoin's system is secure I think. Because everyday, isers increased and also the investors. I'm pretty sure that they are working in it when there are problems in it like hackers want to enter. Something like that. This is all about money so they must secure their systems. Especially when the price of bitcoin rise up to million.

bitcoin has many ways to protect accounts from hackers. because bitcoin has an account that only we know. and we often open it to invest. so it's safe always if we always check it.

To secure your money use the offline wallet which one of my friend was using it also just like what you said it is similar to a flashdrive that using a many password or  the verification to secure your coins. Securitu was most importance so that we need to care our money to those greedy people that they to get our coins. It is better to use offline wallet that online.

If you are running any kind of Bitcoin online business, offline wallets will be a better tool. They are way safer and they are not that attractive to hackers. If you really need to make use of web based wallets, try to keep some of your Bitcoins on an offline wallet, or a cold wallet.

Bitcoin in present times is the most successful and the most popular crypto currency of all and not only this bitcoin is now considered as a threat to Fiat currencies and there are even assumptions that it would even replace the present Fiat system and the most important feature that has made bitcoin so successful is its safest and the most confidential transactions that has made millions of people to invest into it , as it transactions does not involve any third party seizure and provide user anonymity so bitcoin is the safest of all the investment.

yes, what you mention is a pretty safe way for bitcoin security, but if you want to improve security, you can use a hardware wallet, because the hardware wallet has a high level of difficulty to be hacked.

To be honest i am fine with the online wallet paired with a 2FA enabled mobile app (perhaps the method being free appeals to me much).

Hardware wallets are good too. Some people prefer this method of securing their bitcoins but comes at a cost, and at times, hefty too depending on the features and brand of reliability too.

But should you like to try it out, there are some considerations to take. Primarily, how do you plan to use it? Is to for mere storage? Or you want to use it for frequent payments? Varieties of hardware wallets are there. I suggest learning more about hardware wallets before buying one and pinning down how you wanted to use it.

of course bitcoin has a very good level of security, hiding personal accounts until no one is able to know other than the owner

It is best to use Ledger.The only rule that should be followed when buying a Ledger is not to buy it on the black market.My friend bought from a stranger and lost about$20,000.The thing is that a stranger entered him some chip that helped him to take possession of the private key of the owner.So be careful when buying.

Yeah but everything have their own risks especially if the person holding the wallet isn't careful. You may not lose your wallet to online theft but if as with a physical wallet, once you lose your hardwallet, you lose all your btcs as well for good

A security of 128 bits is impossible to crack with normal computers, so normally a public key is enough distance from your money and the thief, however it is not quantum computer resistant. Quantum computers don't exist yet, but when they will, it will be able to crack a public key and reverse engineer the private key from it.
