Lost my bitcoin

[Dudeperfect]

That's what experienced members are shouting for everyone who is holding their funds online. Even if someone is taking all the security precautions such as 2FA and other safety features, there is a risk of compromisation of the database on the server side.  Thus one should never maintain more than his 5% to 10% holdings on the web wallets or exchanges. Reputed hardware wallet or securely generated paper wallets along with backup is the best option in my opinion.

Sorry to hear this news of you.I always suggest people to use a offline hardware wallet.And keep their online wallet password/private key very safely so that they wouldn't face problem.And thanks for your advice

[Apriand]

OP, sorry ti hear that and thanks for your sharing. Currently i still use my email to save my login data to many site. Now, after i hear from you about that i'll move all of that to offline. I'll write that on the paper to make sure all be safe. Once again, thank you very much for sharing your bad experience.

Hello all, I been a long time reader here but have only recently signed up.
I started mining bitcoin in 2015. I saved up and brought 2x second hand s3 antminers and a 1x s1 antminer, I was really interested in the blockchain tech and had to have a piece of the pie.
I mined just over 4btc which had been sitting in my blockchain.info wallet. One day I couldn't access my email due to wrong password, I finally got access back into my email and noticed a few emails had been deleted as well as the one which contained my wallet details, lucky I had a .txt backup. Urgently I log into my wallet and found I had been a robbed, all my btc was gone. My heart sunk, I feel so bummed all that work and money for nothing.

My advice is
Dont keep you wallet details in your email or online at all.
If you have bitcoin dont tell anyone
Use an offline or physical wallet

Dont make the same mistake as me  

Oh no,it is very hard to digest because 4BTC is really big amount with the current value,but if we are having more than one bitcoins it is better to store it in a hardware wallet and never store your passwords or wallet details into mails or google drive even not in your system just keep it in a pen drive and keep it in a secured place.But don't worry you can make more bitcoins than you lost by working smartly,try to do trading with your mined bitcoins to get extra profit.And try to do altcoin trading which give good profit with less investment then you just but bitcoins with the profit from altcoin mining.

I recommend using a secure hardware wallet when you have a large amount of Bitcoins. Also a paper wallet but keep the private key in two separate and secure locations. For example a bank lock box.  You can rent them for a monthly fee in some banks.

If you must use online wallet (like such as say Block Chain) my advice would be:

1) Sign up with a brand new email address, tell NO ONE of this email address and never use it for anything other than correspondance to your online wallet provider.
2) Ensure both your online bitcoin wallet and email account has extremely long secure passwords
3) Enable 2 factor authentication to your phone and any additional secondary password for sending bitcoins from your online wallet. Again, ensuring that nothing ties your phone number to the email you used to sign up for your wallet by having a brand new one.
4) Keep any computer or mobile device you use to access it clean from malware and viruses, if unsure, dont use it.

I am very sorry the OP lost his money. I concurr that all those points are very important and I want to stress that number 4 is no less! People use their normal phone (a smartphone mostly these days) as a 2FA device. It is wrong! It is very easy to hack a smartphone. People lost their money from a 2FA protected online wallets, too, because of this.

The good practices are the following:
1) I know people who have a dedicated computer for their bank accounts and never use it to browse other web pages. This is a very good practice. Use it for BTC too
2) Also, you may want to buy a very cheap and simple phone and use it ONLY for 2FA just to be able to read text messages with a second factor passphrases. Remember, the simpler the phone, the harder it is to hack it!
3) Or, as the alternative, buy a hardware wallet, it can be used both to secure your bitcoins but it also features a 2FA device. A very secure 2FA, to be sure.

It was really unfortunate for you to lost that much bitcoin, this will be one the lesson learned for all of us using bitcoin.
I dont keep my private keys online or in my email, i always back them up offline and i put my bitcoin in an offline wallet for more security.

It is NEVER a good idea to store wallet data in online services or cloud storage. We have seen time and time again, how these services are hacked and how people lose their bitcoins. You have to remember one thing, these hackers cannot hack Bitcoin, so they focus all their attention and resources on the weakest link, which is third party service providers that use Bitcoin.

They get easy access to centralised services with poor development and code with a lot of exploits. Nobody has ever lost bitcoins, stored on paper wallets. ^smile^

[theblack_cat]

thanks for your advice sir, but it's all back to each other, because the mistake is done by each person because I also
never experienced it ie lost bitcoin in my wallet online even though the amount is not as big as have master ,,

[bitcoindusts]

Sorry for your lost OP, that really was a huge amount now compared to the price when it was in 2015.  This is the first thing I learned about saving Bitcoin. There had been many warnings and alternatives than keeping our BTC in an online wallets.  So the first thing I did was download a light wallet and protect the address with a password.  I also set a back up of private keys just in case my HDD/SSD fails.  I hope that many member here will learn from your experience and thank you for sharing and giving us warning about this kind of stuff.

I have a friend who also lost his btc due to it was hack his wallet. A victim of phishing attack in his email that is why it is very important to be very careful in saving our details to not put or save it in an email. So sad to hear the story of others.

This is purely your fault, your experience of being a valuable sharing for us always keep our financial data especially bitcoin in a safe place.
Email access is one of the most vulnerable data to hack or missing, it is not recommended to save the important things in it.
Regarding your case, bitcoin certainly can not be in reserve, because it is so independent that there will be no one party that can save your account and transaction, except your own.

[bluegreen9]

It is one of the disadvantages of bit coin. If you have security issues and only a few numbers are leaked, you can not lose access to the link because you can lose everything you have.
