You made a lot of mistakes, the first one was to TRUST on a system.

You trusted Bitcoins-24, do you know who they are? Giving something of value to anybody is always a risk, even giving it to the bank. You are from Argentina, where you had a bank run on 2001, banks stole dollars from people, and the minister give the people "peso" instead of his dollars.

Then you trusted on BlockChain, even when they say they have security, you can't be sure if they really are keeping your coins safe. Misteriously they can say "uppsss, our system was hacked" and say "bye bye" to you (ex-) coins.

Then you trust on Yubikey, a third party security system. What happens if it fails? And 2-pass auth? The one controlled by G00?


The answer was always, do not trust on somebody, you should keep your coins for yourself. Cold storage, print the code, or remember it. And trust no one.
