This is the first site that offers interest for your Bitcoin deposits. You will earn interest from unsuccessfull burglary attempts to your Bitcoin Vault. You can design your own vault security, and so reduce the possibility of burglary.
On this site, stealing bitcoins is now made legal: You can try to rob other users' bitcoins by guessing their vault password phrases by using the ciphered versions of them. Knowledge of cipher algorithms will help you, but you may also benefit from luck as after each guess, the system will tell you how many correct charecters you entered.
