Receive compounded daily interest on any balance that you hold in your FreeBitco.in account, without doing anything.

All you need to do is maintain a balance of at least 30,000 satoshi (0.0003 BTC) in your FreeBitco.in account and we shall pay you compounded interest on your full balance everyday. There is no lock-in period to earn interest (you start earning interest right from the first day!) and your balance can be withdrawn any time you wish. Treat your FreeBitco.in account like an instant-access savings account to hold your excess bitcoins and earn passive interest on your account balance everyday.

calculate the interest on your account balance daily and credit it at a random time every day. If the interest would be credited at a fixed time everyday, people would be able to game the system by depositing before the credit time and then withdrawing after they receive their interest. To avoid this, the daily interest is calculated and credited at a random time everyday.
