How do you make money to pay us interest?

Your account is now also a bitcoin savings wallet!
Receive compounded daily interest on any balance that you hold in your account, without doing anything.
All you need to do is maintain a balance of at least 30,000 satoshi (0.0003 BTC) in your 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 and your balance can be withdrawn any time you wish.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 account like an instant-access savings account to hold your excess bitcoins and earn passive interest on your account balance everyday.
We also pay you 25% referral commissions on any interest earned by your referrals!

When is the daily interest credited?
We 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.
How do you make money to pay us interest?
When you hold money in your account, we split it into 3 parts - the first part is used to cover user withdrawals, the second part is used to bankroll our MULTIPLY BTC game and the third part is used to expand our bitcoin mining operation (which is currently 9.065Petahashes or 0.010% of the total hashpower of the bitcoin network). We make a profit and assume the full risks of our businesses and in return for you saving your money with us, we give you a risk-free fixed rate of return.
