Our goal is to grow the Anonymity Set to 10,000 deposits so until that is reached we will offer a reward to everyone using the service. Each month we will allocate 1BTC to distribute between all funded Notes proportionally to their balance. Payments will be made every day and you are free to withdraw your deposit anytime. If the amount allocated for rewards is 1BTC a month that means 1/30 = 0.0333BTC will be distributed every day.
If the multi-sig balance is 10BTC and you have a Note with a 1BTC balance you will automatically receive 10% of 0.0333BTC every day you keep your Note funded, which is 0.0033BTC a day.
On second thought: this sounds a lot like the many "services" in the past that offered an interest on Bitcoin deposits. Usually, that didn't end well.
Are you sure you want to be associated with those?
