Any real proof that actually we have chances of winning it? How do we know you won't just "give" them to your own addresses? How can you prove the system gives everybody automatically a equal winning chance?
Every email and BTC address has it's own number in a list - every day there will be 3 winners so 3 random generated numbers and since every email and BTC address has it's own number we will know who is winner and we can send BTC.
