This system is using yesterday's deposits for pay to members today. I will explain it with an example; if yesterday Ethmin got 200 ETH deposits and today members can cashout 250 ETH, system rating this two value and paying all members %80 of their cashout request, and %20 of cashout request returning back to cashout balance to withdraw next pay period.
