Am i understanding this correctly? If i paid in 1 BTC and that is say 10% of the bankroll, every hour i get 10% of what is in the bankroll until i have made 1.5 BTC?
No, I don't think so.
Every time anyone deposits anything, the whole deposit is paid out to previous deposits in proportion to how much they are still owed.
There's no "every hour", because each payout completely drains the scheme's funds until the next deposit arrives.
At least that's how I understood it.
