Ponzi Idea:

Hey guys - to keep the rounds going for longer, how about this;

0-49 Deposits - Payout is 115% (Super Easy!)
50-99 Deposits - Payout is 120% (Easy!)
100-149 Deposits Payout is 140%
150+ Deposits Payout is 160%

These will hopefully encourage players to carry on depositing to achieve the larger payouts?
