3% of 0.5 ETH or 3% of 1000 ETH?
3% of the 1000 ETH, every one gets 3% of the money they invested.
Every 25th investor earns 9%, that is the jackpot position.
This is wrong!
If I deposit 1,000 ETH right now, and then deposit 0.05 ETH 1,000 times from different accounts, my 1,000 ETH deposit will have been paid out 3% 1,000 times, or 30,000 ETH. Where is this money coming from?
Assuming my 1,001 deposits are the only accounts in the piggybank, that means only 1,050 has been collected yet 30,000 + %s for all the 0.05 accounts are being paid out.
