Do you mean accounts with a negative profit? If so, you are creating an incentive for people to create new accounts whenever they have a negative profit. It wouldn't be in the player's interest to try winning back their loss on that account - better to make a new account and play there.
You are right.This idea makes no sense but i think JD should have reward system maybe based on wagered amount(you already creating stats for that) ? 25-50 clams out of 1200 daily will not hurt investors and should make site more attractive for gamblers.
