For the amount that is involved, he should be able to have the ability. These kind of operation (ponzi model without liquidity to pay investors without more investors investing) always  pays smaller amount to maintain image and get more potential investors. They will try to keep feeding the smaller fishes to get more big fishes and keep it going until they can last.

Once you realized you are involved in a ponzi time scheme, best to play like small fish and pull out slowly little by little without creating any panic. It is selfish but it just boils down to if you prefer your money back or warning everyone. I will always choose to get my money back before warning everyone because if i warn everyone, the company still runs with everyone's moeny.
