Perhaps you don't understand what is a ponzi scheme. A ponzi scheme is a operation that pays you with the next person's deposit. They will pay you till people stop depositing and they can run away with your money or just don't pay you. Either way, you lose money.
This. First they build trust, then they pull the trigger. Thats what Karpeles and every other exchange did.
