They have them convinced they will be paid on the so-called "guarantees" which is one of the first elements of a ponzi scheme. And they are already trying to devise alternative investments in additional unregistered securites through which they will be "persuaded" to "reinvest" the money which is an additional element in a ponzi scheme. The trick in a ponzi scheme is to never pay out anything. You just send the investors statements which make it look like they are making ridiculously high returns and hope that their naive nature and greed keeps them in the game.
If you read that description of a ponzi scheme and apply what you know about how MT and Pedro say the PDR Exchange is supposed to function, you will see it is nothing more than a scheme taken from a blueprint of a typical ponzi game.
MT is really a fairly slovenly and stupid creature.
