Lol, maybe after building those legitimate businesses, those that are behind the ponzi scheme might decide that it is time they stop this ponzi thing and focus on the real business… so what do you think is going to happen when they decide to make this kind of decision? A ponzi is still what it is, though there is the possibility that it can run for a long time, but if these business decides that they are no longer going to be part of it, then that means that it is over… unless that community continues to grow. Take for example – Bitcoin. The thing that is holding Bitcoin is the strong community… and since it keeps on growing, it will be difficult for Bitcoin to stop.
