Pump and dump groups are using YOU as the pumper.

They release information, you'll buy in some of that coin because you have a subscription, and then the coin price goes up, everyone thinks that it is because of the pump group that the coin has gone up, but it was actually the subscribers themselves who drove the price up.

And what do they get out of this? They charge you for your subscription, and also they get profits too for nothing when they invest early before everyone else knows what they are going to pump.
