Pump and Dump 

I have been getting alot of messages to join pump and dump groups. Also I have been checking it out. Last time I saw a group of like 7000 people. They inflated the price with 3000%.. it was astronomical. Some people must have made like tens of thousands of dollars in a matter of minutes.

But I am not ever going to participate in any of them, but it was interesting to witness. But my thoughts are.. how is this going to evolve and how can this be regulated? 

Manipulating and stealing..

I mean it is basically manipulating people in joining the pump but if your too late.. and a big whale drops the bomb. You are to late to sell, and essentially loose a big portion of your money. It is clearly just deceiving people and then robbing wealth from others. 

What do you guys think about these phenomena? 

And what can we do about it? :/
