In my opinion, pump & dump groups and the activity itself serves only the creator and close circle around him/her. So far, many people lost funds due to it and should be kept out of the industry.
yeah you are right, the Pump and Dump group must be kept away from the Cryptocurrency trading industry in the market and make the market stable and real, because many people lose funds due to price manipulation, but I think the Pump & Dump manipulation group is impossible to be eliminated, because the Cryptocurrency trading business is open, anyone can buy and sell crypto assets
