actually, between market manipulation and the occurrence of coin dumps both are just as frightening, it's just more frightening if there is a coin dump, because I personally experience it also investing in new coins and when listing on the exchange has experienced a sharp price drop. 70% of the initial price. This decline occurred because many bounty hunters/investors  sell directly when there is an opportunity and I am too greedy to wait 3x profit, but in the end I suffered a big loss.
