Wallstreet had trouble getting Bitcoin and the other currencies where they wanted it

Personally I don't agree. Many crypto traders are newbies who trade more than what they can afford to lose. In this scenario market manipulation is very easy, also considering that many exchanges charge 0 trading fees to operator who trade large volumes (for example whales). By this way, pump and dump also on short timeframes are very simple
If they manipulated crypto market, they did it very easily
