Nothing we can do. Not possible. The only thing is to hold your cryptos and dont fall for their game.

Technically, market manipulation is proportionally difficult to the transactions volumes. Higher the volumes, more difficult to manipulate. If we assume there are some players manipulating the market, they can only gain when other players (plebs) follows their moves: buy with them, sell with them. So one way to shut them down is to trade against them. Buy when market dips (before they start buying) and sell on market peaks (before they start selling).
