Seen indeed some manipulations going on, big whales driving prices up and down. But that does not mean exchanges should stop working. When believing in conspiracies, exchanges are working together with the whales; let the exchange crash, and the prices are back to square one, cheap for the whales to buy in again. But that said, I general do not believe in conspiracy theories. But I do know these exchanges are not engineered how they should have been engineered :(
