Manipulating the market requires super-large costs, and cannot be done alone. If there really is such an organization it should have been tracked for a long time, and I hope this is just a matter of concern.
It can be done, of course the bigger the exchange and the more expensive the asset, then the harder it is. But that's how whales do it, or even how exchanges collaborate together (I suspect this happens). If you read about these crypto owners who get jail time, they use all the customer funds to make big orders elsewhere.
