of course, I have experienced the occurrence of such manipulations, I once traded on an exchanger and the price of the token I had was manipulated by the existence of fake trading volumes, fake trading history and others.
If you've seen the fake trade history, then you and your money most likely being manipulated by the exchange. Try to change it. But the overall market is manipulated, but who and as it does I can not understand. Perhaps this involved large holders, but I'm not sure.
