I don't think everyone can manipulate cryptocurrency. Ilon Musk and the war that the leaders of Russia have unleashed are good at it. Because a lot of external factors affect all of this. I think it is best to use anonymous exchanges to trade. Since your savings can only be under your control. I have read the information here and decided that it is best to use the DEX exchange. Unfortunately bitcoin is still standing still, I made a purchase recently and am waiting for it to rise.
