Every market can be manipulated, there are so many whales in the community...
But still the manipulation will never last for a long time.
People or majority of the people in the world will dictate the market price and demand.
I do not think that it is possible to influence the crypto market. For example, the exchange rate seriously changes because of the news background. However, it returns to its previous state further. Today, crypto is the topic everyone is talking about. What I want to say, you can not manipulate something that is in demand. Either a product is demanded or not.
