Probably you are correct that whales are selling at 10k mark, but if you think about it, everybody is thinking the same. Everybody is waiting for the highest peak for now to sell then buy at the lowest price, it is the fastest way to earn a fortune in bitcoin. But to think that whales are manipulating it every time is a no for me. Whales are whales because they have money, they have other businesses to take care of too and they don't have the time to watch the market most of the time. We the people are manipulating the market no just the whales.
It is normal for everybody to think the same way, but have you not seen people thinking the same way before and then things not going as planned ?
Whales know what they are doing, they read emotions in the market, and they know when to distribute buying and selling and how to move the market. Traders are there trying to play their cards safely, but the main fact here is that the whales make the call and there is absolutely nothing we can all do about it. One reason they call them the market movers or makers.
