I do, there are some giant Bitcoin wallets in the top 100 and some of them have been active over the last year which proves the owner hasn't lost control of them. If people using pools collaborate by combining their mining power it's possible that whales collaborate by all agreeing to buy or sell at the same time in the same direction. The power of a few 50k bitcoin wallets could crash the market, and the money those whales have could pump it.
I see so Bitcoin price is just manipulated and the price moving are just according to them?? So I can't trust my future bitcoin then since unlike fiat currency, exchanges rate there are because of economic matters and not manipulators.
