I assume the market's controlled and manipulated indirectly by crypto millionaires and billionaires. They arevconstantly pumping and dumping. That is the name of the game. Some of these people are also involved in the mining process which is a huge business in itself.
Rich people will have a big effect for everyone if they will sell their Bitcoin with a very large amount then the price will experience a drastic change.
Yes they have big contribution that may effect crypto market but it doesnt mean they can control the market, the value in the market fluctuates base on the demand and supply and not just because of rich people invest huge money to control crypto market.
