For me answer to this question that no one and nobody ever does control the crypto currency market. The price of the different crypto currency only changes because of the different factors that affect the crypto currency, such as the supply and demand. The people are the main element that control the market itself. and also this is true that the big whales or the billionaires who got majority of the coin controls the price of every coins. But people are responsible of controlling the price because the demand and supply of the cryptocurrency in the market decide what will be the price.
