Remember, this whole thing about crypto is largely decentralized, thus, there is no single authoritative body in control of the crypto market. Although there are few centralized platforms among crypto, the market is largely influenced by the efforts and influence of the users of crypto. How well sellers and buyers treat the coins on the market affect the performance of the market.
Big players as well as small players, basically are called users this is the same as us. When they or we, sell or buy transactions, they or we have contributed to the rise and fall of prices. So, everything's very clear the user is the only one, who controls the market.
