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.
There's an opinion the market is ruled by whales and mining pools. But one recent research has shown only 1/3 of whales having large amounts of cryptocurrencies actively participate in the market. So they rather TRY to rule, but sometimes the mass of people reverse the market!
