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.
As what is stated crypto currency is decentralized thus theres no particular group or individual who runs the system but the users are the navigators who implemented several rules and regulations in order to have their cryptos unique and secured.
