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.
The ones in charge of cryptocurrency are the people who are in benefit in this technology. the more users, the more the crypto will be blooming and functional. otherwise it will wither and die. traders are usually one of the main manopulators of the market since they arenthe middleman of it. they sell and trade to keep the stocks flowing as long as people needed it.
