People who use it
Cryptocurrencies are decentralized and not controlled by any government or financial institution. Instead, cryptocurrencies are controlled by the people who use them. There is no central authority that controls cryptocurrencies. Cryptocurrency is completely decentralized, so no government or central bank can control it. Cryptocurrency creators, whales (individuals or groups of individuals who can influence the Bitcoin market), private investors, governments, etc. are some of the entities that control cryptocurrencies.
