Central bank policymakers oversee the money supply as part of monetary policy. Money is made up of assets that are used to purchase goods and services as well as acting as a store of value, a unit of account, and a medium of exchange. Cryptocurrencies are virtual money that exchange values through the use of cryptography. Their system is based on blockchain technology, which keeps a public, decentralized ledger of all transactions.

The main reason it matters is that Bitcoin eliminates the need for an intermediary and enables any two people, anywhere in the world with an internet connection, to transfer money in a matter of minutes (Vigna, 2021). Anything can be digitalized and swiftly and affordably swapped with this kind of technology. For monetary authorities, cryptocurrencies may present new difficulties like enhanced financial stability. There are benefits and hazards associated with managing the money supply in various ways. thoughts
