Cryptocurrency is different from Fiat money in several ways. First, cryptocurrency operates independently of any centralized bank and government, whereas fiat money is issued and controlled by governments and backed by central banks. Second, cryptocurrency is a digital form of currency that exists only on the internet, whereas fiat money is a physical form of currency issued by paper notes and coins. Third, cryptocurrency transactions are secure and anonymous, whereas fiat currency transactions include personal information and are subject to regulation. Finally, cryptocurrency is decentralized, meaning it is not regulated by any single authorities, while fiat money is centralized and regulated by governments and financial institutions.
