Cryptocurrency is different from traditional currency in a few ways. First, cryptocurrency is digital, meaning it doesn’t exist in physical form like paper money or coins. Second, cryptocurrency is decentralized, meaning it is not controlled by any one institution or government. Rather, it is created and controlled by its users, who use cryptography to ensure the security of their transactions. Finally, cryptocurrency operates on a blockchain, which is a digital ledger that maintains an immutable record of all transactions.
