Cryptocurrency is a digital or virtual currency that operates on distributed ledger technology called a blockchain and uses cryptography for security. It is decentralized and operates independently of a central bank.
Unlike traditional currencies, cryptocurrencies are not backed by a physical commodity or government, and their value is determined by market demand and supply. Cryptocurrencies can be used to buy goods and services, transfer funds, and trade in markets. Popular cryptocurrencies include Bitcoin, Ethereum, Litecoin, Ripple, and Cronos.
