Cryptocurrency is a digital or virtual currency that uses cryptography for security, operating independently of central banks and allowing direct transfers between individuals without intermediaries. Transactions are recorded on a decentralized public ledger called a blockchain, maintained by a global network of computers. Cryptocurrency is created through mining, which involves solving complex math problems using computer processing power. While offering benefits like decentralization and lower fees, cryptocurrency also entails risks such as volatility and lack of regulation. Popular cryptocurrencies include Bitcoin, Ethereum, Litecoin, and Ripple. The future of cryptocurrency will depend on continued evolution, adoption, and regulation.
