Bitcoin, created in 2009, is the first and most popular cryptocurrency, used for secure, peer-to-peer digital transactions without the need for banks. It runs on blockchain technology, a decentralized public ledger that records every transaction. With a limited supply of 21 million coins, Bitcoin is often considered digital gold and is widely used for payments, investment, and international remittances. Other cryptocurrencies like Ethereum, Litecoin, and Ripple serve different purposes. Ethereum enables smart contracts and powers decentralized finance (DeFi) and NFTs. Litecoin offers faster transactions, while Ripple is used for low-cost, cross-border payments. Privacy coins like Monero provide anonymous transactions. Many businesses now accept crypto as payment, and users store their coins in digital wallets. As the crypto space grows, it is reshaping finance, investing, and digital ownership worldwide.
