#BTCWhaleMovement Cryptocurrency (crypto) is a digital or virtual currency that uses cryptography for security. Unlike traditional money, it is decentralized and operates on blockchain technology—a public, distributed ledger that records all transactions. Bitcoin, launched in 2009, was the first cryptocurrency. Others include Ethereum, Binance Coin, and Solana. Crypto allows peer-to-peer transactions without needing banks or intermediaries. It offers fast, borderless payments and potential investment opportunities. However, it is also known for price volatility and security concerns. People use crypto for trading, investing, and sometimes daily purchases. As technology grows, cryptocurrency continues to reshape finance and digital ownership globally.
