#TRXETF Cryptocurrency, or crypto, is a digital or virtual form of money that uses cryptography for security. Unlike traditional currencies issued by governments, crypto operates on decentralized networks based on blockchain technology—a distributed ledger enforced by a network of computers (nodes). The most well-known cryptocurrency is Bitcoin, but there are thousands more, including Ethereum, Litecoin, and Solana. People use crypto for various purposes such as online payments, investments, and decentralized finance (DeFi). Transactions are usually fast, borderless, and secure. However, due to volatility and regulatory uncertainties, crypto remains a high-risk asset. It’s reshaping finance, privacy, and digital ownership globally.
