Cryptocurrency is a digital or virtual form of money that uses cryptography for secure transactions. Unlike traditional currencies, it operates on decentralized networks called blockchains, ensuring transparency and eliminating the need for intermediaries like banks. Popular cryptocurrencies include Bitcoin, Ethereum, and Dogecoin. Crypto can be used for payments, investments, and decentralized applications. Traders analyze price trends, market sentiment, and technical indicators to make informed decisions. While highly rewarding, it carries risks due to volatility. Learning, research, and risk management are essential. Cryptocurrency represents the future of finance, empowering users globally.
