Cryptocurrency is a digital or virtual form of currency that uses cryptography for security. Unlike traditional currencies issued by governments, cryptocurrencies are decentralized and typically operate on technology called blockchain. Bitcoin, the first and most well-known cryptocurrency, was introduced in 2009 by an anonymous entity known as Satoshi Nakamoto. Today, thousands of cryptocurrencies exist, each with unique features and use cases. As the world moves towards digital transactions, understanding cryptocurrencies can offer insights into the future of finance and investment. 💰📈🌐
