Cryptocurrency, often referred to as crypto, is a type of digital or virtual currency that uses cryptography for security. Unlike traditional currencies issued by governments (such as the US dollar or Euro), cryptocurrencies operate on decentralized networks based on blockchain technology. This technology enables secure and transparent transactions without the need for intermediaries like banks. Bitcoin was the first decentralized cryptocurrency, introduced in 2009, and since then, thousands of other cryptocurrencies have been created, each with its own unique features and purposes. Some popular cryptocurrencies include Ethereum, Ripple (XRP), Litecoin, and Cardano, among others. Cryptocurrencies can be used for various purposes, including online purchases, investment, and as a means of transferring value across borders quickly and securely.
