Cryptocurrency

Cryptocurrency is a digital or virtual form of currency that uses cryptography for security. It operates on decentralized technology, typically a blockchain, which is a distributed ledger enforced by a network of computers (nodes). Cryptocurrencies are designed to work as a medium of exchange, allowing for secure and anonymous transactions between parties without the need for a central authority, such as a bank.

One of the key features of cryptocurrencies is their limited supply, which can help to maintain value. The most well-known cryptocurrency is Bitcoin, introduced in 2009, but there are thousands of other cryptocurrencies, including Ethereum, Ripple, and Litecoin, each with distinct features and uses.

Cryptocurrencies can be used for various purposes, including online purchases, investment, and as a means of transferring value across borders. They can be stored in digital wallets and traded on various cryptocurrency exchanges. The decentralized nature of cryptocurrencies can offer greater financial freedom and privacy, but they are also subject to market volatility and regulatory scrutiny.
