Cryptocurrency

Cryptocurrency is a digital or virtual form of currency that uses cryptography for security. It operates on decentralized networks based on blockchain technology, which is a distributed ledger that records all transactions across a network of computers. Unlike traditional currencies issued by governments (fiat currencies), cryptocurrencies are typically not controlled by a central authority, which makes them immune to government interference or manipulation.

Cryptocurrencies can be used for various purposes, including trading, investment, and as a medium of exchange for goods and services. Bitcoin, created in 2009, is the first and most well-known cryptocurrency, but there are thousands of alternatives, known as altcoins, with varying features and uses.

Transactions made with cryptocurrencies are generally pseudonymous, meaning that the identities of the users are not directly tied to their transactions. Various cryptocurrencies also provide different functionalities and levels of security, and they can be stored in digital wallets, which can be online or offline. The rise of cryptocurrencies has sparked discussions around regulation, security, and the future of finance.
