Cryptocurrency is a digital or virtual currency that uses cryptography for security and operates independently of a central bank. Cryptocurrencies use decentralized technology to enable secure and anonymous transactions and to manage and verify the transfer of funds. Bitcoin, which was created in 2009, is the first and most well-known cryptocurrency, but there are now thousands of different cryptocurrencies in existence. Each cryptocurrency typically has its own blockchain, which is a decentralized ledger that records all transactions that have ever occurred on the network. In recent years, cryptocurrencies have gained mainstream acceptance and are increasingly being used as a means of payment and investment. However, they are still subject to volatility and regulatory uncertainty.
