Cryptocurrency is a digital or virtual currency that uses cryptographic technology for secure transactions. Unlike traditional money issued by governments, crypto currencies operate on decentralized networks using blockchain technology. This means they are not controlled by any central authority, such as a bank or government.
Crypto currencies are stored in digital wallets and can be used for various transactions, including online purchases, investments, and peer-to-peer transfers. The most well-known cryptocurrency is Bitcoin, but thousands of others exist, each with unique features and uses.
