Cryptocurrency is a digital or virtual form of currency that uses cryptography for secure transactions, control the creation of new units, and verify the transfer of assets. It is decentralized and operates on a technology called blockchain, which is a distributed ledger that records all transactions across a network of computers. Unlike traditional currencies issued by governments, cryptocurrencies are not controlled or regulated by any central authority. This means that transactions can be made directly between parties without the need for intermediaries like banks. Cryptocurrencies are based on cryptographic principles that ensure secure and private transactions. Some popular examples of cryptocurrencies include Bitcoin, Ethereum, Lite coin, and Ripple. These digital assets can be used for various purposes, including online purchases, investments, money transfers, and even as a store of value..
