Cryptocurrency and Bitcoin.

Bitcoin is a decentralized digital currency, often referred to as cryptocurrency. It operates on a technology called blockchain, which is a distributed ledger enforced by a network of computers, ensuring transparency and security. Bitcoin can be used for various online transactions and is mined through a process where powerful computers solve complex mathematical problems to validate and record transactions on the blockchain.

Cryptocurrency is a type of digital or virtual currency that uses cryptography for security. Unlike traditional currencies issued by governments (fiat currencies), cryptocurrencies operate on decentralized networks based on blockchain technology. Blockchain is a distributed ledger that records all transactions across a network of computers. Bitcoin was the first cryptocurrency, and since then, numerous other cryptocurrencies, such as Ethereum, Ripple, and Litecoin, have been created, each with its unique features and purposes. Cryptocurrencies can be used for various applications, including online transactions, smart contracts, and decentralized finance (DeFi).
