Cryptocurrency: A Brief Overview

Cryptocurrencies are digital or virtual currencies that use cryptography for security and operate independently of a central bank. They leverage blockchain technology, which is essentially a decentralized ledger that records all transactions across a network of computers. This makes cryptocurrencies highly secure and resistant to fraud.

Bitcoin, launched in 2009 by an unknown individual using the pseudonym Satoshi Nakamoto, was the first cryptocurrency and remains the most well-known today. Since Bitcoin's inception, thousands of other cryptocurrencies have emerged, each with its unique features and use cases. Ethereum, for instance, not only functions as a currency but also supports decentralized applications (dApps) through smart contracts.
