Cryptocurrency

Cryptocurrency is a type of digital or virtual currency that employs cryptography for security. Unlike traditional currencies issued by governments (fiat currencies), cryptocurrencies operate on decentralized networks based on blockchain technology, which is a distributed ledger enforced by a network of computers (nodes). This decentralization makes cryptocurrencies resistant to central authority manipulation or interference.

Cryptocurrencies enable peer-to-peer financial transactions over the internet, allowing users to send and receive funds without the need for intermediaries like banks. Each transaction is recorded on a blockchain, which ensures transparency and accountability. Cryptocurrencies can serve various purposes, including serving as a medium of exchange, a store of value, or an investment asset.

Bitcoin, created in 2009, was the first and remains the most well-known cryptocurrency. Since then, thousands of alternative cryptocurrencies (often referred to as altcoins) have emerged, each with unique features or intended use cases. The value of cryptocurrencies can be highly volatile, influenced by market demand, investor sentiment, regulatory developments, and technological advancements.
