What is Cryptocurrency?

Cryptocurrencies are digital or virtual currencies that use cryptography for security and operate on decentralized networks based on blockchain technology. They enable secure, transparent, and typically decentralized peer-to-peer transactions without the need for intermediaries like banks. Bitcoin was the first cryptocurrency, introduced in 2009, and since then, thousands of other cryptocurrencies have emerged, each with its unique features and purposes. These digital assets have gained attention as a store of value, medium of exchange, and investment opportunity, with their value often subject to market fluctuations.
