What is crypto currancy

Cryptocurrency is a digital or virtual form of currency that uses cryptography for security and operates independently of a central bank. It's decentralized, meaning it's not controlled by any single authority, like a government. Transactions are recorded on a distributed ledger called a blockchain, which ensures transparency and immutability. Bitcoin, Ethereum, and Litecoin are among the most well-known cryptocurrencies, each with its own unique features and purposes. Crypto has gained popularity for its potential to revolutionize finance, offering faster, cheaper, and more secure transactions compared to traditional banking systems. However, it's also subject to volatility and regulatory challenges.
