What's Cryptocurrency ?

Cryptocurrency is a digital or virtual currency that uses cryptography for security and operates independently of a central bank. Cryptocurrencies use a decentralized system, meaning they are not regulated or controlled by a government or financial institution. Instead, they rely on blockchain technology, a distributed ledger system that records all transactions and ensures the integrity and security of the currency. Cryptocurrencies such as Bitcoin, Ethereum, and Litecoin have gained popularity in recent years due to their potential for anonymity, low transaction fees, and ability to operate across borders.
