What is cryptocurrency?
Cryptocurrency is a type of digital or virtual currency that uses cryptography for security. Unlike traditional currencies issued by governments and central banks, cryptocurrencies operate on decentralized networks based on blockchain technology. Here are some key points about cryptocurrency:
