Cryptocurrency is a type of digital money that exists only online. Instead of being controlled by a bank or government, it runs on special technology called blockchain, which keeps records of all transactions safe, transparent, and secure. This means people can send and receive crypto directly, anytime, anywhere, without needing a middleman.
The first and most famous cryptocurrency is Bitcoin, but there are now thousands of others, like Ethereum and Solana. Some are used to buy goods and services, others are for faster payments, and many are used as investments. In short, cryptocurrency is a new kind of money for the digital age—fast, global, and built on technology.
