Cryptocurrency is digital or virtual money that exists only online and is not controlled by any government or bank. Instead, it uses blockchain technology, which is like a secure digital ledger that records all transactions. Cryptocurrencies, such as Bitcoin, Ethereum, and others, are created through mining, or they can be bought and traded like stocks. They are decentralized, meaning no single person or organization controls them, making them different from traditional currencies like dollars or euros. People use cryptocurrencies for online payments, investments, or as a way to store value.
