Cryptocurrency is a digital form of money that uses blockchain technology to enable secure and decentralized transactions. Unlike traditional currencies controlled by governments or banks, crypto is powered by a peer-to-peer network, allowing users to send and receive funds globally with low fees and fast speed. Bitcoin, Ethereum, and Binance Coin are some of the most popular cryptocurrencies. Many investors see crypto as a store of value or a way to earn profits through trading. However, the market is highly volatile and can change quickly. As adoption grows, crypto is playing an increasing role in finance, technology, and global economies.
