#MarketRebound Cryptocurrency is a digital form of money that uses blockchain technology to secure transactions. Unlike traditional currencies, it isn’t controlled by a central bank. Bitcoin was the first and is still the most well-known cryptocurrency. Others include Ethereum, Solana, and Dogecoin. People can buy, sell, and trade crypto on various online exchanges. Some use it as an investment, while others use it for quick, global payments. Transactions are recorded on a public ledger called the blockchain, which makes them transparent and secure. As technology grows, crypto continues to gain popularity, though it can be risky due to market volatility.
