Cryptocurrency is a type of digital asset that operates without a central bank or government, using technology to record and verify transactions. The best-known example is Bitcoin, though many others exist. Cryptocurrency markets are known for being highly volatile — prices can move dramatically in short periods — and they trade around the clock. Prices are influenced by factors such as regulation, technology developments, and shifts in investor sentiment. Because of the sharp price swings, cryptocurrency carries notable risk, and understanding that volatility is essential for anyone following these markets.
