The trading volume of cryptocurrency refers to the total monetary value or quantity of digital assets bought, sold, or exchanged across global cryptocurrency exchanges over a specific timeframe, typically measured on a 24-hour basis. This metric serves as a crucial indicator of market liquidity, investor interest, and overall market activity. High trading volumes generally signify strong market participation and ease of executing trades, whereas low volumes can signal stagnation, heightened price volatility, and potential liquidity risks for traders.
