Why does high trading volume matter for cryptocurrency?

High trading volume indicates how much cryptocurrency is being bought and sold, which matters for several reasons. First, it shows market liquidity—meaning you can buy or sell large amounts without dramatically moving the price. High volume also suggests active interest and legitimacy; coins with minimal trading volume may be difficult to exit quickly. Additionally, volume helps traders identify genuine price movements versus manipulation. When price changes occur on high volume, they're typically more meaningful and sustainable. Low volume moves can reverse suddenly. For investors, high volume in major cryptocurrencies like Bitcoin and Ethereum indicates healthier, more stable markets with less risk of being unable to sell when needed.
