I've noticed that many newcomers to crypto don't fully understand why it's important to look at trading volume. Yet, it's one of the key indicators that helps you understand the actual market activity.

Cryptocurrency trading volume is simply the amount of an asset that has been bought and sold over a specific period (hour, day, week). It sounds simple, but this metric tells you a lot. When the volume is high, it usually indicates genuine interest in the asset. Price movements aren't random — people are actively buying and selling.

Why is this important? Imagine a situation: the price is rising, but the volume is falling. That's a red flag. It suggests the trend might weaken or reverse soon. Conversely, if the price is going up along with increasing volume, that's a more reliable sign of sustained demand.

Another point is liquidity. The higher the trading volume, the easier it is to enter or exit a position without significantly impacting the price. This is critical for active traders and large investors. If an asset is illiquid, a big order can sharply move the price.

A sudden spike in volume often signals the start of a new trend or a reversal. Traders watch for these moments to enter profitable positions or exit before the trend collapses.

In practice, each exchange displays trading volumes for each trading pair. For example, you can look at the volume for BTC/USDT, SOL/USDT, and so on. Currently, the market leaders by volume are Bitcoin, Ethereum, and stablecoins like USDT (over the past 24 hours around 63.98 billion), USDC, and FDUSD. But the altcoin rankings are constantly changing — Dogecoin, Pepe, and Shiba Inu are firmly in the top 20.

Exchanges show volume in several ways. You can see volume in a specific cryptocurrency or in fiat. There are aggregators that collect data across all platforms for a single coin, providing a complete picture of activity. For individual pairs, you can see where trading is concentrated.

If you're serious about trading, analyzing cryptocurrency trading volume is not optional — it's essential. It helps confirm the trend direction, find entry and exit points, and generally understand what’s really happening in the market. Don't rely solely on price — always check the volumes.
