Trading volume, explained simply
Volume tells you how busy a coin is: how much of it changed hands. It helps you judge whether a price move is serious.

Basahin sa FilipinoWhat is volume?
Volume is how much of a coin was bought and sold in a period, usually one day, counted in dollars or in coins.
1,000 people each buy $100 of a coin today → that day’s volume is $100,000
Why does a move with high volume matter more?
A price move backed by lots of trading shows many people agree. The same move on very little trading can be just a few people, and it can reverse quickly.
| Coin | Price today | Volume today | What it suggests |
|---|---|---|---|
| Coin A | +15% | $50 million (5× its usual) | Lots of buyers: a strong, real move |
| Coin B | +15% | $20,000 (its usual) | A few trades pushed it: easy to fall back |
Why are coins with very low volume risky?
- Prices jump easily: one $1,000 order can move the price a lot.
- Hard to sell: if few people are buying, you may have to sell for less than the price you see.
- Easy to manipulate: scammers prefer quiet coins for pump-and-dumps.
How is volume different from market cap?
| Market cap | Volume | |
|---|---|---|
| Measures | The size of a coin: the value of all its coins together | How busy it is: how much traded today |
| Changes | Slowly, with the price | A lot from day to day |
| Example | $1 billion | $40 million traded today |
A big coin with tiny volume is quiet; a small coin with huge volume is getting lots of attention.
