What does the crypto market heatmap show, and how do I read it?
The crypto market heatmap is a treemap — a space-packed visualisation that gives every tracked coin a rectangle whose size encodes its weight in the market (either 24-hour spot volume or aggregate perpetual open interest, toggleable above) and whose colour encodes its 24-hour price change. Deep green is > +5%, deep red is < −5%, and neutral grey means there's no clean 24h delta yet. One glance tells you whether the market is risk-on, risk-off, or in rotation.
The power of a treemap versus a flat ranked list is that you see proportionality at the same time as performance. If BTC is green while a wall of small-cap alt cells is red, capital is rotating from long-tail risk into the majors. If the whole canvas is green and roughly equal-sized, breadth is broad and trend-following systems are firing. If one alt cell dominates the canvas with a single-digit colour, you're looking at a focused flow event that's worth a click-through to the per-coin page.
Size basis matters: 24h volume captures who the market is paying attention to right now; open interest captures who the leveraged derivatives market is committed to. Switch between them to spot discrepancies — a coin that's large on volume but small on OI is a spot story; the inverse is a derivatives story. For the derivatives side, jump to the open interest dashboard, the funding rate heatmap, or live liquidations for the underlying flow.
