If you've ever opened a crypto price table with hundreds of rows and felt your eyes glaze over, a heatmap solves that exact problem. Instead of scanning numbers top to bottom, you scan a grid of colored tiles and let your eyes do the pattern-matching your brain is already good at.
What tile size means
Each tile's size on CryptoHeat represents either 24-hour trading volume or market capitalization, depending on which mode you select. Bigger tiles are either more heavily traded right now, or represent a larger share of the overall market by value. A tiny tile isn't necessarily a bad coin — it might just be a smaller-cap asset with lighter trading activity today.
What color means
Color encodes 24-hour price change. Green means the price is up over that period; red means it's down. The intensity of the color scales with the size of the move — a pale green tile might be up 0.5%, while a deep, saturated green tile could be up 8% or more. The same logic applies on the red side for declines.
A three-second scan
The real value of a heatmap is speed. In under five seconds you can answer three questions: Is the overall market green or red today? Are the big, established coins (the large tiles) leading the move, or is it concentrated in smaller altcoins? And are there any standout tiles — unusually large or unusually saturated — worth a closer look?
What a heatmap doesn't tell you
A heatmap is a snapshot of price movement and size, not a signal to buy or sell. A coin can be deep green because of genuine adoption news, or because of a short-lived spike on thin volume that reverses within hours. Always check the actual price, volume, and market cap numbers on the coin's detail page before drawing conclusions — the heatmap is where you start looking, not where you stop.
