Reading a Market Cap Heatmap
A crypto market cap heatmap visualizes the entire market in a single view using two dimensions:
- Color indicates price performance — green for gains, red for losses
- Block size represents market capitalization — larger blocks for BTC and ETH
What Heatmaps Reveal
- Sector rotation — When DeFi tokens turn green while Layer-1 chains stay red, capital is rotating
- Market breadth — Is the rally broad-based or narrow (only BTC/ETH moving)?
- Altcoin season signals — When small blocks outperform large ones, capital flows into higher-risk assets
- Risk-off sentiment — Uniform red indicates market-wide selling
Trading Applications
- Pre-trade context — Instant macro picture before entering any position
- Sector analysis — Identify leading or lagging categories (DeFi, L1, L2, Gaming, AI)
- Portfolio monitoring — Quickly assess holdings relative to the broader market
The StratBase.ai heatmap is powered by CoinGecko data, covering hundreds of cryptocurrencies with updates every 6 minutes.
