Crypto Heatmap — Real-Time Market Visualization

A crypto heatmap is a visual representation of the cryptocurrency market where each coin is shown as a rectangle. The rectangle's size represents the coin's market capitalization (larger = higher market cap), and its color represents the price change (green = price up, red = price down). It provides an instant overview of market sentiment and which sectors are gaining or losing.

This heatmap updates automatically every 30 seconds for price and change data, and every 5 minutes for market capitalization data. You don't need to refresh the page — the colors and values update in real-time.

Deep green indicates a strong price increase (8%+ in the selected period). Light green shows a moderate increase. Gray means the price is roughly unchanged. Light red indicates a moderate decrease, and deep red shows a significant drop. Use the 1h / 24h / 7d toggle to change which time period the colors represent.

Tile size is proportional to market capitalization (or 24h volume when toggled). Bitcoin has the largest market cap in crypto (typically over $1 trillion), so it always occupies the most space. Switch to Volume mode to see tiles sized by trading activity instead.

Use the scroll wheel (or pinch on mobile) to zoom in and out — zoom targets your cursor position. When zoomed in, click and drag to pan around the map. The +/- buttons control zoom, and the 1:1 button resets to the default view. Press and hold any tile for 3 seconds to open that coin's price page — a progress ring shows the countdown, release to cancel. Use the search box to find and zoom to a specific coin. On mobile, tap a tile to see its details.
