Question 1

How It Works

Accepted Answer

The heatmap displays each cryptocurrency as a rectangle: - **Size** proportional to market capitalization (bigger market cap = bigger rectangle) - **Color** based on 24-hour price change: - **Green shades** → Positive price change (brighter = larger gain) - **Red shades** → Negative price change (brighter = larger loss) - **Gray** → Near zero change
