Methodology

The calculation uses the current Top 100 CoinGecko market-cap results, removes Bitcoin and selected stablecoins, and counts how many remaining assets have a higher 30-day percentage change than Bitcoin. Constituents and market data can change at any time.

This live breadth reading compares 30-day percentage performance for a CoinGecko market-cap basket (excluding Bitcoin and selected stablecoins) with Bitcoin. It is a descriptive market measure, not a prediction, recommendation, or substitute for due diligence.
