CoinMarketCap’s altcoin season index fell to 38, down 13 points from the previous day. The index compares Bitcoin’s 90-day price performance with that of the top 100 coins by market capitalization, excluding stablecoins and wrapped tokens. A reading of 75 or higher indicates an altcoin season, meaning at least 75% of those coins outperformed Bitcoin. The opposite conditions are classified as a Bitcoin season, while readings nearer 100 represent stronger altcoin-season conditions.
