Altcoin Season Index stands at 19

CoinMarketCap's Altcoin Season Index currently stands at 19, indicating a Bitcoin season. The index measures whether 75% of the top 100 altcoins by market capitalization—excluding stablecoins and wrapped tokens—have outperformed Bitcoin over the past 90 days. A reading closer to 100 suggests an altcoin season, while a low score signifies that Bitcoin's performance is dominant.
