Altcoin Season Index sits at 17

CoinMarketCap's Altcoin Season Index currently stands at 17. The index is calculated by comparing the price performance of the top 100 cryptocurrencies, excluding stablecoins and wrapped tokens, against Bitcoin over the past 90 days. An altcoin season is declared when 75% of these top coins outperform Bitcoin during that period. A score closer to 100 signifies an altcoin season, while the current low reading indicates a Bitcoin season.
