April 21, 2026, 12:26 AM
CoinMarketCap's Altcoin Season Index stands at 38, unchanged from yesterday. The index measures market sentiment by comparing the price performance of the top 100 cryptocurrencies, excluding stablecoins and wrapped tokens, against Bitcoin over the last 90 days. An "altcoin season" is declared when 75% of these top 100 coins outperform Bitcoin during this period. A score closer to 100 indicates a stronger altcoin season.Log in to leave comments!
