Altcoin Season Index edges up to 19

CoinMarketCap's Altcoin Season Index has risen one point from yesterday to 19. The index is calculated by comparing the price performance of the top 100 coins by market capitalization, excluding stablecoins and wrapped coins, against Bitcoin. An "altcoin season" is declared when 75% of these top coins outperform Bitcoin over the past 90 days. A score closer to 100 indicates a stronger altcoin season, while the opposite is considered a "Bitcoin season."
