Altcoin Season Index rises to 39, up 6 points from yesterday

CoinMarketCap's Altcoin Season Index has risen to 39, an increase of six points from yesterday. The index is calculated by comparing the price performance of the top 100 coins, excluding stablecoins and wrapped coins, against Bitcoin over the last 90 days. An altcoin season is declared when 75% of these coins outperform Bitcoin over that period, while the opposite is considered a Bitcoin season. A score closer to 100 indicates a stronger altcoin season.
