Altcoin Season Index rises to 51

CoinMarketCap's Altcoin Season Index has reached 51, up three points from the previous day. The index measures market sentiment by comparing the price performance of the top 100 coins, excluding stablecoins and wrapped tokens, against Bitcoin. An altcoin season is declared if 75% of these top coins have outperformed Bitcoin over the last 90 days; otherwise, it is considered a Bitcoin season. A score closer to 100 indicates a stronger altcoin season.
