CoinMarketCap Altcoin Season Index stands at 57

The index, published by the cryptocurrency market data platform, compares the price performance of the top 100 coins by market capitalization, excluding stablecoins and wrapped coins, against Bitcoin. An altcoin season is identified when 75% of the top 100 coins have outperformed Bitcoin over the past 90 days, while the opposite is considered a Bitcoin season. A reading closer to 100 indicates stronger altcoin-season conditions.
