CoinMarketCap’s Altcoin Season Index stood at 23, down five points from yesterday, indicating a decline in altcoins’ relative performance against Bitcoin. While the current outlook is still far from an altcoin season, Bitcoin has continued to outperform most leading altcoins over the past 90 days. The index compares Bitcoin’s performance with that of the top 100 cryptocurrencies by market capitalization, excluding stablecoins and wrapped tokens. An altcoin season is identified when at least 75% of those assets outperform Bitcoin. A reading below 30 points to continued Bitcoin outperformance, while the current level shows that only a minority of altcoins have surpassed Bitcoin during the measurement period and altcoins haven’t established a broad dominance. The index is updated daily and serves as a lagging measure of recent market performance rather than a forecast.
