CoinMarketCap’s Altcoin Season Index climbed 11 points from the previous day to 33. The gauge compares Bitcoin’s price performance with that of the top 100 cryptocurrencies by market capitalization, excluding stablecoins and wrapped coins. CoinNess analysis says altcoin season begins when at least 75% of those 100 assets outperform Bitcoin over 90 days, while the reverse indicates Bitcoin season. Readings closer to 100 represent stronger altcoin-season conditions.
