CoinMarketCap’s Altcoin Season Index fell 13 points from the previous day to 38, following an earlier reported reading of 51. The gauge compares Bitcoin’s 90-day price performance with that of the top 100 cryptocurrencies by market capitalization, excluding stablecoins and wrapped coins or tokens. An altcoin season requires at least 75% of eligible cryptocurrencies to outperform Bitcoin, while the opposite condition is classified as Bitcoin season; readings closer to 100 indicate stronger altcoin-season conditions.
