December 24, 2025, 12:31 AM
CoinMarketCap's Altcoin Season Index has risen two points from yesterday to 18. The index is calculated by comparing the price performance of the top 100 coins by market capitalization, excluding stablecoins and wrapped coins, against that of Bitcoin. An "altcoin season" is declared when 75% of these top 100 coins outperform Bitcoin over the preceding 90 days. Conversely, a low score indicates a "Bitcoin season," with a reading of 100 representing the peak of an altcoin season.Log in to leave comments!
