The Altcoin Season Index from crypto data platform CoinMarketCap has risen two points from yesterday to 48. The index is calculated by comparing the price performance of the top 100 coins by market capitalization, excluding stablecoins and wrapped tokens, against that of Bitcoin. An altcoin season is declared when 75% of these top coins outperform Bitcoin over the preceding 90 days; otherwise, it is considered a Bitcoin season. A reading closer to 100 indicates an altcoin season.Log in to leave comments!
