CoinMarketCap's Altcoin Season Index stands at 18

CoinMarketCap's Altcoin Season Index is currently at 18. The index is calculated by comparing the price performance of the top 100 cryptocurrencies by market capitalization, excluding stablecoins and wrapped coins, against Bitcoin. An "altcoin season" is indicated when 75% of these top coins have outperformed Bitcoin over the past 90 days. A score closer to 100 suggests an altcoin season, while the current low figure points to a "Bitcoin season."
