Altcoin Season Index holds steady at 21

CoinMarketCap's Altcoin Season Index is currently at 21, unchanged from the previous day. The index measures whether 75% of the top 100 cryptocurrencies by market capitalization, excluding stablecoins and wrapped tokens, have outperformed Bitcoin over the past 90 days. A score closer to 100 indicates an altcoin season, while a lower score points to a Bitcoin season.
