Altcoin Season Index holds steady at 19

CoinMarketCap's Altcoin Season Index stands at 19, unchanged from yesterday. The index is calculated by comparing the price performance of the top 100 cryptocurrencies by market capitalization, excluding stablecoins and wrapped coins, against Bitcoin over the past 90 days. An "altcoin season" is declared when 75% of these top coins outperform Bitcoin during that period, with a score closer to 100 indicating stronger altcoin performance.
