Altcoin Season Index falls 4 points to 18

CoinMarketCap's Altcoin Season Index has dropped four points from the previous day to a reading of 18. The index compares the price performance of the top 100 coins, excluding stablecoins and wrapped tokens, against Bitcoin over the last 90 days. An "altcoin season" is declared when 75% of these top coins outperform Bitcoin during that period, while the opposite scenario is considered a "Bitcoin season." A score closer to 100 indicates a stronger altcoin season.
