Altcoin Season Index rises to 51, up 3 points

CoinMarketCap's Altcoin Season Index has risen to 51, an increase of three points from yesterday. The index determines whether it is an "altcoin season" by comparing the performance of the top 100 coins (excluding stablecoins and wrapped coins) against Bitcoin. An altcoin season is declared when 75% of these top coins outperform Bitcoin over the preceding 90 days. Conversely, a period of Bitcoin outperformance is termed a "Bitcoin season." A score closer to 100 signifies a stronger altcoin season.
