CoinMarketCap's Altcoin Season Index has fallen one point from the previous day to 17. The index measures whether altcoins are outperforming Bitcoin. It is considered an "altcoin season" if 75% of the top 100 cryptocurrencies, excluding stablecoins and wrapped tokens, have performed better than Bitcoin over the last 90 days. A score closer to 100 indicates a stronger altcoin season.Log in to leave comments!
