CoinMarketCap’s Altcoin Season Index rose four points from the previous day to 37, remaining below the 75-point threshold for altcoin season. The gauge compares the 90-day price performance of the top 100 cryptocurrencies by market capitalization with Bitcoin, excluding stablecoins and wrapped coins. Altcoin season is defined as a period when at least 75% of the tracked cryptocurrencies outperform Bitcoin, while the reverse is viewed as Bitcoin season. A reading closer to 100 indicates stronger altcoin-season conditions. The index measures historical relative performance rather than forecasting future market movements.
