CoinMarketCap’s altcoin season index has fallen to 41, indicating a neutral market phase rather than a clear Bitcoin or altcoin season. The index compares Bitcoin’s 90-day price performance with that of the top 100 cryptocurrencies by market capitalization, excluding stablecoins and wrapped tokens. A reading of 75 or higher means at least 75% of those assets outperformed Bitcoin and signals altcoin season, while a reading below 25 indicates Bitcoin season. At 41, the market is showing mixed performance, with some altcoins outperforming Bitcoin but no broad-based altcoin rally. The measure can help investors assess market cycles and asset rotation, but it is not predictive and should be considered alongside other indicators and fundamental analysis.
