According to CoinMarketCap, the 'Altcoin Season Index' has surged to 47, reflecting a 9-point increase from the previous day. This index measures the performance of altcoins relative to Bitcoin, indicating that altcoins are currently outperforming the dominant cryptocurrency. The Altcoin Season Index is calculated by comparing the price涨跌幅 of the top 100 coins, excluding stablecoins and wrapped coins, against Bitcoin's涨跌幅 over the past 90 days. When 75% of these coins exhibit a higher涨跌幅 than Bitcoin, an altcoin season is considered to be in progress. Conversely, when the majority of coins underperform Bitcoin, it is considered a Bitcoin season. A higher Altcoin Season Index suggests a stronger altcoin season. As the index approaches 100, it indicates a dominant altcoin market. Currently, the index sits at 47, suggesting that altcoins are gaining traction but still have room to rally further.
