The Altcoin Season Index, a metric used to measure the relative performance of altcoins compared to Bitcoin, has remained at 65 as of 9:30 AM KST. This indicates that the market sentiment remains neutral, with neither altcoins nor Bitcoin showing a clear dominance. The index is calculated by comparing the price fluctuations between the top 100 coins (excluding stablecoins and wrapped coins) by market capitalization and Bitcoin. When 75% or more of the top 100 coins have a higher rate of increase than Bitcoin over the past 90 days, it is considered altcoin season. Conversely, a Bitcoin season is indicated when less than 25% of the top 100 coins have a higher rate of increase than Bitcoin. The Altcoin Season Index can provide insights into the overall trend of the cryptocurrency market and help investors make informed decisions about their portfolios. While it is not a definitive indicator, it can be a useful tool for gauging investor sentiment and identifying potential investment opportunities.
