Altseason Index: The "Quantifier" of Market Sentiment
The Altseason Index is a comprehensive indicator specifically used to measure the performance of altcoins relative to Bitcoin. Currently, there are two mainstream versions in the market—Blockchaincenter (top 50 cryptocurrencies) and CoinMarketCap (top 100 cryptocurrencies, excluding stablecoins). Although their methodologies differ, both agree that when 75% of non-Bitcoin cryptocurrencies have increased by more than Bitcoin over a 90-day period, we enter 'Altseason'.
From the current data, the Blockchaincenter index is 73, and the CoinMarketCap index is 69, both approaching the critical threshold of 75, indicating that the market has not fully entered the traditional sense of Altseason yet, but its obvious upward trend shows a clear start signal.
