According to the latest data from CoinMarketCap, the Altcoin Season Index remains at 36, unchanged from the previous day. This figure sends a clear market signal: current funds are still highly concentrated in Bitcoin, rather than flowing broadly into other crypto assets. As a key indicator for measuring crypto market sentiment, the index determines how many of the top 100 cryptocurrencies (excluding stablecoins and wrapped assets) have outperformed Bitcoin over the past 90 days. When more than 75% of altcoins outperform BTC, the market enters "altcoin season"; conversely, it is a "Bitcoin dominance period." The current reading of 36 indicates that only a few mainstream altcoins have outperformed Bitcoin, consistent with the typical characteristics of a strong Bitcoin cycle.
Historical data shows that such low index values often appear during market corrections or periods of increased macroeconomic uncertainty. The bull market peaks of 2017 and 2021 witnessed the index breaking through 75, when assets such as Ethereum, XRP, and Litecoin surged due to the DeFi News and NFT craze, and investor risk appetite was high. In contrast, Bitcoin has once again become a safe haven for funds due to its liquidity advantages, brand recognition, and institutional allocation demand. The persistently low index reflects that the market has not yet formed a systematic rotation expectation for altcoins, and investors prefer a more conservative approach.
It is worth noting that the index does not simply reflect price increases or decreases, but focuses on the competitive relationship of relative performance. Compared to macro indicators such as Bitcoin's market capitalization占比, it is better at revealing structural changes in the internal capital flow of the market. In the absence of a clear narrative driver or technological breakthrough, the altcoin sector is unlikely to have a systematic rebound momentum in the short term. Market participants need to pay attention to whether catalysts will emerge in the future, such as Ethereum upgrades, the rise of new public chain ecosystems, or shifts in macro liquidity, which may push the index back above the 50 threshold.
