Altcoin season occurs when the majority of top-performing cryptocurrencies (over 90 days) are altcoins instead of Bitcoin. The Altcoin Season Index reflects this, with a higher score when altcoins outperform Bitcoin and a lower score when Bitcoin dominates. Stablecoins like Tether and DAI, as well as asset-backed tokens (e.g., WBTC, stETH, cLINK), are excluded. If 75% of the top 100 coins outperform Bitcoin in the last 90 days, it's Altcoin Season.

The Altcoin Season Index assists traders and investors in several ways: ● Recognizing changes in market sentiment towards altcoins. ● Timing market entries and exits according to altcoin performance. ● Adjusting portfolio diversification in line with evolving market trends.
