Altcoin Season Index
23 of the 50 largest altcoins outperformed Bitcoin over the past 90 days.
How this is calculated
We take the 50 largest altcoins by market capitalisation — excluding Bitcoin itself, stablecoins and wrapped or staked derivatives such as WBTC, WETH and stETH — and compare each one's 90-day USD price change against Bitcoin's 90-day USD price change over the exact same rolling window. Coins with no reliable price 90 days ago are left out of the count rather than counted as underperformers.

FAQ
- What is the altcoin season index?
- A 0–100 score. It measures how many of the top 50 altcoins by market cap (stablecoins and wrapped BTC/ETH excluded) have outperformed Bitcoin over the past 90 days. 75+ = alt season. Under 25 = Bitcoin season.
- How is it calculated here?
- We take the top 50 non-stable, non-wrapped coins by market cap, compare their 90-day price change to Bitcoin's, count how many beat BTC, and scale that count to 0–100.
- Is a high number bullish for alts?
- It just means alts have outperformed BTC recently. It's a market-structure read, not a prediction — trends can turn.
