Altcoin Season Index
Is it time to hold Bitcoin or rotate into Alts? The Altcoin Season Index provides a definitive answer by comparing the 90-day performance of the top 50 cryptocurrencies against Bitcoin.
Problems it solves
Rotation Timing
Helps you decide when to take profits on Bitcoin and move into Altcoins, or when to head back to the safety of BTC.
Market Saturation Check
Identifies 'Extreme Altseason' (score > 75), which often signals that altcoins are overextended and due for a pullback.
Performance Benchmarking
Provides a clear view of which specific assets are outperforming Bitcoin over a medium-term horizon.
How to use correctly
1. Check the current index score. A score over 75 defines an 'Altcoin Season'.
2. A score below 25 defines a 'Bitcoin Season', where BTC is outperforming the majority of the market.
3. Use the index to avoid 'chasing' altcoins when the index is already at 90+.
4. Look for the 'Altcoin Season' threshold cross as a signal to start diversifying your portfolio.
Limitations
- ✕Excludes stablecoins and wrapped tokens, which can skew the 'Top 50' performance data.
- ✕A few massive outperformers (e.g., meme coins) can sometimes push the index higher than the 'average' altcoin.
- ✕It is a medium-term (90 day) indicator and may not capture short-term 'mini-altsessions'.
Best For
Portfolio managers and long-term traders who want to optimize their asset allocation between Bitcoin and the broader altcoin market.
