Lead
The Altcoin Season Index currently stands at 33, indicating it is not altcoin season. Over the past 90 days, 33 of the top 50 coins have outperformed Bitcoin—below the 75% threshold required to confirm altcoin season. It has been 138 days since the last altcoin season, with the historical average gap between seasons at 479 days.
Key Developments
- Altcoin Season Index: 33 (neutral-to-Bitcoin-leaning)
- Performance breadth: 33/50 top coins outperformed Bitcoin over the last 90 days
- Days since last altcoin season: 138
- Average days between seasons: 479
- The dashboard explicitly notes: > "It is not Altcoin Season!"
What the Index Measures
The Altcoin Season Index is an analytical indicator that tracks whether altcoins, on aggregate, are outperforming Bitcoin over a rolling 90-day period. By methodology, if 75% or more of the top 50 coins outperform Bitcoin, it is deemed Altcoin Season; if 25% or fewer outperform, it is Bitcoin Season. A reading of 33 sits between these extremes, suggesting the market has not yet rotated decisively into altcoins.

Market Context
- The current reading implies that Bitcoin dominance remains resilient, as a clear majority of top altcoins have not surpassed BTC's performance over the last quarter.
- Historically, decisive altcoin cycles tend to align with broad risk-on sentiment and liquidity rotation from Bitcoin into mid- and large-cap altcoins. The present data does not yet reflect that rotation.
Historical Perspective
- The index framework highlights past cycle extremes (e.g., earlier crypto bull markets) to contextualize rotations between Altcoin Season and Bitcoin Season.
- With 138 days since the last registered altcoin season and an average cycle gap of 479 days, the timing alone does not guarantee an imminent shift; breadth will be key.
Looking Ahead
Traders often watch this indicator for early signs of market rotation. A sustained rise toward the 75 level—paired with expanding altcoin breadth—would strengthen the case for a new altcoin cycle. Until then, the data continues to favor Bitcoin on a relative performance basis.
