Understanding the Altcoin Season Index
The Altcoin Season Index assesses the performance of altcoins relative to Bitcoin. A common metric involves tracking if at least 75% of the top altcoins outperform Bitcoin over the last 90 days.
Key Indicators
- Bitcoin Dominance: A decline in Bitcoin’s market share often signals altcoins are gaining momentum.
- Altcoin Market Volume: Significant increases in altcoin trading volume and prices, while Bitcoin remains stable, can indicate an altcoin season.
- Top 50/100 Performance: If 75 out of the top 50 or 100 coins outperform Bitcoin over 90 days, it suggests an altcoin season. Conversely, if only 25 or fewer outperform, it’s considered Bitcoin season.
- Social Sentiment: Shifts in social media and community sentiment towards altcoins can also be an indicator.
Current Market Analysis
Early 2025 saw relatively high Bitcoin dominance, suggesting an absence of altcoin season then. As of July 21, 2025, the Blockchaincenter’s Altcoin Season Index stood at 59, based on the top 50 coins.
Using the Index
The Altcoin Season Index helps identify profitable trading opportunities, time Bitcoin-to-altcoin rotations, and manage risk.
