Altcoin Season Index Hits 54, Approaching Threshold for Market Shift

The Altcoin Season Index has risen to 54 on a rolling 90-day comparison of Bitcoin versus top 100 cryptocurrencies, bringing it closer to the 75 threshold that historically signals an altcoin season. This increase is driven by higher mid-cap trading volume and renewed interest in DeFi and layer-2 projects, which have benefited from regulatory clarity and network upgrades.

The index compares the 90-day price performance of Bitcoin against the top 100 cryptocurrencies by market capitalization, excluding stablecoins and wrapped tokens. A reading of 54 indicates that altcoins are gaining relative strength but have not yet decisively outperformed Bitcoin across the board.

Historically, periods where the index rises steadily above 50 have preceded broader market rotations, where capital flows from Bitcoin into smaller-cap cryptocurrencies. However, the index remains below the definitive altcoin season mark, suggesting that Bitcoin still holds relative strength compared to the broader market.
