The Altcoin Season Index has dipped to 17 on December 26, reflecting a slight decline from the previous day’s reading of 18, according to CoinMarketCap data tracked by Blockbeats. This metric gauges how many of the top 100 cryptocurrencies have managed to outperform Bitcoin over the preceding 90-day window—and right now, only around 17 projects have achieved that feat.

The current reading starkly contrasts with the index’s peak performance earlier this year. Back on September 20, the Altcoin Season Index reached 78, indicating a period when altcoin season appeared far more robust, with nearly four times as many projects in the top 100 beating Bitcoin’s returns. The dramatic drop from 78 to the current 17 underscores a significant shift in market dynamics over recent months.

Such persistently low readings suggest that Bitcoin continues to capture the majority of capital flows and investor attention within the crypto ecosystem. With only a small fraction of altcoins outperforming the leading digital asset, the altcoin season narrative remains subdued, and most traders are positioning themselves accordingly. This index serves as a barometer for whether money is flowing into alternative cryptocurrencies or consolidating around Bitcoin’s dominance.
