Altcoin Season Index Drops to 22, Bitcoin Dominance Continues

The Altcoin Season Index has dropped to 22, indicating a period of Bitcoin dominance in the cryptocurrency market. This index, which measures the relative strength of altcoins against Bitcoin, has retreated from the 75 level that signifies a full Altseason. The current low index value suggests that altcoins are not performing as well as Bitcoin, and there is no immediate sign of a reversal in this trend.

The last significant altcoin rally occurred in late 2024 when the index briefly surpassed the 75 level. Since then, the trend has reversed, leading to a period of low volatility for altcoins. Despite some resilience in the broader market, most altcoins have not recovered to their previous highs and have continued to underperform Bitcoin in the first half of 2025.

Historical data shows that the Altcoin Season Index peaked in late 2024 and then steadily declined. The index reached a high above 75 in the fourth quarter of 2024, indicating a period of strong altcoin performance. However, this was followed by a loss of momentum that continued into 2025. The current reading of 22 reflects a shift in capital away from altcoins and back into Bitcoin.

Since March 2025, the index has struggled to reclaim the neutral zone above 25. Multiple attempts to break this level in April and May were unsuccessful, indicating that traders have not significantly rotated into altcoins. While Bitcoin remains strong, historical patterns suggest that altcoin seasons tend to follow periods of sustained underperformance.

Despite the current low index value, market observers are still hopeful for a potential shift in the market. Altcoin markets have previously produced daily gains of 40% during active seasons, and these sharp rallies often emerge after prolonged periods of Bitcoin dominance. Although no clear catalyst has emerged to trigger this shift, the current setup resembles past cycles where altcoin strength re-emerged after periods of low index readings.

Traders are cautious but have not abandoned the altcoin narrative. Until the index crosses back above 25 with strength, altcoins may continue to lag behind the broader crypto market. The market is awaiting a momentum shift that could signal the return of high-volatility gains for altcoins.
