The Altcoin Season Index has dropped to 22, signaling a dominant Bitcoin trend.
The 75 threshold marks a full Altseason, not seen since late 2024.
Despite current lows, historical patterns show sharp altcoin gains follow such downturns.
The altcoin market continues to live in the shadow of Bitcoin dominance, with the latest data from BlockchainCenter.net placing the Altcoin Season Index at a lowly 22. The index, which tracks relative altcoin strength against Bitcoin, is a clear retreat from the 75 level of outright Altseason. There is no immediate indication of reversal on the chart, highlighting prolonged weakness in non-Bitcoin assets.

The last big altcoin rally occurred in late 2024 when the index briefly burst above the 75 level. The trend has been reversing since then, pushing altcoin sentiment into a low-volatility range. Despite the broader market showing some resilience, most altcoins are far from recovering previous highs. Surprisingly, altcoins have continued to underperform Bitcoin in the first six months of 2025.
Previous Peak in Late 2024 Gave Way to Steady Decline
The graph shows that the Altcoin Season Index dropped drastically in Q3 2024 and rose to a high above 75 in Q4 2024. The area can be classified as a long-established Altseason area, which indicates a large-scale altcoin outperformance during that period. However, what followed was a steady loss in momentum that continued into 2025. The current reading of 22 reflects a broader rotation of capital away from altcoins and back into Bitcoin.
Since March 2025, the index has failed to reclaim the neutral zone above 25. Multiple short-lived attempts to break that level in April and May also failed. This pattern shows that traders have yet to rotate significantly into altcoins. While Bitcoin retains a strong position, historical patterns suggest altcoin seasons tend to follow periods of such sustained underperformance.
Market Watchers Still Expect a Return of High-Volatility Gains
Although the index remains suppressed, market observers continue monitoring for a potential shift. Altcoin markets have previously produced daily gains of 40% during active seasons. These sharp rallies tend to emerge when the Altcoin Season Index breaks out from prolonged Bitcoin-dominated phases.
At present, no clear catalyst has emerged to trigger that shift. However, the setup resembles past cycles where altcoin strength re-emerged after periods of low index readings. As it stands, traders appear cautious but are not abandoning the altcoin narrative. Until the index crosses back above 25 with strength, altcoins may continue lagging the broader crypto market.
