- Altcoin Season Index increased from Bitcoin Season levels, now at 39, showing a consistent trend away from Bitcoin’s recent dominance.
- Bitcoin dominance dropped sharply as the Altcoin Index gained strength, hinting at a broader altcoin market resurgence.
- The chart shows a steep rally in late 2024 and a recent strong rebound, possibly leading back into full Altcoin Season soon.
The Altcoin Season Index is showing early signs of transition, with values rising steadily and Bitcoin dominance falling over recent months.
Bitcoin Season Fades as Altcoin Index Recovers
The Altcoin Season Index, which ranges from 0-100, hit the lowest levels around mid-2024, indicating a period of Bitcoin dominance. At that point, the index was below 25 and strongly indicated the market was primarily driven by BTC. However, late 2024 saw a sharp increase in the index, which briefly broke into Altcoin Season territory after crossing the 75 threshold.
By early 2025, the index surged past 90, indicating intense altcoin activity before reversing course. Bitcoin regained its dominance shortly after, pushing the index back into the Bitcoin Season zone. Between February and May 2025, the index mostly fluctuated between 15 and 30, maintaining BTC’s control over the market.
That trend started to change in June 2025. A strong upward move took the index above the Bitcoin Season range. As of the last reading, the index is at 39, definitely recovering from the recent lows.
Market Dynamics Point Toward a Potential Altcoin Season
According to TheCryptoLark, Bitcoin dominance is steadily declining, while the altcoin index is gaining traction. The momentum appears to be building toward another Altcoin Season if the current trend continues. With the index rising, altcoins are starting to attract increasing investor attention, hinting at broadening market activity.
Further supporting this shift, @cas_abbe observed that Phase 2 has already started, with Ethereum beginning to outperform Bitcoin. He noted that if this trend holds for another one to two weeks, the market will likely enter Phase 3. In this stage, large-cap altcoins typically experience rapid growth.
He also outlined a possible Phase 4, where small-cap tokens often see sharp price increases, sometimes doubling or tripling within a single day. He anticipates this phase to occur sometime in Q4 2025.
Rising Momentum Favors Broader Altcoin Participation
Current indicators suggest that the market is gradually rotating out of Bitcoin and into altcoins. Ethereum’s relative strength versus Bitcoin has been instrumental in this shift. As ETH leads the way, other large-caps may follow in the coming weeks.
With the index no longer in the Bitcoin Season zone, market watchers are closely tracking the next movements. The recent rally could mark the beginning of renewed altcoin momentum, as altcoin participation gains traction across various capital tiers.
