Altseason Confirmed As Index Hits 76 While Bitcoin Season Slips to 25

The Altcoin Season Index reached 76 showing most altcoins have outperformed Bitcoin over 90 days.

Bitcoin season dropped near 25 as capital moved into altcoins creating stronger gains across the market.

Traders now ask if altcoins can hold dominance and extend gains while Bitcoin remains under pressure.

Altseason has officially arrived with the index reading 76, indicating altcoins are outperforming Bitcoin and capturing strong market momentum. The BlockchainCenter Altcoin Season Index now stands at 76, surpassing the critical threshold of 75 that defines altseason. This level shows that most altcoins have outperformed Bitcoin over the last 90 days.

By comparison, the Bitcoin Season threshold is set at 25, highlighting when Bitcoin dominance outweighs altcoin performance. The chart confirms that Bitcoin has underperformed while altcoins continue to rise across multiple categories.

The current index reading reflects a clear shift in trader preference. More capital is flowing into altcoins as their prices outperform Bitcoin. This move suggests growing investor appetite for higher volatility and speculative opportunities outside of the leading cryptocurrency.

The rise has been steady since mid-2025, following months of consolidation earlier in the year. September’s surge to 76 reinforces the notion that altseason is not only underway but also gaining traction.

Market Context and Trader Reactions

CryptoGoos, a market account, announced on September 11, 2025, that “Altseason is here now.” The statement accompanied the chart showing the index breaking above the 75 mark. The post has already drawn tens of thousands of views.

Traders on social platforms responded with excitement. Some labeled the moment as “inevitable,” while others described it as “time to print.” The reactions underscore the anticipation that altcoin-led markets often create.

Historical data shows that altseasons tend to emerge after long stretches of Bitcoin dominance. This pattern is now repeating as Bitcoin struggles to keep pace with the wider market. The chart depicts Bitcoin season values dropping closer to 25 as altcoins accelerate.

Increased trading activity in tokens beyond Bitcoin has also supported liquidity. Rising volumes in Ethereum, Solana, and other altcoins have contributed to the overall index surge. These movements further validate the transition into altseason territory.

Investor Outlook and Pivotal Question

The index reaching 76 has raised a key question: can altcoins sustain this dominance and continue outperforming Bitcoin in coming months? The answer will shape trading strategies across the sector.

Sustaining momentum above 75 requires continuous capital inflows and strong performance from major altcoins. If these conditions persist, the rally could expand further, with broader participation across mid-cap and smaller projects.

However, sharp reversals in altseason have occurred in the past. Any sudden recovery in Bitcoin’s dominance could shift momentum back. Traders remain cautious, but enthusiasm is evident as attention stays locked on altcoin gains.

The BlockchainCenter index remains the most cited measure for defining altseason. Its methodology, based on 90-day performance comparisons, provides a consistent benchmark for tracking shifts between Bitcoin and altcoins.

The broader market narrative now reflects a period where altcoins hold the spotlight. With the index firmly above 75, investor focus is shifting toward which projects will lead the rally. Altseason has begun, but its strength and duration remain to be tested.
