- •Altseason Index reaches a high of 71, nearing critical levels.
- •A score above 75 typically marks full altseason territory.
- •Altcoins could soon outperform Bitcoin significantly.
The Altseason Index is a tool used by crypto analysts to gauge whether altcoins are outperforming Bitcoin. When this index rises above 75, it suggests a full altseason—a period where altcoins experience explosive price growth compared to Bitcoin. Right now, the index stands at 71, a strong sign that the market may be on the verge of entering this high-growth phase.
Why 71 is a Big Deal
An index level of 71 means altcoins are already gaining serious momentum. Traders and investors often watch for a reading above 75, which historically signals the start of a full-blown altseason. The closer the index gets to that threshold, the more money tends to flow from Bitcoin into mid- and small-cap altcoins. This shift can trigger massive rallies in projects that have been relatively quiet during Bitcoin’s dominant cycles.
The current reading of 71 shows that we’re not quite there yet—but we’re very close.

What to Expect in a Full Altseason
If the Altseason Index climbs just a bit higher, altcoins could enter a period of rapid gains. During previous altseasons, coins outside the top 10 saw returns ranging from 300% to over 1000% in just weeks. Investors typically rotate profits from Bitcoin into altcoins during this time, driving up demand and prices across the board.
Popular narratives such as Layer 2 scaling, AI tokens, DeFi, and memecoins could lead the charge in the next rally. However, volatility will also spike, so risk management becomes crucial.
