The Altcoin Season Index indicates that investors are still favoring Bitcoin over altcoins. During the entirety of 2025, the index has largely remained below half. As we went into 2025, that index of altcoins’ performance compared to Bitcoin really turned south. Since then it has floundered, barely able to gain any momentum.
The Altcoin Season Index has remained under the 75 threshold since late 2024. Retrospectively it has indeed failed to re-test this threshold. In late 2024, the index briefly showed promise, fluctuating towards the 75 level, suggesting a potential shift towards altcoin dominance. This proved to be short-lived.
Between January and mid-June 2025, the ASI remained far below the 25-threshold. Although it rose above this threshold briefly at the beginning of May, it soon retreated back down. This was a strong signal of the momentum early on, allowing for the Bitcoin-lead momentum to continue its run in crypto.
In short, the Altcoin Season Index is at about 22 right now. This puts the market firmly into what experts refer to as a “Bitcoin Season,” characterized by levels of 25 and under. The last time the index went into “Altcoin Season” territory, over 75, was in November of 2024.
Since the beginning of 2025, the Altcoin Season Index has been unable to cross above the 40 level. This trend further underscores Bitcoin’s undeniable market strength and staying power. As of June 15th, 2025 the Altcoin Season Index was still locked under 25, indicating a prolonged period of Bitcoin dominance.
"Bitcoin Season"
The Altcoin Season Index continues to languish, hovering at 22 for most of 2025. This trend indicates that investors continue to default to Bitcoin favored as a safe trade. This is indicative of how risk-averse we’re all feeling right now. They have more belief in Bitcoin’s long-term value than they do in the higher-risk, higher-reward potential available through altcoins.
