Altcoin Cycle Signal indicates altseason as Bitcoin dominance stalls below 60%

Glassnode’s proprietary Altcoin Cycle Signal has crossed the threshold into “altseason” territory, reaching a value of 81.25 on its 0‑100 scale. The metric compares the market‑cap growth of the 250 largest altcoins (excluding stablecoins) to Bitcoin’s growth, and a reading above the midpoint suggests altcoins are outpacing Bitcoin.

Altcoin market cap expands

The combined market cap of the top 250 altcoins hit $1.19 trillion, the highest level since late January. Since August 19, altcoin market capitalization has risen by roughly 33 %.

Bitcoin dominance remains under 60 %

Bitcoin’s share of total crypto market cap has stayed in a narrow band around 59.7 %, failing to break the 60 % mark. This rangebound behavior contrasts with the earlier peak of 66 % in June 2025.

ETF inflows show renewed interest

Both Bitcoin and Ether exchange‑traded funds recorded their strongest daily inflows since October 2025. U.S. spot Bitcoin ETFs attracted about $999 million, while Ether ETFs saw $270 million in net inflows on the same day.

Market outlook

Analysts note a sense of “complacency” among Bitcoin investors, suggesting that the current dominance level may limit further upside for Bitcoin relative to altcoins.
