Summary
Bitcoin’s price recently rose to $86,000, boosting the altcoin market and pushing the total crypto market capitalization above $3 trillion. Glassnode’s Altcoin Cycle Signal indicated a new “altseason” with a reading of 81.25 out of 100, reflecting stronger market-cap growth in the 250 largest altcoins relative to Bitcoin. Bitcoin’s dominance has stalled below 60%, remaining rangebound, while Bitcoin and Ether ETFs experienced their highest daily inflows since October 2025.
Why it matters
The source highlights that the Altcoin Cycle Signal's shift suggests altcoins may outperform Bitcoin in the current market cycle, potentially influencing investor allocation decisions. Additionally, the strong ETF inflows suggest renewed investor interest in both Bitcoin and Ether products. The impact of these developments on market sentiment or future price trends is not explicitly addressed by the source.
Key context
The Altcoin Cycle Signal from Glassnode compares the combined market capitalization growth of the 250 largest altcoins to Bitcoin, signaling “altseason” when altcoins outperform. Bitcoin dominance reached a high of 66% in June 2025 but has since stagnated around 59-60%. Recent crypto market gains coincided with a US Treasury announcement about bond market interventions, which may have helped spark altcoin rallies.
