Crypto metric signals altseason as Bitcoin market-cap share stalls below 60%
Bitcoin’s surge to $86,000 lifted the broader crypto market above $3 trillion and triggered a stronger altcoin rally. Glassnode’s Altcoin Cycle Signal flipped toward altcoin outperformance, with its seven-day reading at 81.25, indicating “altseason” conditions as the market cap of the top 250 altcoins grew faster than Bitcoin’s. The combined altcoin market cap reached $1.19 trillion, its highest since late January, and is up 33% since Aug. 19. Bitcoin dominance has stayed rangebound near 59.7%, suggesting BTC has not regained clear control over market gains. ETF flows also rebounded sharply: US spot Bitcoin ETFs saw $999 million in daily inflows and Ether ETFs $270 million, both the highest since October 2025, showing broad renewed demand across crypto assets.
