Crypto metric signals altseason as Bitcoin market-cap share stalls below 60%
Glassnode’s Altcoin Cycle Signal printed a new altseason signal after a month of Bitcoin and altcoin market-cap gains.
Glassnode's Altcoin Cycle Signal has signaled a new "altseason" after a month of gains in both Bitcoin and altcoin market capitalization. Bitcoin's recent rise to $86,000 has propelled altcoin markets higher, with the industry's market cap reclaiming $3 trillion. Glassnode's proprietary metric, the Altcoin Cycle Signal, has flipped to favor altcoin outperformance by comparing the market cap of the top 250 cryptocurrencies to Bitcoin.
The signal currently measures 81.25 on its normalized scale, indicating stronger altcoin growth compared to Bitcoin. The seven-day rolling mean value of the signal measured 81.25 on its normalized scale from 0-100 as of Monday. Bitcoin's dominance over the total crypto market cap has remained within a narrow range, sitting at 59.7% as of Monday, down slightly from 59.2% on August 19.
Trader Matthew Hyland described a state of "complacency" among Bitcoin investors, suggesting they remain unwilling to accept Bitcoin's lack of progress against altcoins since mid-June 2025. ETF inflows in Bitcoin and altcoin products have rebounded this week, with US spot Bitcoin ETFs seeing $999 million in combined inflows and Ether (ETH) ETFs taking in $270 million, both the highest since October 2025.
