Experts predict a possible start of the altcoin season in September 2025, focusing on the rise of Ethereum, Solana, and other altcoins amid declining Bitcoin dominance.
Altcoin Season Signals and Declining Bitcoin Dominance
David Duong, Global Head of Research at Coinbase Institutional, stated that "September could mark the start of an altcoin season," citing three key market shifts: falling bitcoin dominance, improving liquidity, and renewed investor appetite to shift gains toward altcoins. This prediction is driven by observed declines in Bitcoin dominance and improving liquidity conditions.
Altcoins Overtake Ethereum and Bitcoin in Volume
Analysts observe that altcoin trading volumes are beginning to surpass both Ethereum and Bitcoin in monthly transactions. This reflects a growing interest in investment diversification amid current market conditions.
Capital Cycle Predictions in the Cryptocurrency Market
Historically observed capital cycles show that investments first flow into Bitcoin, followed by Ethereum and smaller altcoins. These patterns align with Coinbase’s forecasts of a forthcoming altcoin season, indicating that the outcome of the season depends on macroeconomic factors and institutional support.
There is a high likelihood that upcoming changes in cryptocurrency market dynamics, such as declining Bitcoin dominance and increasing interest in altcoins, may create conditions for the onset of an altcoin season in September 2025.
