Bitcoin's market dominance is projected to exceed 60% by September or October, according to analyst Benjamin Cowen. Despite a recent decline post-Jackson Hole summit, Cowen attributes this to a seasonal trend, with BTC dominance at 58.32% as of August 26, 2025. The altcoin season index has risen to 53, with Ethereum and Solana leading the charge, as Ethereum garners significant institutional interest. Cowen anticipates medium-term volatility for Bitcoin around the $112,000 mark, while the altcoin season progresses with Ethereum absorbing Bitcoin liquidity.
