Kevin O’Leary has criticized Ethereum's scalability and high gas fees, likening it to a costly toll on a one-lane highway. His remarks have drawn criticism from the Ethereum community, who argue that typical gas fees are significantly lower than O’Leary's claims. On October 17, 2025, Ethereum's price fell 3.9% to $3,870, contributing to a broader $100 billion market correction. Despite the criticism, O’Leary confirmed his continued focus on Bitcoin and Ethereum, citing their market dominance. Technical analysis indicates a potential bearish trend for Ethereum, with prices possibly dropping to $2,500 if key support levels are breached.
