ETH/BTC ratio falls to 10-month low as Ethereum continues to underperform Bitcoin

According to CoinDesk, the ETH/BTC ratio fell to 0.02835 on Tuesday—the lowest level since July 2025—and declined more than 35% from its August 2025 high of 0.04324. On the same day, Ethereum dropped over 2%, while Bitcoin fell approximately 1%. The ratio currently stands well below its 200-week moving average (0.04828), indicating a sustained long-term underperformance of Ethereum relative to Bitcoin on the technical chart. Analysis suggests that the continued inflow of institutional capital following the U.S. approval of spot Bitcoin ETFs in early 2024 has been the key driver behind Bitcoin’s outperformance over Ethereum.
