A closely watched crypto market metric is signaling a continued shift toward caution, as investors increasingly favor bitcoin over ether.
The ether-to-bitcoin (ETH/BTC) ratio—commonly used to assess broader market sentiment—declined to 0.02835 on Tuesday, marking its lowest point in 10 months and its weakest level since July 2025.
The drop underscores ether’s ongoing relative weakness. ETH fell more than 2% on the day, compared with a more modest decline of just over 1% for bitcoin. Since reaching a recent high of 0.04324 in August, the ratio has now retreated by more than 35%.
As a measure of ether’s performance against bitcoin across crypto exchanges, the ETH/BTC ratio serves as a key indicator of investor risk appetite. An upward trend typically reflects capital rotating into higher-risk assets such as ether and other altcoins. In contrast, a downward trend suggests a preference for bitcoin, often viewed as a more stable and defensive asset within the crypto market.
The ratio previously peaked above 0.08 in December 2021 before entering a prolonged multi-year decline. Much of the downside pressure through 2024 and into 2025 has been driven by bitcoin’s strong outperformance following the launch of U.S. spot bitcoin ETFs in January 2024, which attracted significant institutional inflows.
The pair eventually hit a low of 0.01770 in April 2025 during heightened volatility linked to President Trump’s “Liberation Day” tariff announcements. It later staged a strong recovery, rallying roughly 135% over the course of 2025, but has since reversed direction. Even after that rebound, the ratio has fallen another 35% from its recent highs.
From a technical perspective, the ETH/BTC ratio continues to trade well below its 200-week moving average, currently at 0.04828, reinforcing the view that ether remains in a long-term downtrend relative to bitcoin.
