Ethereum’s ($ETH) price performance against the flagship crypto asset, Bitcoin ($BTC), is again drawing wider attention. Particularly, the ETH/BTC pair has reportedly returned to the low levels of the year 2016. As per analyst PlanB, this highlights Ethereum’s consistent decade-long underperformance. Currently, $ETH is changing hands at up to 0.026 $BTC, showing a noteworthy weakness in comparison with $BTC over the past ten years.
Not to bash ETH and correct me if I am wrong, but IMO this ETH/BTC chart is remarkable and has important insights:
– ETH has done worse than bitcoin over last 10 years!! Still at 0.026 BTC, like March 2016.
– No ETH bull market pump in 2023/2024, like it did in 2017 and 2021… pic.twitter.com/JOVOQVAWy0— PlanB (@100trillionUSD) June 7, 2026

ETH/BTC Decline to 2016 Levels Against Bitcoin Signifies Fading Competitive Potential
The $ETH/$BTC performance ratio has recently dropped to the levels seen back in March 2016. The development underscores the incapability of Ethereum to replicate the huge $ETH/$BTC rallies that occurred back in 2021 and 2017, specifically as a part of the 2023-2024 cycle. That was the time when $BTC was the leading crypto asset in terms of institutional inflows.
The wider market conditions indicate that the underperformance of $ETH is not only cyclical. Rather, this setup is structural, while $ETH is struggling to maintain its momentum. As $ETH/$BTC is reverting to its decade-old levels, the broader market narrative underscores the leading altcoin’s fading comparative potential against the top crypto asset.
Particularly, following the sharp surge in 2017, the ratio of Ethereum ($ETH) against $BTC dropped notably, only to see a provisional recovery during the cycle between 2021 and 2022. Nevertheless, the data also discloses a gradual decline in the trajectory between 2023 and 2026. So, while returning to the 2016 levels, $ETH has failed to provide a sustained bull rally when compared with Bitcoin ($BTC). Therefore, the historical data points out challenges that $ETH is facing in order to sustain parity with $BTC.
Missing 2023-2024 Opportunity Indicates $ETH’s Structural Weakness
According to PlanB, Ethereum ($ETH) missed a noteworthy opportunity during the massive 2023-2024 cycle. At that time, the top altcoin was anticipated to capitalize on wider altcoin enthusiasm. Rather, the dominance of $BTC in institutional and ETF portfolios left $ETH behind. As a result, Ethereum’s slump to the 2016 levels is more than a historical echo, as it denotes a stark reminder of the uphill battle that $ETH is fighting to sustain its long-term potential against Bitcoin.
