The ETH/BTC ratio has dropped to approximately 0.026, matching levels last seen in March 2016, according to on-chain analyst PlanB. This indicates that Ethereum's performance relative to Bitcoin has regressed to its position from a decade ago. Despite past Bitcoin bull markets in 2017, 2021, and the ongoing 2023/2024 cycle, Ethereum has not shown significant gains against Bitcoin, highlighting its persistent lack of upward momentum compared to the leading cryptocurrency.
