On-chain analyst Murphy outlines a liquidity-based metric where the ETH traffic share equals the USD value of ETH flows divided by combined ETH and BTC flows across trading venues; this on-chain data gauge rose to a cycle-high 48% on August 15, indicating nearly half of exchange flow concentration in ETH. Historically anchored to a historical average near 26%, the metric has shown strong covariance with the ETH/BTC exchange rate, suggesting shifts in capital allocation between the two dominant assets can precede relative price performance.
Past episodes — notably September 2020 and the post-May 17, 2025 break above average — demonstrate synchronized rises in traffic share and the ETH/BTC rate. With the pair currently around 0.04 versus the 2021 peak ~0.08, the divergence highlights potential revaluation dynamics if institutional funds sustain inflows; this analysis is provided for educational purposes and not as investment advice.
