Technically speaking, ETH/BTC last experienced a robust quarterly rally in Q3 2025, rising 53% to record its largest quarterly gain since Q2 2021. However, sellers eliminated 50% of those gains as the rally experienced a loss of momentum. This indicates that the rotation was short-lived, as capital persisted in flowing into Bitcoin. Against this backdrop, the ratio’s 5% rally so far in Q3 seems premature to validate a sustained shift from Bitcoin into Ethereum. Simultaneously, Bitcoin dominance is once again approaching the critical 60% resistance level, having increased by 1.5% in July, indicating that capital may already be shifting back into Bitcoin.
That said, Eric Trump’s recent post on X indicates a contrary perspective, endorsing Ethereum’s rally. Meanwhile, the on-chain data presents a comparable narrative. Ethereum’s outperformance against Bitcoin isn’t occurring in a vacuum. Institutional positioning remains supportive of the trend, as Ethereum ETFs have garnered more than $128 million in net inflows this month, surpassing Bitcoin’s performance. Meanwhile, Ethereum’s DATs are experiencing a recovery, which adds additional support to Ethereum’s recent strength.
With that said, it may be premature to dismiss the current ETH/BTC uptrend as merely another short-term rotation. The larger inquiry pertains to whether informed investors are strategically positioning themselves in anticipation of a structural shift that the wider market has not yet accounted for. A significant catalyst could be bolstering the institutional shift towards Ethereum. Tom Lee highlighted Robinhood’s recently introduced Layer 2 chain as a significant differentiator, describing it as a breakout product that has already produced more volume than numerous established DEXs. More importantly, the network utilises ETH as its native gas token and settles on Ethereum Layer 1. As activity on the chain expands, each transaction contributes to Ethereum’s ecosystem, reinforcing the long-term demand narrative for ETH.
The on-chain data supports this assertion. As illustrated in that chart, the volume of ETH transitioned from Ethereum Layer 1 to the Robinhood Chain has experienced a nearly tenfold increase over the past week, exceeding $100 million. That indicates users are actively reallocating liquidity into Robinhood’s Layer 2 ecosystem, with ETH becoming the primary asset for gas, settlement, and on-chain activity. In this context, Ethereum’s outperformance against Bitcoin could signify more than merely another rotation. Instead, the move appears to be increasingly motivated by enhancing fundamentals, as institutional inflows, increasing Layer 2 activity, and escalating on-chain demand persist in bolstering Ethereum’s long-term investment rationale. If that trend holds, the ETH/BTC breakout could signify the initial indication of a wider capital rotation into Ethereum throughout Q3.
