Ethereum (ETH) has historically struggled to maintain its outperformance against Bitcoin.
On the technical front, ETH/BTC last posted a strong quarterly rally in Q3 2025, where it surged 53%, marking its largest quarterly gain since Q2 2021. However, sellers erased 50% of those gains as the rally lost momentum. This suggests that the rotation was temporary, as capital continued to flow into Bitcoin.
Against this backdrop, a 5% rise so far in Q3 seems too early to confirm the ongoing rotation from Bitcoin to Ethereum. Meanwhile, Bitcoin dominance is once again heading towards the key resistance level of 60%, where it rose 1.5% in July, suggesting that capital may indeed be returning to Bitcoin.
However, Eric Trump’s recent post about X points in the opposite direction, supporting Ethereum’s rise.
Meanwhile, on-chain data tells a similar story. Ethereum superiority vs Bitcoin (BTC) It does not happen in isolation. The institutional situation continues to support the move, with Ethereum ETFs attracting more than $128 million in net inflows so far this month, outperforming Bitcoin. Meanwhile, Ethereum’s DATs are recovering, adding further support to Ethereum’s recent strength.
However, it may be too early to write off the current ETH/BTC uptrend as just another short-term spin. The bigger question is whether the smart money is ahead of a structural shift that the broader market has yet to comprehend.
Ethereum’s latest catalyst puts the ETH/BTC ratio in the spotlight
The main catalyst may be the strengthening of institutional rotation in Ethereum.
Tom Lee pointed to Robinhood’s recently unveiled Tier 2 Series as a key differentiator, calling it a premium product that has already generated more volume than many established DEX platforms. Most importantly, the network uses ETH as its native gas token, resting on Ethereum Layer 1. As on-chain activity grows, each transaction feeds back into the Ethereum ecosystem, fueling long-term demand. issue For Ethereum.
On-chain data supports this. As the chart below shows, the amount of ETH bridged from Ethereum Layer 1 to the Robinhood chain jumped nearly 10-fold over the past week, surpassing $100 million. This indicates that users are actively moving liquidity into Robinhood’s layer 2 ecosystem, with ETH emerging as the network’s primary asset for gas, settlement, and on-chain activity.
In this context, Ethereum’s outperformance versus Bitcoin may be more than just another spin.
Instead, the move appears to be increasingly driven by improving fundamentals, as institutional inflows, growing layer 2 activity, and rising on-chain demand continue to bolster Ethereum’s long-term investment case. If this trend continues, the ETH/BTC breakout could be the first sign of broader capital turnover in Ethereum during Q3.
Final summary
- Ethereum’s rally against Bitcoin is supported by exchange-traded fund (ETF) inflows, stronger on-chain activity, and Robinhood’s second-tier ecosystem.
- If these trends continue, the ETH/BTC breakout could signal a broader shift of capital to Ethereum in Q3.
