Ethereum vs Bitcoin talks are creeping back to the top of the crypto market after Ethereum had its strongest relative performance against Bitcoin in almost a year. Having suffered through three losing quarters against BTC, Ethereum is finally turning things around, with the ETH/BTC ratio jumping by over 5% to start the third quarter.

This has brought closer the bullish Ethereum thesis being championed by market veteran Tom Lee. However, there has been a lot of renewed institutional demand for Bitcoin, driven by fresh buying in spot Bitcoin ETFs.

This leaves investors with a big question: Can Ethereum keep on outperforming Bitcoin for the rest of Q3, or is it likely Bitcoin is going to grab the lead again?

BitMine’s Ethereum Bet Keeps Growing

BitMine Immersion Technologies has just made the strongest vote of confidence in Ethereum this quarter by buying another 42,197 ETH.

The purchase puts BitMine’s total holdings over 5.74 million ETH, about 4.8% of Ethereum’s total supply of 120.7 million coins. The company says that with their combined crypto holdings, cash reserves and marketable securities, now sums up to about $11.1 billion.

BitMine says that their aggressive Ethereum accumulation strategy is being driven by the improving prospects for the proposed CLARITY Act. Prediction markets have just pushed the probability of the legislation passing to around 50%, the highest level seen in two weeks.

The company argues that clearer crypto regulation would hand a huge advantage to smart contract platforms like Ethereum as blockchain tech becomes more deeply integrated into traditional finance.

For supporters of the Ethereum vs Bitcoin trade, this regulatory optimism is now one of the strongest arguments in ETH’s favor.

Ethereum Fundamentals Haven’t Caught Up Yet

Despite the improving story, Ethereum’s network data suggests a bit of caution.

Ethereum’s decentralized finance ecosystem is still smaller than it was before the sharp correction in late 2025. The total value locked across Ethereum protocols is still sitting below $40 billion, which is short of the $89 billion to $90 billion seen before the October downturn.

Stablecoin activity has softened too. At the start of Q3, Ethereum entered with stablecoin supply down by more than $5 billion compared with the nearly $160 billion circulating on the network at the end of June.

Those numbers suggest that the market may already be pricing in the expected benefits of regulation before the activity has had a chance to actually pick up.

In plain terms, the current Ethereum vs Bitcoin rally is being driven more by hopes and expectations than by actual growth on the blockchain.

That doesn’t make the bullish case entirely invalid, but it does make Ethereum’s job harder over the next few months.

Bitcoin Receives Fresh Institutional Support

While Ethereum investors are looking forward to future legislation, Bitcoin is benefiting from institutional capital.

After a long spell of selling, spot Bitcoin ETFs have just started to see net inflows again this week. Recent data showed over $224 million pouring into Bitcoin funds in a single day which helped to push the price back up towards $63,000 level.

Even more importantly, BlackRock resumed buying through its Bitcoin ETF products after a long dry spell of outflows. Market reports suggested massive inflows of $209 million into the firm’s Bitcoin products, a welcome relief after eleven consecutive days of selling pressure

The renewed buying arrived despite continued selling by Strategy which reportedly offloaded 3,588 BTC during the same period. Yet, Bitcoin managed to stay above the important $64,000 level.

That resilience suggests institutional demand is still capable of absorbing supply even when there is treasury selling. For the Ethereum vs Bitcoin tug-of-war, that makes all the difference.

ETH/BTC Ratio Faces Its Biggest Test

Ethereum’s recent gains against Bitcoin are undeniable and finally after all the falling quarters, the ETH/BTC ratio is showing signs of renewed life. However, it is known from history that sustained outperformance of this sort usually requires strong fundamentals to back it up, like growing stablecoin supply and stronger DeFi participation.

At the moment, those conditions are a work in progress.

Meanwhile, Bitcoin is still attracting institutional inflows, corporate treasury demand and growing ETF participation. It is benefiting from solid, proven capital flows.

That leaves the Ethereum vs Bitcoin trade looking finely balanced entering the middle of Q3.

If the CLARITY Act actually gets passed and Ethereum’s on-chain metrics start to show some real improvement, ETH might just have the momentum to keep its lead. But if those developments fail to materialize quickly, Bitcoin’s stronger institutional foundation could once again dominate the market.

Conclusion

Q3 is still in its early days and so far, it has belonged to Ethereum, but the quarter is far from decided.

Tom Lee’s optimism is backed up by improving regulatory prospects and what looks like one of the biggest Ethereum treasury accumulation strategies ever seen. Meanwhile, Bitcoin’s return to ETF inflows and continued institutional support means that ETH’s has a thin margin for error.

For now, the Ethereum vs Bitcoin battle remains wide open but unless Ethereum’s fundamentals start to match all the optimism surrounding it, Bitcoin still looks like it has the upper hand.
