Ethereum versus Bitcoin: Can ETH maintain its early lead over BTC in Q3?

After experiencing its strongest relative performance against Bitcoin in nearly a year, discussions between Ethereum and Bitcoin are quietly returning to the focus of the crypto market. Ethereum has fallen behind Bitcoin for three consecutive quarters, but now it is finally turning around-the ETH/BTC ratio rose by more than 5% at the beginning of the third quarter, injecting new vitality into the market.

This further confirms the bullish argument advocated by market veteran Tom Lee for Ethereum. However, as spot Bitcoin ETFs usher in a new round of buying, institutional demand for Bitcoin has also warmed up again. That leaves investors with a big question: Can Ethereum continue to outperform Bitcoin for the rest of the third quarter, or will Bitcoin regain its lead?

BitMine\'s bet on Ethereum continues to increase

BitMine Immersion Technologies made its strongest statement of confidence in Ethereum in the third quarter-purchasing another 42,197 ETH units. This increase brought BitMine\'s total holdings to exceed 5.74 million ETH units, accounting for approximately 4.8% of Ethereum\'s total supply (120.7 million units). The company said the combined value of its crypto assets, cash reserves and marketable securities has risen to approximately $11.1 billion.

BitMine points out that its aggressive Ethereum hoarding strategy is being driven by improved prospects for the proposed CLARITY Act. Forecast market data shows that the probability of passing the bill has risen to about 50%, setting a two-week high. The company believes that as blockchain technology is more deeply integrated into traditional finance, clearer encryption regulations will bring huge advantages to smart contract platforms such as Ethereum. For investors who support Ethereum and Bitcoin, this regulatory optimism has become one of the most powerful positive factors for Ethereum at present.

Ethereum vs Bitcoin

Ethereum fundamentals have not kept up

Although the story is developing well, Ethereum\'s network data warns of caution. The size of Ethereum\'s decentralized financial ecosystem is still lower than it was before the sharp correction in late 2025. Currently, the total lock-in value of the Ethereum agreement is still below US$40 billion, far from the US$89 billion to 90 billion before the decline in October last year. Stability coin activity also weakened. Entering the third quarter, the supply of stablecoins on the Ethereum network fell by more than $5 billion from nearly $160 billion at the end of June.

These numbers suggest that the market may have already factored in expected benefits from regulation into prices, while actual activity has not yet really picked up. In layman\'s terms, the current rise in Ethereum and Bitcoin is driven more by hopes and expectations than actual growth on the blockchain. This doesn\'t mean that bullish logic has completely failed, but it does make Ethereum\'s task more difficult in the coming months.

Bitcoin gets new institutional support

While Ethereum investors look forward to future legislation, Bitcoin is benefiting from an influx of institutional capital. After a long sell-off, the spot Bitcoin ETF has just regained net inflows this week. The latest data shows that more than US$224 million in funds poured into Bitcoin funds in a single day, pushing prices back to around US$63,000. More importantly, BlackRock resumed buying through its Bitcoin ETF products after a long period of outflows. Market reports showed that its Bitcoin products received a huge inflow of US$209 million, which was undoubtedly a boost in the arm after 11 consecutive days of selling pressure.

Although Strategy reportedly sold 3,588 BTC during the same period, Bitcoin managed to hold the important barrier above $64,000. This resilience shows that even if companies reduce their holdings, institutional demand is still sufficient to absorb supply. This constitutes a decisive difference in the tug-of-war between Ethereum and Bitcoin.

ETH/BTC ratio faces its biggest test

Ethereum\'s recent rally in Bitcoin is undeniable. After several consecutive quarters of decline, the ETH/BTC ratio has finally shown signs of recovery. However, historical experience suggests that such continued overperformance typically requires strong fundamental support, such as growth in stablecoin supply and stronger DeFi engagement. Currently, these conditions are still under construction. At the same time, Bitcoin is still attracting institutional capital inflows, corporate reserve needs and growing ETF participation. It is benefiting from solid and proven capital flows.

This makes the game between Ethereum and Bitcoin seem balanced and delicate as it enters the middle of the third quarter. If the CLARITY Act is finally passed and Ethereum\'s on-chain indicators begin to improve substantially, ETH may be able to maintain its lead. But if these developments are not realized quickly, Bitcoin\'s stronger institutional base could once again dominate the market.

Conclusion

The third quarter is still in its early stages. So far, Ethereum has the upper hand, but the winner is far from being announced. Tom Lee\'s optimism is supported by improved regulatory prospects and the currency hoarding strategy of the largest Ethereum company in history. At the same time, the return of Bitcoin ETF funding flows and continued institutional support mean that ETH has extremely limited tolerance space. For now, the battle between Ethereum and Bitcoin is still full of variables-but unless Ethereum\'s fundamentals match all the optimism surrounding it, Bitcoin still seems to have a better chance of winning.
