BitMine added about 17,000 Ethereum (ETH) while ETH outpaced Bitcoin (BTC) in Q3, sharpening focus on whether the ETH/BTC ratio can break above 0.03 in Q4.
Key Points:
- ETH is on track for more than a 70% Q3 return, compared with 43% for Bitcoin.
- The ETH/BTC ratio is testing 0.03, a level it has failed to reclaim since the October crash.
- BitMine added roughly 17,000 ETH as broader altcoin participation strengthened.
Ethereum Q4 Setup
Data showed ETH on track to finish Q3 with more than a 70% return, compared with 43% for Bitcoin, giving Ethereum more than 1.5 times Bitcoin’s quarterly gain. The performance gap is substantial.
That momentum now hinges on the ETH/BTC ratio, which is trading around 0.03, a resistance level Ethereum has failed to reclaim since losing it before the October crash. A sustained move above 0.03 would signal that Q3 relative strength is carrying into Q4, when Bitcoin has historically had the edge. Ethereum has not outperformed Bitcoin in Q4 since 2021.
Institutional flows remain tilted toward Bitcoin, with SoSoValue showing more than $6 billion of Q3 net inflows into Bitcoin ETFs, more than twice Ethereum’s total. Bitcoin funds took in $3.1 billion in August alone.

BitMine ETH Rotation
Against that backdrop, BitMine added another 17,000 ETH, while Strategy bought 1,665 BTC and Strive purchased $94.5 million of Bitcoin, lifting its holdings above 27,400 BTC. BitMine Chairman Tom Lee said institutions remain underweight crypto and he expects them to increase exposure in the final months of 2026. Corporate buying is supporting both sides.
Broader market signals also point to stronger altcoin participation, with Blockchain.center’s Altcoin Season Index above its mid-August high of 61 and Bitcoin dominance down nearly 1.7% this month. ETH is also outperforming BTC on the monthly timeframe, reinforcing the case for a possible rotation if the ratio clears resistance. The breakout is not confirmed.
That combination matters because corporate accumulation is occurring alongside improving altcoin breadth rather than as an isolated treasury trade. The ratio still needs confirmation.
Ethereum’s current setup follows a Q3 in which its return exceeded Bitcoin’s by more than 27 percentage points, reversing the relative weakness seen in recent Q4 periods. Since 2021, however, Bitcoin has outperformed Ethereum in every fourth quarter, making the 0.03 ETH/BTC level a key test of whether 2026 breaks that pattern.
