ETH's ETF should still have a relatively strong momentum. The mainstream view is that about 30% of the funds will flow into BTC's ETF.
As for Grayscale's selling pressure, it has also been taken into account.
BTC's market value is now about three times that of ETH, which means that after ETH's ETF is approved, there should be an increase equal to BTC.
In recent market conditions, ETH is also slightly stronger than BTC.
Judging from the current price of ETH, there will be more bulls than bears in the future.
