We can see the price crashing since its release.
I would think that it will take a while for the ETF's to have any impact because they were just released.
As of today the market is recovering and making its position to 42k gain after falling to 38 k so asking if ETF have any impact today? I think this is far from reality at least not today or tomorrow.
but what we need to wait here is the Big boys buying their share before the Halving or after that halving , as they are looking for more discount before pumping the great bitcoin again. this may take time but trust me it is worth it a wait.
