I do not think there is an exact day when the SEC will decide on bitcoin ETF because there is some news telling that September 30 is the postponed date where the SEC is going to decide whether Bitcoin ETF will approve or not.
Anyway, I think we don't need bitcoin ETF because according to other enthusiasts that bitcoin ETF is made to play the price of bitcoin and I think they create it for pump and dump.
Here is a video that we do not need a bitcoin ETF
