You're right. This has almost nothing to do with the ETF. The main reason is it was already rejected once.And the chance it will get approved in a second attempt by review is ridiculously small!!
Therefore the second annoucement by the SEC, very likely another rejection, won't have any significant impact on the price.
Price might not necessary spike because of that, but confidence in bitcoin's future potential might be bolstered.
I belive that we will have bitcoin ETF someday, in due time.
In a sense you are correct. Maybe the second review give investors trust and confidence in bitcoin. They see good potential in bitcoin that's why they have put money in the ecosystem. If ETF will be rejected, I think they will still stay with bitcoin because the price is going up. So its a win-win situation for us casual holders and big investors.
