I don't think ETF will get approved by SEC they were just playing with the bitcoin prices and in the end they will look to dump the prices again so we don't have to care but about ETF's approval this can help us to stay away from their trap.
I believe that btc will get approved by SEC ,especially now big financial institutions are doing everything humanly possible to get btc etf approved.
They may delay it but cannot deny it for a longer time.
At a point ,they won't have any genuine reason to give the world for not approving btc etf.
