In my opinion to make Bitcoin and cryptocurrency will be huge market, we need Bitcoin ETF because this thing possible become trigger for bull market in crypto. Just like price of Gold that hasbeen bull run after the ETF approved.
Of course we badly need this to happen because the market needs quick cure and this is one good way to push it a bit ahead of the current position it is standing now at. In addition, due to ETF, people will also start investing big which means big push.
