Please proceed with the approval of the BTC ETF. 

It will either be now or later that this is approved and it's pretty obvious that the people who are against this ETF do not own BTC nor do they truly understand what blockchain or cryptocurrency is. 
Market manipulation is a possibility in all forms of investments, including stocks, so that argument is invalid.
