Bitcoin's dominance will fall harder than OP's mom on the mailman's crutch when ETF gets rejected coming September. Nothing has changed since the previous ETF got rejected and the current volatility will not help it either.
Poeople want dollar value, not BTC. If Bitcoin ETF is rejected, Bitcoin will tank with nothing in the horizon to push it up. Alts on the other hand will be dirt cheap and ripe for a new alt season. Money will come out of BTC and tether to alts.
