So there is only two routes for the US dollar: Become worthless and irrelevant like other hyperinflated currencies (Weimar Germany and Zimbabwe) or integrate into Crypto. If the dollar heavily integrates into crypto and even the stock markets become 24-7 like the current crypto markets are then the dollar might be able to flip crypto. I doubt this scenario will happen because Wall Street is set in their ways. At a minimum if the dollar and private investment firms continue to embrace crypto ever more (more ETF, Funds, etc.) and dump more of the hyperflated money into the crypto market thereby temporarily staving off collapse due to hyperflated printing of the money supply.
