Serious question about a collapse of the US dollar

How would this impact bitcoin? If tomorrow the US dollar crashed to nothing because they kept printing money and it crashed like every reserve currency does, how would this impact the price? Let’s just say theoretically if 50% of all bitcoin buyers in the world bought with US dollars, even though bitcoin is a type of it’s own store of value, would that not drop the price incredibly? How does bitcoin have value if the currencies of the world dropped substantially? Could you still trade that same bitcoin for gold? Could we quickly trade it for a currency that lasted really well when everything else crashed? I need answers! Bitcoin technically is tied to currency, so would the price of bitcoin just go up in US dollars like crazy but remain a similar price with other currencies that haven’t crashed?
