As to your question, if the US dollar hyperinflates (and man, I'm really hoping it doesn't in the near future) then obviously bitcoin is not going to be valued in USD primarily--though it still could, it would just be a mess to do the daily conversions. But think about how payment processors like Bitpay operate. They value bitcoin in terms of whatever fiat currency the item you're buying is priced in, so USD would have to be one of them.
This is making my head spin, because I hate thinking about how much trouble the US dollar is in, and I don't see how the government is going to undo the mess they've put all the US citizens in with all the money printing, stimulus, and everything else. But at least bitcoin isn't affected by any of that--that's the good news, but only if you own bitcoin.
Im in the EU and I check the Bitcoin value in Dollars because most of the crypto
commentary I get is centered on Dollar pricing.
I dont have any answers but its interesting to hear what people think.
So if/when the Dollar hyperinflates I suppose people would continue as they are
