I ask this because of the corona virus where people are too scared to hold money.
The issue is that we value btc against the usd and other fiat currencies. If fiat currencies were no longer how would bitcoin be valued...inflation etc? Can't get my head around how it would work.
Just because of the reason that people are scared to hold money or paper currency doesn't means that we must use bitcoin in every transactions. There are online banking in which you can enable to make a payment and transfer without holding your paper money with your own hands. Bitcoin will never be ready to be a world wide currency because no matter what happens, bitcoin will be always second to fiat currency and never will be the top 1. If there will be no fiat currency like USD then probably bitcoin will be no value that's very simple.
