We're done with the covid issue and if not, things are way better now. If this is the only reason you see to why Bitcoin would be an alternative mode of pyment, then it's a no. First of all there are fiat based digital currencies which are more supported by different countries because they can regulate it unlike with cryptocurrencies. In the future, I believe that this technology would be acknowledged by more countries as an alternative payment but it'll be a long progress before such thing happen given that there are still issues being considered to do so, at the present.

This will happen after 100 Years for Sure. In every country there's always a place where cash/fiat never dies - Public Market, Transportation etc etc. Venezuelan Bolivares is a living Testimony of a corrupt government, and a country without cash will just be an Imagination. Bitcoin would be nothing without cash.
Coexistence is more likely and more possible to happen if things would go smoothly for this industry.Some banks are now giving opportunities and consideration to this blockchain so I guess things aare still improving for this industry.
