The most severe economic crisis, Bitcoin is gaining quite a bit of trust as a currency. In my opinion, Bitcoin doesn't quite fit the bill of a war currency.
The meaning of digital gold for Bitcoin has now found the right interpretation in the public. If gold is complicated to store because it is physical, Bitcoin is more flexible. As a hedge, Bitcoin has surpassed physical gold from the results of scientific research. If you want to believe in it or not, I leave it entirely to you.
You should take a country like El Salvador as an example. Look at the statistics of trust among the residents themselves. As far as I know, the preference is still given to the US dollar. There are not so many Salvadorans who are ready for such changes. And the technology is not so well tested. Still, a country with a more developed economy should be taken as an experiment.
In addition, not all countries allow the use of bitcoin for internal payments. In my country, it is prohibited by law. So, to be honest, I don’t see any positive side.
