I thought that Bitcoin might become one of the currencies used by people when the fiat systems collapse, but I think this will only be a minor use. I believe that fiat cash will be used for a while, and silver coins could become a longer term solution. Of course it all depends on the cryptos that are introduced by the various governments, and whether there will be any trust in them.
Again and again, Bitcoin is one alternative payment method. Bitcoin is only for Bitcoin wallet owners. And people who know about the use of crypto. And that is the reality. It takes something to introduce Bitcoin and crypto as a whole to the laity.
