I suspect that all of these people will accept it soon enough.

There is a generation who will not adapt crypto at all, and there is an other which will do only partially. Unless their right will be still harmless to use fiat they will not want anything else. Within their world there is no need digital currencies, it’s not more simple rather complicated for them to have a digital wallet. To accept or put up are different.

There were ppl who never tried a car, for them their horse was fine for their whole life.
