Presently, USD has more fans than bitcoin. Because everybody is well aware of the value of US dollar. But in future, bitcoin will over take USD dollars.
I doubt that you can talk in this category - I like US dollar therefore I use it. People are using USD not because they are fond of it. but because it is a necessity for them, they have no choice.
You can either use strong FIAT backed by one of the superpowers and hope that it will stay strong or pick lesser FIAT with worse qualities, so there is not much of a choice there, is it?
