Yes, for sure, countries in europe, america or this kind of country where the money is stable , paying in Bitcoin would be "just for fun" , but in the countries where the money is not stable (like in venezuela for example) , paying with bitcoin can be very interesting
You have a point. However, do not forget the importance of bitcoin generally which is why most people are adopting it. Although, I understand your point about it being more fun for much more developed countries than some of these third world countries which would end up being more like a safe haven for them if they can start utilizing it.
