Bitcoin can be international but I do not think we are seeing use in every corner of the globe, yet. Some what not wanting bitcoin to replace fiat straight out either, would prefer side by side.
i see, and i hope so. If bitcoin can use every where. It's make a simple transaction with one currency. :-)
The new generation will bring us new things to us, it is not a dream ,it's true that Bitcoin already international currency and digital too.
