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. :-)
I think bitcoin is everywhere, it's the people who uses it is not all. Maybe there's a time for that the bitcoin will be know international currency as long as we kept on encouraging others to join us and have some financial support for them also.so that bitcoin will more boom and it can rise up to the highest .
