Many many many years to come before it becomes an international accepted currency, probably not even in our lifetimes, but I hope so though.
I also had little doubt that bitcoin could become an international currency in the near future , I just hope the value of bitcoin getting up
I think, at this moment in time that Bitcoin is more of an international currency than any other on the planet. It is not that widespread and not widely accepted, HOWEVER, I am sure that it is the one currency that is used in the most countries at the same time than any other.
