This is not the final project, it's not even mine, i've doing this to contribute to the community and anyone can join, and give his part of the job. As far as i'm concern, this job has been done so far for the european because i'm from EU ;) but we did consider that bitpay is good for usa/canada, but its doesnt work worldwide , same as xapo/wirex..
by the way i'm not sure if you did understand the concept of flag ;)
