This has always been more of the dream of BTC than the reality. Transferring BTC around can cost 0.1 - 0.4% which becomes quite expensive. The cost of a wire transfer from Canada to the various countries I make them is a flat $36 - though receiving fees can be as high as $15 (CAD). That means that BTC only makes sense if you're transferring less than $5100.
But moreover, BTC back to fiat is significantly more expensive than "expensive" currency exchange with usually levels as high as 3%
