And even if they don't, if you then want to buy tomatoes at your local market, how are you going to buy lira for your BTC without an exchange (or equivalent)?
At 100 milion you will have access to people you and I dont who know schemes better than bitcoin to buy massive foreign cureencies..
Such as simple as buying a property in london
