If BTC is to become a reserve currency then it seems to me it would replace/compliment SDR's and precious metals as an international reserve currency and not a national one. In that hypothetical situation BTC solves the Triffin Dilemma for all those who use the USD as a foriegn reserve but the USD would likely still be used in American territory and still backed by confidence (in its ability to be productive and thus pay its debts). Don't think of it as dollars, think of it as gold (especially when gold was broken down in smaller bits and traded in streets or held in the form of gold bars).
