I worked for banking software for some 3 years (a long time ago), but none of that was some exotic crypto currency at all. The system itself was just that banks way of doing it, and real transactions with real other banking systems. If asgaria was recognized as its own nation and banking entity, NONE of this complexity is required. Should we have our own bank? YES, that way no one on earth can hold Asgardia funds hostage. Does it need to be a crypto currency? not necessarily.
