This is interesting news, even though it's basically still a fiat currency in crypto clothing. It does seem like just a matter of time now when at least one country will try to issue a "true" cryptocurrency to try and boost its economy and escape the dollar paradigm.
If elements within a government could truly rally it's people around such an idea, and incentivise them to maintain the cryptocurrency's infrastructure even under the face of attack it could well stand up to the inevitable efforts to destabilise it by the US dollar system. The ringleaders of such a plan could also still maintain a level of power by just being whales.
Could these be the coups, and the currency wars of the future?
