Although bitcoin is not that an "official" currency yet, one can say that a country having most of its citizen engaged with a trending, highly-anticipated financial support that should help the country's economic and trading aspect to boom and improve.
Not yet proven. Japan already embrace bitcoin but they are one of the strongest company. Other 2nd or 3rd world country started to be friendly to bitcoin but we don't know the effect to their economy as of yet.
We say this, thought of this, but in reality it is hard to imagine how can bitcoins fuel and power up a country and its economical stabilization with almost all of its citizen engaged with it? First of all, it is not an official currency which will give problems regarding to the trading and cycle of currency within a country. And lastly, the management and utilization of it is also a problem.
So, how can we say that the bitcoins are a support to a country and its economy? Is it even possible? How will that happen?
Its hard to say. Bitcoin can gave people a lot of purchasing power which in term help the the country economy, but again there's no solid proof as of today. Or bitcoin can be used as cross-border-payments, specially in Asia wherein millions to pour to the country and using bitcoin as remittance.
No there is already a proof, japan today is using bitcoins to improve their own economy and it was the reason why their people are having a wealthy life in their country.
