What is the impact of bitcoin in a country's financial stability?
The impact will be positive, IMO.
Consider Japan's stand on embracing bitcoin and the blockchain technology.
Even if they are already a progressive country, they still adopt bitcoin because they know it will push their country's economy even further.
I think the impact of bitcoin will be different in each country, in Japan the effects are going to be very positive because they have decided to take a step forward and be one of the countries with the biggest adoption of bitcoin around the world, but I think that in other countries there will be a negative impact, why? Because money will begin to flow outside of those countries to go to countries that are accepting bitcoins like Japan.
Undoubtedly, if some countries legalize the crypto currency, then others will be forced to do the same. The fact is that financial relations between countries have a very strong influence on political relations and I think that this will only lead to positive consequences.
