Hi
Actually there is no clear regulation of bitcoin. No official statement from the government yet. Maybe some countries are still doubtful with the existence of bitcoin, because there is no clear regulation then the possibility of bitcoin prices rose even dropped unpredictable.
Thanks
Regulation on the use of bitcoin was already in motion by some countries like the Philippines. Other countries who have seen the merits of bitcoin does not adopted bitcoin yet because they have no clear regulations and policies as to how bitcoin will be used and its limit in their countries. The reason why bitcoin is not supported in some countries is because of the lack of policy as to how they will regulate it and protect their people from the volatility of this currency.
