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
That's just a part, not all. I think the governments probably already know about the existence of Bitcoin and they believe it but they do not want to recognize and support BItcoin in their country because they fear that BItcoin will affect the economy their sacrifice. Bitcoin is the currency of freedom, anyone can use it, just got internet, it has no head control. They fear that it will be impossible to fully control BItcoin, failing to provide clear Bitcoin regulations in their home country.
