How about next time before you post crap here you learn some basics English, read a bit about bitcoin and shut up if you have only stupid things to say.

I think Bitcoin is not recognized officially all over the world so some countries still prohibit Bitcoin in business.
To deal with this situation the world government must have a positive view on Bitcoin then Bitcoin can be globalized.
The world government should do it?
