If someone anywhere in the world, sees potential in this coin, can accept it. It could be a universal coin as coin_trader said.
However the primary focus remains on Pakistan.
just tell me one reason why anyone would prefer to use Pakcoin instead of their own countrycoin
Anyone using Pakcoin outside Pakistan has to find his own reason.
The post you are quoting clearly says " If someone anywhere in the world, sees potential in this coin, can accept it." If you dont see any potential,dont use it.
As a trader you want to use tge coin that gives you profit without caring about its name and for which country it is made for.
