how many country of the world now accept btc?
as of now it can not be told byt we can see that all country will accept it in future as technology modernized and huge amount of people used it.
I do not really know what are the exact countries who are accepting bitcoin as a payment. But it does not really matter, because i know that in the future bitcoin will be accepted by the government and will make a legal currency. And even for now we can still use bitcoin to buy things but we still need to convert it into a real cash.
