There are lots of countries who accept bitcoin payments. According to Prableen Bajpaj in his article entitled 'Countries Where Bitcoin Is Legal & Illegal (DISH, OTSK)', bitcoin is anonymously used in transactions that can happen anytime and anywhere. They may used it to buy things, sell illegal goods like weapons and drugs and others. Here are the countries listed to be said that say 'okay' for bitcoin.
United States, Canada, Finland, and Australia.
In United States, they positively accept it yet several agencies in their country prevent the usage of bitcoin. In Canada, they used bitcoin for exchanges and service businesses. In Australia, they used it for mining, trading and buying bitcoin.
May I add something, Japan had very open for the Bitcoin and the Cryptocurrency. They have legalized the use of it, but the mass adoption is still slow.
