as far as I know, Japan and Singapore are the countries that accept Bitcoin the most,
Japan is very concerned about technology and Singapore is one country with an open mind, both countries are very accepting of Bitcoin even though many other countries reject it and afraid.
Usually developed countries in Asia are always more advanced in terms of technology, able and willing to adopt the progress. as well as bitcoin they are very supportive of the convenience provided. to my knowledge Japan and Singapore are the most ready countries and there are some countries that have also been able to accept but are still constrained by regulations that have not yet been formed.
i have visited singapore a lot of times , they are the most crypto friendly in asia.
a lot of crypto project registered and operated there. even though i don't see there is a lot of restaurants or bar that publicly reveal that they are accepting bitcoin as a payment, i am sure there is a lot of merchants willing to accept bitcoin or any other cryptocurrency as a payment processor if you talk and ask them.
the bitcoin atm also pretty much available near some malls , forgot which one but i found 3 of them.
singapore simply a very friendly for those who looking for settling crypto business.
