The big question is of course: The only really Bitcoin-friendly country so far is El Salvador, some other relatively friendly ones like Singapore aren't at the same level. Will the US for example join this club as Trump promised? What about European countries (Czech Republic for example)?
You are right because only El Salvador accepts bitcoin as a legal tender while most other countries only apply bitcoin as an investment asset so to smooth bitcoin as a legal tender like fiat currency may not be as easy as imagined.
Each country certainly has a different view on accepting bitcoin and generally they apply tax as an option to gain profit, regardless of how the tax is regulated.
My country does not provide access to purchases using bitcoin like using fiat currency and existing regulations will actually sanction anyone who violates it.
So the decision to accept bitcoin as an investment asset is still better for us for now than trying to fight the regulation.
