Do you want to naturalized in such a country? https://bitcointalk.org/index.php?topic=5400730.msg60254211#msg60254211 though a lot of country reject the use of bitcoin while the ones that adopted I believed is not taking tax. The countries I have heard that taken bitcoin as their legal tender is only two. El Salvador and Central African Republic and they are tax free Countries on bitcoin. But the ones that are trying to adopt bitcoin as their alternative currency on the digital space for exchange are contemplating on the adoption of the coin. They are still thinking of a possible way to collect tax from users of bitcoin in their Countries. I do not think they can collect tax from the users of bitcoin because when goods and services are exchanged between two or more persons, they users
use direct payment method which is called p2p. And with that, government tax has been bypass.
