I only know of Denmark and Germany but only if you have held them for more than a year I believe.
Does anyone know of any others?
It is very fortunate for these countries that their Bitcoin earnings will be free of tax meaning their earnings still will be intact to spend specially for their daily needs. Other countries that 0% tax are Singapore, Belarus and Slovenia but there are still countries that free of tax because Bitcoin is not legal and not ban like Philippines in which it is very lucky for them as they will enjoy their Bitcoin profit without tax too.
