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?
I think there are a lot of countries with no bitcoin taxes,because they just cann't control it or They do not care at this stage/they do not know about it.For example in my country,In Republic of Georgia there are no bitcoin taxes for people,But there are regulations(not strict,there works liberal approach for such issues) for legal entities.So you can easily find another countries in google,despite the fact you need to take into account every institutional regulations.But if you mean where are regulations about zero taxes I just remember America and Germany.
