How about my government decide not to legalize bitcoin ?
If they don't legalize bitcoin, they don't have the right to apply the tax,right ?
They still not make any restrict policy yet so I can still use bitcoin without paying any tax !
In general, I disagree with you. The governments control everything (inside their countries) and even if they do not recognize Bitcoin, it does not mean that they will not tax their users, there is always exploitation. Their goal is to profit from every financial transaction, that's the issue.
Furthermore, I think if the majority of governments will recognize Bitcoin and cyrptocurrencies in general, then I am pretty sure that the value of taxes will increase, But the positive thing, they cannot control Bitcoin, so they will have many problems. I think the tax problem will always be present in many countries, because the global economy has some crises, so they want to compensate some of financial losses through those taxes.
