I think the tax on bitcoin is still in fairness, there are many who say that bitcoin tax is expensive but I think it still makes sense and it does not matter if it continues to be applied to bitcoin.
And however bitcoin price at the moment it's higher than before, so the incomes that was earned will also be a high as compared to other jobs in general, it could be the reason the taxes on bitcoin deserve to be a bit expensive.
But still for the countries that hasn't legalize bitcoin including in the country where I live, still free on taxes. But after to cashed it, it's good if we keep paying a taxes to the government, or at least helping the paupers or doing a charity.
