because with the tax they run, of course it will be free to do, provided the taxpayer is implemented.
What does this even mean? Believe me, I have tried to make sense of it, but there's none to be made.
I agree to pay a tax on profits from bitcoin if the state insures my losses against the fall of the course of bitcoin.
Do you think the state will take this step?
This is the only fair way, but governments rarely go along with it. They'd prefer you to share your income and to ignore you when you're on the loss.
I agree that 10% income tax is fair as it allows for private investors to prosper and at the same time make sure they contribute, without having second thoughts. It ensures that taxes don't become a burden and that people won't try to evade. The higher the taxation the more people will evade, leave the country, use offshore banking, shell companies.
I have no idea why some governments decide to push taxes over 40% when the statistics are showing that when you break a certain level, increasing taxes will not bring any more money to the budget. It will only make people pack up and move out.
