I don't think that changes anything. Even if you are earning Bitcoin it foes not exempt you from paying taxes as it is still counted as income from both earning and capital gains. Also i don't think that method will be legal as from what I know it is a standard procedure to Foreign Fiat Currency to be converted in your local Fiat Currency equivalent, which will also apply to Bitcoin. Remember that we cannot tax other currency we must convert it on our own to make it proper.
