But that your government recognizes bitcoin as a currency? I doubt it. Your income in bitcoins according to the law is not revenue. If you buy goods with bitcoin it does not fall under the tax base. If you exchange them for your currency, then taxes will have to pay.
Bitcoin or any other crypto currency is falling under the tax base, because of it's actually profit. I really don't know how the government is going on to out watch all this digital profit, bit I am sure they are creating their plans about it. Maybe something like local wallets where you will have to fill all your private information and banning other kinds of wallet. Don't know.
