Laughed hard that I thought OP is making sense on his post and then he will say
Even without regulation in your country you still have to pay taxes. Income tax in general covers all even if it is illegal that is why drug cartels are laundering money in a form of "legit" businesses in order for them to be able to spend their illegal money. BTC might be neither legal or illegal in your country but you still have a duty to pay taxes even if there are still no laws covering about it. You might be earning through trading and mining but they are still covered by your taxes through capital gains and income tax respectively, there is no special tax for BTC as you already have one.
