I've heared that in some countries people have to pay the income tax after buying fiat for their bitcoins. Anyone faced such problem? If yes then how you deal with it in your country?
At one point of view bitcoin is an instrument for investment so ppl buy it willing to get income in their currency.
At the other point it is a currency and it might be used with a purpose of saving. In this case the tax would be stupid.
Its ok to have a tax applied on every bitcoin that is transacted but it must be on the right measures. It must be accurate to the amount of money inside the bitcoin to be equal and fair and be sure that those taxes that are accumulated or gained is use for a god cause and a good reasons.
