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.
it is true that the state takes taxes from exchanges, bitcoin deposits and the state still regards bitcoin as a tradable commodity so things like this are very natural because in countries that do not support bitcoin, bitcoin cannot be used to pay for goods, so the owners only can have it just to save.
