For now I am postponing my concern about taxes and cryptocurrency. But it is true that if I withdraw any amount now I would lose quite a lot of money, I am sure.
Although I have not declared these cryptocurrencies, I am sure that the day I want to withdraw them, the Treasury will ask where that money came from, which will be a problem.
For now, I live like an ostrich that knows it will have problems in the future with its cryptocurrencies. In addition, the EU is becoming more and more vigilant with this market. It doesn't like cryptocurrencies.
