In my country you only are obligated to pay 18% tax from your income, whether it was from cryptocurrencies or anything else. This tax is to high though in my opinion and makes a lot of people move out.
I think 18% is not high. In my country,Japan tax rate of the profit from stock trading is 20%. And people are also asking to apply a tax rate of 20% for profits from crypto currency trading. Currently, the profit from trading of crypto currency is combined with other profit, such as salary, and be taxed by following tax rate. Very high.
