In my country bitcoin has not been legalized by the government but there are applications for crypto currency transactions that have been taxed for each transaction maybe this is a sign that crypto currency will be legalized by the government.
Very strange, can you be more detailed about the tax, is it a self-report or a tax deduction directly from the application?
In a normal country when you are taxed, there is a legal force that oversees and protects your transactions.
Be careful of applications that act in the name of tax fees but actually dredge your assets in a dark way.
