Not sure what you are really asking as the words seem vague, but all I know is that all you gave to pay for is capital gains/income tax in the event of a profit. If not, then tax is basically nil for you (at least here in my country). At best, you can consult the ToS and Legal page of Bittrex. I know for certain that the fees they ask already covers what you are asking, and as for domestic taxes, you need to file it yourself as capital gains/income tax and the rest is pretty much straightforward from there.
Yes I will pay income tax (laws here) in my country. So I have not to pay additional tax in the US, when trading on Bittrex?
Thats the question. Because the trade happens in the US if i trade on Bittrex.
And US dont get any income/capital gain tax because I pay them in my country already... .
I think this is all covered by the double taxation prevention contract (i dont know the exact name) between the US ans other countries to prevent such double taxations.
But iam not completely sure ...thats why iam ask.
To pay the right taxes in my countrys for upcoming gains on Bittrex is clearified .... but not when iam trading on crypto exchanges located in other countrys.
