I just create an account with cointracking.info. I already input csv from bittrex. For paying tax, I go to Reporting—>Realized and Unrealized Gains. This shows me 2 sections :

1) Unrealized Gain/Loss
2) Realized Gain/Loss

So for the tax purpose, I need to pay the tax for the amount on Realized Gain/Loss in this section. Am I correct?
