I had to buy 4 years of reports on Cryptotrader.tax. I see on my reports that I have a number of actions where my Cost Basis amount was $0.00. Why would that be?? I paid for every coin that I traded to, either by trading from another coin or buying with cash. I suspect that incorrectly increases the amount of Capital Gains for me. Is it possible to correctly have zero in my Cost Basis for a transaction? Doug
