I am new to Koinly. Today I downloaded my CSV files from multiple exchanges and uploaded them all into my account. I then paid for a tax report that is off by hundreds of thousands of dollars. Is this not stating realized gains and losses but just paper gains and losses? This is extremely disappointing after spending hours retrieving and uploading 2.5 years of CSV files into this account. There are over 20,000 transactions so I cannot manually assess where this program is making errors. Is there a way to fix this or did I just waste a few 100 dollars and waste part of a day on this?
Hey @Dave_R 
Our capital gains calculation is only ever based off realized gains and losses - not unrealized.
What makes you think the calculations are inaccurate? Have you run your own calculation of the numbers for 20k transactions, and comparing them?
The gains are calculated based off your data import and also the cost-basis method which is used - so if you believe it’s incorrect, please highlight specific transactions so we can troubleshoot.
There is little we can do to assist you on the forums as we need access to your data. We serve millions of users who find the application just fine, as well as CPA/Accountants who rely on it to file for their clients - so I would be very surprised if anything was calculated “incorrectly”.
Please email us on support@koinly.io so we can discuss this further. 
Best wishes
