I used CoinTracker this year to help me figure out how to report cryptocurrency on my taxes, and felt like it was a total ripoff. $50 for a two line csv file? Give me a break.
That said, it isn't perfect. I marked several transactions as transfers but it didn't change my cap gains numbers. I added it up manually and the numbers don't seem to add up. Then I checked back later and looks like those numbers are updated later. But why? And by how much time?
