This looks good, I haven't yet selected a service for doing my crypto taxes this year, maybe I'll give it a try.
A couple of questions on top of your FAQ:
* A list of what exchanges you support would be nice.
* It's not really clear what sort of tax help you get in the free tier.
* It would be nice to see pricing info without having to sign up.
Also, it's great that you provide a lightweight tracker with no ads (https://www.cointracker.io/prices).
