I've tried out a few "crypto tax services", and (IMHO) Taxbit comes out on top for a couple of reasons: 1. They seem to have the best integration / selection of exchange / wallet API support. 2. Their customer service is great; if you need help importing a CSV into your account, they can help you out with that. They're actively improving the product with NFT support and they're starting to build out more of a "portfolio" feature, which is cool. I'd give 'em a try!
