Here's what you should do
The first - and in most cases, the only - step is to download all your transaction data from Escodex and upload them to Koinly. There are a couple of ways you can do that:
- Escodex does not have any API, so you will need to download your CSV files from their web interface and upload them into Koinly manually.
- If the above method(s) is not possible for you, you can also add the transactions one by one via Koinly's web interface.
If you want to use CSV files, you must make sure to import your deposits/withdrawals and trades for ALL previous years - not just the current one!
That's pretty much it. The only other thing to keep in mind is to tag your airdrops/forks so they show up as Income on your generated cryptocurrency tax reports!
