Here's what you should do
The first - and in most cases, the only - step is to download all your transactions from Exrates and upload it to Koinly. There are a couple of ways you can do this:
- Exrates does not offer an API, so you will need to download your transaction files from their website and upload them into Koinly manually.
- If the above method(s) is not possible for you, you can even add the transactions one by one via Koinly's web interface.
If you want to use CSV files, you need to make sure to import your deposits/withdrawals and trades for ALL years !
That's it. Don't forget to tag your airdrops/forks so they show up as Income on your final cryptocurrency tax forms!
