Here's what you should do
The first - and in most cases, the only - step is to download all your transaction data from IDCM and upload it to Koinly. There are a few ways you can do that:
- IDCM does not offer any API, so you will need to download your CSV files from their web UI and upload them to Koinly yourself.
- If you only have a few transactions and the above method(s) are not possible for you, you can also add the transactions manually via Koinly's web interface.
If you decide 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 generated cryptocurrency tax forms!
