How does it work?

The first step is to download all your transactions from Satang Pro and upload it to Koinly. There are a few ways you can do that:

Satang Pro does not have any API so you will need to download your CSV files from their web site and upload them into Koinly yourself.
If the above method(s) are not possible for you, you can even add the transactions manually through Koinly's web interface.

If you want to import CSV files, you must make sure to import your deposits/withdrawals and trades for ALL years - not just the current one!

That's all you have to do. Don't forget to tag your airdrops/forks so they appear as Income on your generated crypto tax forms!
