Let's start...
The first - and in most cases, the only - step is to download all your transactions from Coinsuper and upload it to Koinly. There are a couple of ways you can do that:
- Coinsuper does not have any API, so you will need to download your transaction files from their web UI and import them to Koinly manually.
- If the above method(s) is not possible for you, you can also add the transactions manually through Koinly's web interface.
If you decide 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 forms!
