Here's what you need to do
The first step is to download all your transactions from Gatecoin and upload it into Koinly. There are a couple of ways you can do that:
- Gatecoin does not offer 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 even add the transactions manually via Koinly's web interface.
Note that if you want to import CSV files, you must make sure to import your deposits/withdrawals and trades for ALL years and not just the current one!
That's pretty much it. Don't forget to tag your airdrops/forks so they appear as Income on your final cryptocurrency tax reports!
