Here's what you need to do
The first - and in most cases, the only - step is to download all your transaction data from OOOBTC and upload it into Koinly. There are a couple of ways you can do this:
- OOOBTC does not offer any API, so you will need to download your transaction files from their website and upload them into Koinly manually.
- If you only have a few transactions and the above method(s) are not possible for you, you can also add the transactions manually through 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 previous years and not just the current one!
That's it. Don't forget to tag your airdrops/forks so they appear as Income on your final cryptocurrency tax forms!
