Let's start
The first step is to download all your transaction data from GuldenTrader and upload them to Koinly. There are a few ways you can do this:
- GuldenTrader does not have any API, so you will need to download your CSV files from their website and upload them to Koinly yourself.
- If the above method(s) is not possible for you, you can also add the transactions one by one 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 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 final cryptocurrency tax reports!
