Here's what you should do...
The first step is to download all your transaction data from CoinHe and upload them to Koinly. There are a few ways you can do this:
- CoinHe does not offer any API, so you will need to download your CSV files from their web UI and import them to 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 one by one 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 !
That's all you have to do. Don't forget to tag your airdrops/forks so they appear as Income on your final crypto tax documents!
