Let's begin...
The first - and in most cases, the only - step is to download all your transactions from Dcoin and import them into Koinly. There are a few ways you can do this:
- Dcoin does not offer an API, so you will need to download your transaction files from their web interface and import them into Koinly yourself.
- If the above method(s) is not possible for you, you can even add the transactions one by one via Koinly's web interface.
If you want 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. The only other thing to be vary of is to tag your airdrops/forks so they show up as Income on your final cryptocurrency tax documents!
