Here's what you should do
The first step is to download all your transaction data from BitMarket and upload them to Koinly. There are a few ways you can do that:
- BitMarket does not offer an API, so you will need to download your transaction 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.
Note that if you want to use CSV files, you must make sure to import your deposits/withdrawals and trades for ALL previous years - not just the current one!
That's it. Don't forget to tag your airdrops/forks so they show up as Income on your generated cryptocurrency tax documents!
