Koinly is the best CoinTracking alternative out there so if you are looking for a service that is faster, better and more accurate - you have found it! We also help you migrate all your data from CoinTracking.
The first step is to download all your data from Cointracking and import it into Koinly. There are a couple of ways you can do this:
Cointracking does not have any API yet so you will need to download your transaction data from their web interface and import it into Koinly manually. You don't need to make any changes to the downloaded file, Koinly will automatically map the columns to ensure all data is imported correctly.
Add the exchanges/wallets/services directly into Koinly and skip Cointracking altogether. Koinly supports all exchanges that Cointracking supports so you should have no issues with this.
If you only have a few transactions and the above method(s) are not possible for you, you can even add the transactions manually through Koinly's web interface.
That's all you have to do!
