CoinTracking supports the import of Bittrex transactions.
You can perform an import either via the automatic API integration or via a manual CSV import.
For API imports you need to create an API key that you can insert into CoinTracking. You can learn how to do this here.
Follow the import instructions to download a CSV file from the exchange or wallet and then upload it to CoinTracking to import all transactions.
Please note, that the Bittrex export data does not include any deposits or withdrawals.
If you have deposited or withdrawn currencies from or to Bittrex, please enter them manually on the Enter Coins page.
