You can connect your exchange accounts to your CoinStats app for automatically syncing balances and tracking your crypto without adding them in manually.
Here is the list of the supported exchanged for auto-sync feature.
Please note that we currently don't sync past transactions for all the exchanges and in some cases it starts calculating profit/loss from the date you connected the exchange to your Coin Stats app.
You can find more info on how to sync your specific exchange here.
Here you can request a new exchange to be added for API sync feature.
Feel free to contact our support if you're having more questions.
