Our software calculates balances and reports based on the transactions you import. If you loose access to an exchange or wallet and you have no record of your data (CSV/Excel file) there you might have to enter your best guess and create a "Loss" transaction for the remaining coins or coins you sent there.
Here are some recommendations:
- If you have no transaction data at all from not accessible / not available wallets or exchanges we recommend to add those as "Lost" in total for the balances of your coins.
- If you have some transactions missing this becomes more difficult because you can only add those transactions as "best guess", because everything within CoinTracking is calculated based on transactions.
- If you have sent coins via "withdrawal" transaction to a non accessible wallet/exchange you could convert / change this transaction into a "Lost" transactions instead of a withdrawal.
- If those coins have been traded there and those trade transactions are missing the only solution is a "best guess" transansaction here as well.
Unfortunately there is nothing we can do from our end as we need a complete history of the data and only you can do the best guess at what happened.
