The backup/recovery QR code is dynamic. Using the code will restore your portfolio to its last known state.
The backup is NOT a snapshot. If you delete portfolios, coins, or transactions, it will also be updated in the backup and the items deleted are not recoverable!
PRO TIP: We cannot reverse any changes you make to your portfolios, coins, or transactions for you. You will need to manually re-add/correct the changes you made to fix your portfolio.
PRO TIP 2: The same applies to your Delta account. You can log back into your Delta account through eToro to regain access to your portfolio(s) but this is dynamic as well. You can learn more about Delta accounts here.
