When you withdraw money from your Groww Balance, it will automatically go to your primary bank account.
If you've registered more than one bank account with Groww, you can choose which bank to send the money to on the withdrawal screen.
To add another bank account, click on the 'ADD BANK' button and then 'ADD ANOTHER BANK'. Make sure to double-check your bank account details before proceeding with the withdrawal to ensure everything goes smoothly.
