No. USDs are digital tokens used inside the RedotPay app, so they can't be withdrawn to an external wallet or a bank account. You can still use them within the app, though — and what you can do depends on the type.
Your general balance
USDs in your general balance don't expire. Use them for card purchases, card fees, or sending to other RedotPay users.
Your reward balance
USDs from your reward balance can only be used for purchases only and usually expire after 30 days. Anything you don't use by then will expire.
