Yes, you can send money on PayPal without linking a bank account. You can use a credit card, debit card, or your PayPal balance to make payments. However, to withdraw funds from your account, you must link a valid and verified bank account for processing the transaction.  Additional fees may also be associated depending on the type of payment method used, so it's vital to check those details before making any transactions. Also, certain countries may impose limitations and restrictions when transferring money with PayPal, so always make sure you're aware of those.
