How did you set up paypal without a bank account? I don't like having mine linked but didn't realize you could opt out of that part.
Depends on what you want to do with PayPal. Since most PayPal want to use PayPal to buy things and/or sell things, they need to either fund their PayPal account by linking a bank account to it, or, for sellers, they will want to link to a bank account so that they can withdraw funds from PayPal. So, in other words, opting out is usually not an option.
