A Paypal account is a "virtual" bank account. You can send and received money using only your primary email address. (usually the one you use to login into that account)
However, any Paypal account requires a real bank account or a credit card. If you don't have a credit card, you can attach a bank account to your Paypal account. All the money you make with your Paypal account can be sent to your real bank account.
