Now you remove the credit card, or it becomes invalid. You can still send money, withdraw money to your bank account, add funds to your PayPal account from your bank account, and receive payments. However, you can only send eChecks, not "instant payments".
Now suppose never did remove the credit card, but instead you removed the bank account. You can still send money ("instant payments", but no eChecks of course), but you will be limited to your $2000 lifetime sending limit. If you have already sent more than $2000 with the account you will not be able to send any more (until you add a bank account again). You can't withdraw to a bank account, but you can request a paper check.
The above illustrates the general case with PayPal accounts. The details may vary for specific accounts.
