Yes, you can. As the Cash App does not rely on the bank account only. The users can send and receive money from the app without a bank account.
The Cash App identifies its users with their email addresses or phone numbers. However, the users can add a bank account to receive money to their bank accounts.
Also, there is no fee to receive the money into the bank account in the Cash App. Alternatively, you can create a unique identifier known as $cashtag from your profile icon in the Cash App.
