You can get free cash on Cash App by refering the Cash Application to your friends, family members. You have to share the link of Cash App and once they download and create a new account you gt $5 on every referral.    

Tap the account balance on your Cash App home screen (shows “Cash & BTC” if your account balance is $0) Press Add Cash. Choose an amount. Tap Add. Use Touch ID or enter your PIN to confirm. More on that below, but, here’s what the process is like for requesting a card in the app: You can’t use the card to draw money from a bank ATM, and you can’t expect overdraft protection. In that way it’s not much different from just keeping a balance in your virtual Square Cash account. It’s because of federal anti money laundering and anti tax evasion regulations. They are required by law to do so. Having that information allows them to confirm your identity so they can report suspicious transfers.
