Receiving money from strangers on Cash App is highly risky and is the basis for several common financial scams. A frequent tactic involves a stranger sending you money "by accident" and then asking you to send the same amount back to them. Usually, the stranger is using a stolen credit card or a hacked account to send the initial funds. When the real owner of the stolen account disputes the charge, Cash App (or the bank) will reverse the transaction and pull the money from your balance. If you have already sent your "own" money back to the stranger, you will lose that amount permanently with no way to get it back, as Cash App transactions are generally non-refundable. Another risk is "Cash Flipping" scams where a stranger promises to turn a small amount of your money into a large sum if you pay a "clearance fee." To stay safe, you should only use Cash App with people you know and trust. If a stranger sends you money, the safest action is to not spend it and instead use the app's official "Refund" button to return it to the sender without initiating a new, separate payment.
