In P2P transactions involving cryptocurrency purchases via bank payment, it's crucial to stay vigilant against potential scams. One common tactic involves scammers persuading buyers to cancel their orders after payment. They may falsely claim that the purchased USDT hasn't been automatically unlocked due to a system error. They suggest either waiting 48 hours for automatic unlocking or switching to manual order processing, with the promise of manual unlocking by a technician.

If the buyer requests a refund before canceling the order, the scammer insists on canceling the order first, creating a deceptive situation where the buyer risks losing their money without receiving the USDT. Therefore, it's advised to never cancel your order once you've made a purchase in P2P transactions involving cryptocurrency through bank payment.
