According to the Federal Trade Commission, scammers pretend to be public officials, law enforcement agents, or employees of local utility companies.

Scammers also use dating apps and pretend to be potential romantic partners or contact victims to announce that you've won a prize.

No matter how it starts, the scammer always ends up asking for money,' says the US Federal Trade Commission.

If the user falls into Spiel, the scammer will tell them to withdraw some cash and go to the encrypted ATM.

The commission says at that moment the QR code is triggered, as they share the QR code of their wallet address with the victim.

For this reason, once the victim scans the code, the purchased crypto assets will be transferred to the fraudster's account.

This is the main thing to know, said Christina Miranda of the Federal Trade Commission's Division of Consumer and Business Education. No one from the government will tell you to pay them. With digital currency, if someone does, it's a scam every time.
