Viewer Mrs. Xu wanted to exchange 120,000 USDT of virtual currency into Hong Kong dollars. She searched online and found a physical money changer in Mong Kok for the transaction. Mrs. Xu went to the money changer in person to make the transaction. She first transferred 300 USDT and then transferred the remainder. However, the person in charge did not respond after the transfer, and the money changer staff also ran away immediately. Dong Zhang arrived at the scene and found that the place was empty. Mrs. Xu felt helpless that she was deceived even when she met in person.
