According to Macau Radio and Television, a man from Macau and a man from mainland China had previously jointly invested in cryptocurrency and suffered losses. They later agreed to trade 640,000 USDT for HK$5 million. On November 6, the buyer deposited HK$5 million into the seller’s account at a casino in Cotai, Macau, but received only 40,000 USDT. The seller then left the scene, citing a need to smoke. The remaining 600,000 USDT was never transferred, involving approximately HK$4.68 million. An investigation by the Macau Judiciary Police found that the suspect did not have enough USDT to complete the transaction and immediately converted the payment into casino chips after receiving it, indicating suspected intentional fraud.
