Police in Wanshan District, Tongren City, Guizhou Province, China, recently cracked a cryptocurrency trading fraud case. The victim, Chen, was swindled out of 7,118 USDT (equivalent to over 50,000 yuan) by a scammer named Tan when trading USDT offline. Tan used a "read-only wallet" (an address that can only be used by the user to receive and view funds) and a cash display scam. Investigation revealed that Tan first displayed cash to gain Chen's trust, then immediately transferred the USDT to the "read-only wallet" and denied the fraud. The case is currently under further investigation. Police remind the public that cryptocurrency-related businesses are illegal financial activities with extremely high risks; offline cash displays may be a scam; always verify the authenticity of the wallet address before transferring funds.
