Zhang San said that he cooperated with his uncle to specifically target U merchants with cash, setting traps for them. The entire case process involved Zhang San connecting with a capital platform, claiming he wanted to invest. The capital platform told Zhang San that if he wanted to invest, he needed to use U for the investment. Zhang San replied that he didn't have any U, and the capital platform told him that they knew U merchants who could arrange cash transactions for USDT.

Then the capital platform found U merchants to come to Zhang San for cash transactions. The U merchant gave Zhang San U, and Zhang San gave the U merchant cash. After Zhang San handed over the cash, the U was not transferred to the capital platform, but instead, Zhang San reported to his uncle, claiming that both his U and cash were defrauded. He then sought his cooperating uncle, and a few days later, the cooperating uncle pressured the U merchant, seizing 2 million cash for the U merchant's alleged crime of concealment. Afterward, they split the proceeds equally.

If this case is real, the actions of Zhang San and his uncle constitute fraud, and if the amount defrauded exceeds 500,000, the punishment is over 10 years, with the maximum being life imprisonment. Some people say that the cooperation between Zhang San and his uncle is essentially a form of robbery. Moreover, Zhang San's actions could also constitute the crime of favoritism and dereliction of duty, as he falsely accused the innocent U merchant of a concealment crime, making Zhang San an accomplice, subject to cumulative penalties, with the maximum sentence being life imprisonment.
