recently the Tianjin police disclosed a new type of scam called "virtual currency investment plus offline transactions". The police found that the so-called "U coin" investment was just a cover-up, and the so-called "U merchant" was a team helping fraudsters transfer funds. After investigating, it was found that since July this year, criminal gangs have committed more than 10 cases of running points under the banner of "U merchants" in Tianjin and its surrounding provinces and cities, involving more than 500,000 yuan. Currently, four members of the gang have been arrested by the Wuqing District People's Procuratorate of Tianjin in accordance with the law.
