币界网报道：Author: Deng Xiaoyu In virtual currency activities, how to safely "withdraw money" is an enduring topic. U card provides a convenient way to consume without withdrawing money, which is very popular among people in the currency circle. Many people have started the U card promotion business, but there are policy risks in promoting it to users in mainland China. What is U card? U card is a USDT bank card, which uses the price stability of USDT stablecoin to provide users with a stable and convenient means of payment. Users can consume in offline physical scenarios, because the price of USDT is stable and suitable for daily payments. Promotion risks Some promoters are not authorized by the project party and only undertake the card opening needs of mainland residents to earn service fees. There are many risks: According to relevant announcements and judicial decisions in the mainland, using U card for virtual currency trading is likely to violate the foreign exchange management system, and the promoter may constitute an accomplice to the crime of illegal business operation. Promoters should review the legality of the issuing institution, avoid promoting unlicensed or niche service providers, and prevent fund security risks and fraud charges. Promoters collect mainland user information to open cards, which may violate foreign judicial regulations and personal information protection laws, and information leakage may constitute a crime. Assisting in card opening may involve crimes such as money laundering, and promoters may be deemed to have known criminal intent. In summary, U Card, as a stable currency bank card, may become a lifestyle in the future, but current promotion needs to be cautious. Mankiw does not recommend promoting U Card to users in mainland China, as there are policy risks. Even if supervision is relaxed in the future, promoters should not participate in assisting card opening to avoid assuming the responsibility of card issuer review.
