On April 17, Mankiw's legal team issued a document revealing that the virtual currency money laundering gang reached out to college students. A male student who had just entered his junior year was introduced to the business of "purchasing virtual currencies" while looking for a part-time job online. The other party transferred RMB to his bank card account in the mainland. He took the subway to Hong Kong, and then used the money to buy coins at a roadside USDT exchange shop and transfer them to the designated wallet address. A round trip, including travel subsidies, can still earn five to six hundred yuan. One day, his bank card was suddenly frozen by the bank, and he realized that this matter was still illegal. The number of such requests received by Mankiw Law Firm has increased significantly in the past six months, reflecting a trend that cannot be ignored: money laundering gangs are targeting college students and packaging a key link in the criminal chain with high remuneration.
