A man in the United States has been sentenced to six years in prison and ordered to hand over millions of dollars for running a so-called "no questions" cash-for-bitcoin service, Internet reported. Federal Court Judge Richard Stearns in Boston announced on May 22 that Trung Nguyen of Danvers, Mass., was sentenced to six years in prison, subject to three years of supervised release after completing his sentence, and ordered to confiscate $1.5 million in property. Prosecutors said Nguyen, who ran an unlicensed money transfer business called National Vending from September 2017 to October 2020, used various techniques he learned in an online course to evade supervision. Nguyen learned how to conceal his true business from banks, cryptocurrency exchanges and state regulators, such as pretending to be a vending machine company that accepts cash deposits, fabricating fictitious supplier lists, and avoiding the use of the word "Bitcoin" whenever possible.
