Defense practice using culpability stratification and amount limitation as its approach.
Recently,Attorney Deng Xiaoyu, a partner at Mankun (Shenzhen) Law Firm,achieved a satisfactory defense outcome in a case involvinga gold merchant in the Shenzhen Shuibei market charged with concealing and disguising the proceeds of crime.In this case, although the amount involved reached several million yuan, the client signed a sentencing recommendation for a suspended sentence during the review and prosecution stage.

The case arose from a gold merchant in the Shenzhen Shuibei market who received gold in transactions and, through a USDT dealer, liquidated the gold and converted it into virtual currency (USDT), and who was unwittingly drawn into a cross-border money laundering case (concealing and disguising the proceeds of crime). Investigation established that part of the funds was confirmed to be proceeds of telecom and online fraud. The case-handling authorities therefore opened an investigation against the merchant and related persons.
After Attorney Deng Xiaoyu's teamtook over the case, a thorough review of the case file revealed a key difference in the fund flow: the funds at issue were not directly converted into the crypto asset USDT, but were first used incash formto purchase gold, after which the client completed the transaction through USDT. On this basis, the team argued that the core money laundering link occurred inthe upstream "cash gold purchase"stage, the party's transactional conduct was at theend of the chain, precisely definingthe party's role as an accessory in the transaction chain.
On this basis, Attorney Deng Xiaoyu's team further conducted a detailed review of the amount involved in the case. By verifying the flow of funds transaction by transaction, the team successfully established thatof the several million in gold sheet material involved in the case, the amount verified and defended as proceeds of crime was less than one million, substantially lowering the sentencing benchmark. In light of the party's attitude of admitting guilt and accepting punishment, the team, focusing on"accessory status"and"amount segregation"as the core, engaged in professional communication with the procuratorial authority, and ultimately, in this case of concealing or disguising the proceeds of crime, at the review and prosecution stagesuccessfully obtained a sentencing recommendation of probation。
This case is a typical criminal risk casearising from oversights in transaction intermediation and fund-flow processes. As the complexity of combining gold transactions with virtual currencies increases, the legal risks faced by practitioners when handling large-sum funds have become increasingly prominent.
The successful defense in this case not only secured the optimal outcome for the client involved, but alsosounded a warning for gold merchants and virtual currency transaction practitioners: when conducting business, they should strictly perform due diligence and compliance obligations to prevent unknowingly becoming involved in criminal liability.
