Tóm tắt

In a case involving a U merchant trading USDT (Tether) with transactions worth billions, the defendant was accused of illegal foreign exchange operations using virtual currency. Despite the large scale and use of multiple bank accounts, which authorities viewed as suspicious, the author argues that the defendant’s actions do not constitute crimes such as illegal business operations, concealing criminal proceeds, or assisting information network crimes. The article explains that OTC trading of virtual currencies like USDT is not illegal in China, and many platforms and individuals engage in it legally. The key is whether the trader knowingly facilitated illegal activities, such money laundering or illegal forex transactions. For illegal business operations, conviction requires proof that the defendant knowingly assisted in illegal forex exchanges, as in a cited case where the defendant helped convert foreign currency to RMB via USDT. For concealing criminal proceeds, the author emphasizes that the funds involved are often the principal amounts from transactions, not criminal profits, so merely handling these funds does not meet the legal definition. For assisting information network crimes, the crime must involve online illegal activities; if forex transactions occur offline despite online communication, it doesn’t qualify. The conclusion stresses the need for strict legal scrutiny and avoiding presumption of guilt based solely on transaction scale or methods.

Author: Lawyer Shao Shiwei

Recently, in a case involving the buying and selling of USDT (Tether) by a U merchant that Lawyer Shao is handling, the judicial authorities accused the client of engaging in illegal business activities involving the buying and selling of foreign exchange using virtual currency as a medium.

Although, in Lawyer Shao's view, the case has not yet formed a complete chain of evidence sufficient for conviction, due to the amount involved being as high as several billion, and the fact that in recent years the client used dozens of bank cards of relatives and friends for the collection and payment of virtual currency transactions, from the perspective of the case handlers, this operational model indeed does not resemble a "normal" business. Therefore, the prosecutor believes that even if it does not constitute the crime of illegal business operations, they are still considering charging the client with other crimes, such as the crime of obstructing credit card management, the crime of aiding information network criminal activities, the crime of concealing criminal proceeds, etc.

In <办案手记 | 买卖USDT借用他人的银行卡收款有什么风险?——从一宗数十亿虚拟货币案件看非法经营、帮信、掩隐罪等的认定边界与辩护要点> (Case Notes | What are the risks of using others' bank cards to receive payments when buying and selling USDT?—Looking at the boundaries of determination and defense points for the crimes of illegal business operations, aiding information network criminal activities, and concealing criminal proceeds from a virtual currency case involving billions), I have preliminarily sorted out the related issues. This article will further focus on practical controversies and systematically discuss the following core issues:

Why should buying and selling virtual currency to earn price differences not constitute the crime of illegal buying and selling of foreign exchange, the crime of aiding information network criminal activities, or the crime of concealing criminal proceeds?

1、The Logic of Presumption of Guilt from a Judicial Perspective: Is Buying and Selling Virtual Currency to Earn Price Differences an Abnormal Business?

From the perspective of case handling, the model of U merchants earning price differences typically has two characteristics:

First, using multiple bank cards for collection and payment; second, the huge volume of funds.

Compared with traditional businesses, this funding path is more likely to be presumed to have legal risks. Because of this, even if the crime of illegal business operations is difficult to substantiate, the case handling authorities often look for other "fallback charges."

But Lawyer Shao wants to emphasize that, according to domestic policies, buying and selling virtual currency (over-the-counter OTC) is not prohibited by law, and there is an objective fact that a large number of U merchants, arbitrageurs, and ordinary investors participate in OTC transactions in China.

Taking the Binance exchange as an example, opening the C2C section and selecting the conversion currency CNY (Renminbi) shows 1,300 merchants (10 per page, 130 pages)—this indicates that OTC U merchants are not an isolated phenomenon but a规模化 (large-scale) existence.

Furthermore, on the C2C sections of mainstream trading platforms such as OKX, Bybit, Bitget, MEXC, and Gate.io, U merchants普遍 (commonly)入驻 (enter) the transaction matching pages as compliant merchants.

It should be noted that platform merchants are just the tip of the iceberg. In practice, there are also a large number of purely offline matching U merchants who complete transactions through communities, acquaintance circles, or channels such as Telegram and WhatsApp. This part is also extremely large in volume.

From the types of cases in recent years, Lawyer Shao believes that the focus of judicial打击 (crackdown) is not "the act of buying and selling USDT itself," but three types of behaviors:

  • Continuing the transaction knowing that the funds received are involved in fraud;

  • Using virtual currency to help launder money;

  • Knowing that the upstream is engaged in disguised buying and selling of foreign exchange, still providing assistance.

Therefore, whether the model of OTC merchants earning price differences is "normal" should not be compared to traditional businesses. Instead, the perspective should be placed within the normal模式 (patterns) of the U merchant industry to compare whether the client's behavior is abnormal.

Otherwise, if one always views this industry and group with colored glasses simply because the model is unfamiliar, it carries the suspicion of "presumption of guilt."

Next, Lawyer Shao will systematically explain why this behavior does not constitute the crime of illegal business operations, nor does it constitute the crime of concealing criminal proceeds or the crime of aiding information network criminal activities.

2、Reasons for Not Constituting the Crime of Illegal Business Operations

The prerequisite for认定 (determining) that a person constitutes the crime of illegal business operations involving the buying and selling of foreign exchange using virtual currency is that there is evidence to prove that they subjectively knew that the upstream was engaged in "matching exchange" and still provided assistance for the upstream crime.

The case of Lin某 and Yan某 for illegal business operations published by the Supreme People's Procuratorate on December 21, 2024, is a typical case of this type:

  • From the perspective of the degree of subjective knowledge, Lin某, after being clearly informed by the Nigerian "Prince" of his intention to exchange currency, still provided assistance knowing the circumstances;

  • From the perspective of fund flow, Lin某 participated in the entire process where Prince used virtual currency as a medium to convert the local Nigerian legal currency, Naira, into Renminbi;

Therefore, Lin某's so-called "arbitrage" was essentially operating under the instructions of the Nigerian "Prince": Prince transferred Naira into Lin某's Binance account, Lin某 then sold the received USDT to domestic U merchants in exchange for Renminbi, and transferred the funds back to Prince. Lin某 determined the purchase price at 5% below the daily USDT listing price, then sold it to U merchants at the listing price, earning the price difference, thus constituting the crime of illegal business operations.

Therefore, U merchants a, b, and c, in such roles, would not constitute accomplices in Lin某's illegal business operation case simply because they had transactions with Lin某. Additionally, from the perspective of fund flow, another reason why U merchants a, b, and c in the above diagram do not constitute the crime of illegal business operations is that the transaction between the U merchants and Lin某 was limited to the one-way exchange between U and Renminbi, with the U merchants only earning the price difference profit. In contrast, the reason Lin某 constitutes the crime is that, although he was also earning a price difference profit, his transaction实际上 (actually) used virtual currency as a medium to achieve de facto exchange between different currencies for the Nigerian Prince, thus constituting the crime of illegal buying and selling of foreign exchange.

3、Reasons for Not Constituting the Crime of Concealing Criminal Proceeds

Is it possible to easily认定 (determine) that a U merchant is suspected of the crime of concealing criminal proceeds simply because the case involves huge fund transfers and multiple people's bank card receipts and payments?

Lawyer Shao believes that the determination of this crime cannot停留 (stop) at intuitive judgments such as "complex fund chain," "multi-card circulation," "large-value transactions," but must return to the core issue of the constitutive elements of criminal law: what is the criminal proceeds in the sense of criminal law?

According to the interpretation published on the official website of the Supreme People's Procuratorate[i], so-called criminal proceeds refer to the increase in property benefits obtained by the perpetrator through criminal acts and the maintenance of the part of their own property that should have been reduced. Simply put, criminal proceeds are the "profits" or "saved costs" generated by the crime, not the "principal" used for the crime.

Taking the typical underground currency exchange model as an example, the funds provided by the exchange customer are often Renminbi or foreign currency they originally obtained legally, but were used for illegal exchange行为 (behavior). This part of the funds is the principal for the exchanger; for the underground bank, it is not their criminal proceeds. The true "illegal gains" of the underground bank are usually only the exchange handling fees or exchange rate differences charged.

That is to say, the exchange principal itself does not automatically become "criminal proceeds" simply because it was used for illegal exchange. Only the benefits actually obtained by the underground bank for providing services may constitute criminal proceeds.

Looking at the role of U merchants based on this. The behavior of the vast majority of U merchants is essentially buying and selling USDT based on market prices to earn price difference profits. In this process, the funds received by U merchants are mainly the Renminbi or USDT principal paid by the counterparty, not the "already laundered criminal proceeds" of the underground bank.

In other words, U merchants are more involved in the circulation of the transaction principal, rather than helping to transfer, conceal, or realize the criminal proceeds of the underground bank.

This is also a point that is easily confused (confused) in many cases: case handlers often see "upstream crime + downstream receipt of money" and habitually think that the downstream is concealing criminal proceeds. But in fact, if the upstream funds themselves are not criminal proceeds, then even if the downstream participates in the circulation, it lacks the core object basis for the crime of concealing proceeds.

From judicial practice, the typical behaviors真正 targeted (truly targeted) by the crime of concealing proceeds are often helping to transfer fraud proceeds, splitting funds to evade supervision, layered laundering,代为提现 (cashing out on behalf of others), or converting criminal proceeds into "seemingly legal" assets.单纯的 (Simply) OTC transactions by U merchants, normal transaction matching, completing consideration exchange based on market prices, are essentially not (not) part of this "concealing criminal proceeds" behavior pattern.

Therefore, in most scenarios where USDT is simply bought and sold to earn price differences, if the U merchant:

  • Did not participate in the overall closed loop of the underground bank's currency exchange;

  • Did not knowingly help the underground bank transfer funds;

  • Only engaged in normal transaction matching based on market prices;

Then, even if there is illegal exchange behavior upstream, it is difficult to determine that the U merchant constitutes the crime of concealing criminal proceeds based solely on fund flow records.

4、Reasons for Not Constituting the Crime of Aiding Information Network Criminal Activities

The crime of aiding information network criminal activities is also a "high-frequency alternative charge" for case handling units in such cases. But according to the provisions of Paragraph 1, Article 287之二 (bis) of the Criminal Law, the prerequisite for the crime of aiding is "knowing that others are using the information network to commit crimes." Therefore, the prerequisite for applying this charge is: the upstream crime belongs to an information network crime.

Thus, whether the upstream of a U merchant belongs to an "information network crime" becomes the prerequisite for whether the U merchant themselves can be认定 (determined) as committing the crime of aiding.

What is an information network crime? The key issue is whether the core perpetrating act of the crime relies on the information network for implementation and completion.

Even if the buyer and seller of the exchange agree on the exchange rate and match funds through communication software, the settlement of Renminbi and foreign exchange funds is completely done offline through bank transfers or cash within China. At this time, the information network is only a communication tool, and the core of the crime (illegal foreign exchange买卖 buying and selling) is realized offline. Therefore, the criminal behavior in this model is not a network crime.

If the行为人 (actor) not only makes contact through communication software but also completes the collection and payment of funds (especially using domestic Renminbi accounts and foreign foreign currency accounts for "separate collection and payment") entirely through online banking and third-party payment platforms. At this time, the core link of the illegal business operation crime (payment and settlement) relies on the information network. This behavior may be认定 (determined) as "using the information network to commit a crime." If a person provides bank accounts to assist such online收款 (collection), it符合 (conforms to) the applicable scenario for the crime of aiding.

A typical case where using virtual currency as a medium for illegal foreign exchange was determined as the crime of aiding is the入库案例 (case entered into the database) published by the Supreme People's Court on June 18, 2025—The Case of Guo某zhao, Fan某pin for Illegal Business Operations, Zhan某xiang, Liang某zuan for Aiding Information Network Criminal Activities (Database Number: :2025-03-1-169-001. This case is also one of the typical cases of punishing foreign exchange-related crimes jointly released by the Supreme People's Procuratorate and the State Administration of Foreign Exchange in December 2023)

Basic Facts of the Case[ii]:

Guo某zhao, builder of the illegal exchange website.

Fan某pin, member of the illegal exchange group trading virtual currency.

Zhan某xiang, Liang某zuan, persons who provided virtual currency trading platform accounts and Renminbi bank accounts to Fan某pin.

From January 2018 to September 2021, Chen某guo (handled in a separate case), Guo某zhao, and others built websites such as "TW711 Platform" and "Rapid Platform," using the virtual currency Tether as a medium to provide customers with exchange services between foreign currency and Renminbi. After exchange customers placed orders in the top-up, payment on behalf, and other business sections of the aforementioned websites, they paid foreign currency to the overseas accounts designated by the websites. The websites used the aforementioned foreign currency to purchase Tether overseas, then Fan某pin sold it through illegal channels to obtain Renminbi, and then paid the corresponding amount of Renminbi to the domestic third-party payment platform accounts designated by the customers according to the agreed exchange rate, earning exchange rate differences and service fees从中 (from this). The aforementioned websites illegally exchanged over 220 million Renminbi. Among them, Fan某pin, by operating the virtual currency trading platform accounts and Renminbi bank accounts provided by Zhan某xiang, Liang某zuan, and others, received over 6 million Tether from Chen某guo, exchanging it for over 40 million Renminbi.

The reasons for the judgment in this典型案例 (typical case) were:

  • In this case, Chen某guo, Wang某, and others built illegal exchange websites, adopted the method of collecting New Taiwan Dollars through overseas accounts and paying Renminbi through domestic accounts to buy and sell foreign exchange for profit, constituting the crime of illegal business operations.

  • Guo某zhao, in the joint crime, was responsible for providing technical assistance and did not participate in specific business activities or share illegal gains; Fan某pin, in the criminal process, followed instructions to operate transactions. According to law, both should be determined as accomplices in the crime of illegal business operations.

  • Zhan某xiang and Liang某zuan had a general knowledge that others were using the information network to commit crimes and provided bank accounts to defendant Fan某pin and others, thus they were convicted of the crime of aiding.

From this case, it can be seen that under the premise that the upstream was sentenced for the crime of illegal business operations, the reason Zhan某xiang and Liang某zuan were determined to have committed the crime of aiding in this case was: the method of illegal exchange upstream was carried out by building illegal exchange websites, and the core link of the illegal business operation crime relied on the information network.

Therefore, if although the actors also communicate online through communication tools (such as WeChat, Telegram, and WhatsApp), the information network is actually only a communication tool, and the illegal buying and selling of foreign exchange is realized offline, then the upstream crime does not constitute an "information network crime." Therefore, in this situation, the prerequisite for determining the downstream U merchants receiving funds as committing the crime of aiding is lost.

Additionally, judicial organs often use the fact that the actor's bank card was frozen, restricted from counter services, etc., during the process of buying and selling virtual currency as a reason to consider that the actor meets the subjective "knowing" requirement for the crime of aiding. But according to the following judicial interpretation, it can be seen that only upon receiving "funds involved in fraud"等 (etc.) can it be determined as "knowing" in the crime of aiding. This article actually regulates actors who provide assistance to电信网络诈骗 (telecommunications network fraud). But as mentioned earlier, in the crime of illegal business operations involving foreign exchange, the reason U merchants are implicated is that they unknowingly received the exchange funds from the customers of the upstream underground bank (usually the legal income source of the exchanger), which is not the "funds involved in fraud" mentioned in the following judicial interpretation.

Opinions of the Supreme People's Court, the Supreme People's Procuratorate, and the Ministry of Public Security on Issues Concerning the Handling of Criminal Cases such as Aiding Information Network Criminal Activities

5. Accurately Determining the "Knowing" in the Crime of Aiding Information Network Criminal Activities......

(2) After being subjected to measures such as restriction or suspension of services by financial institutions, telecommunications business operators, or internet service providers due to involvement in fraud and other abnormal circumstances,仍然实施有关行为的 (still carrying out the relevant behaviors);

5、Final Words

In cases involving virtual currency, the determination of guilt or innocence should still return to the examination of the evidence chain and the constitutive elements themselves. As emphasized in the discussion by the Shanghai No. 2 Intermediate People's Court, "In the absence of virtual currency legislation and insufficient financial supervision in China, we should结合 (combine) China's national conditions and the spirit of relevant policies, use presumptions cautiously, and strictly control the scope of determining knowledge[iii]." Therefore, for behaviors such as buying and selling USDT to earn price differences, and acting as a collection and payment agent,定性 (qualification) should be done prudently, avoiding inferring subjectivity from the outcome.

Câu hỏi Liên quan

QWhy does the author argue that buying and selling USDT for profit should not constitute the crime of illegal business operations related to foreign exchange?

AThe author argues that the key to convicting someone of illegal business operations using virtual currency for foreign exchange is evidence of subjective knowledge that the upstream party is engaged in 'matching foreign exchange' and providing assistance to such criminal activities. In the typical case cited (Lin's case), the defendant was directly instructed by a foreign national to facilitate the conversion of foreign currency to RMB via USDT, thus constituting the crime. However, ordinary U.S. merchants (U商) who merely engage in one-way conversion between USDT and RMB to earn a price difference, without participating in the complete foreign exchange process for upstream criminals, do not meet the criteria for this crime.

QAccording to the article, under what circumstances is the crime of concealing criminal proceeds not applicable to U.S. merchants trading USDT?

AThe crime of concealing criminal proceeds requires the funds involved to be 'criminal proceeds'—profits gained or costs avoided through criminal activity, not the principal used in the crime. For U.S. merchants, the funds they receive are typically the principal (RMB or USDT) from trading counterparts, not the criminal profits of upstream money laundering operations. If the U.S. merchant is only participating in the flow of transaction principal, earning a price difference through normal market transactions, and is not involved in helping to transfer, hide, or launder the criminal proceeds of upstream crimes, they do not constitute this crime.

QWhat is the prerequisite for applying the crime of assisting information network criminal activities to U.S. merchants, as discussed in the article?

AThe prerequisite for applying the crime of assisting information network criminal activities is that the upstream crime must be an 'information network crime,' meaning the core criminal act is implemented and completed relying on information networks. If the upstream illegal foreign exchange activities are primarily conducted offline (e.g., bank transfers or cash), with information networks merely serving as communication tools, it does not qualify as an information network crime. Thus, U.S. merchants receiving funds in such scenarios cannot be convicted of this crime, as the necessary precondition is absent.

QWhat are the three types of behaviors that the author identifies as the key focus of judicial crackdowns in recent cases involving virtual currency?

AThe three types of behaviors are: 1) Knowingly continuing transactions after receiving funds involved in fraud; 2) Using virtual currency to assist in money laundering; 3) Knowingly providing assistance to upstream parties engaged in disguised foreign exchange trading.

QHow does the article distinguish between 'criminal proceeds' and 'principal used in a crime' in the context of the crime of concealing criminal proceeds?

AThe article clarifies that 'criminal proceeds' refer to the increase in property benefits obtained through criminal acts or the avoidance of a decrease in one's own property (i.e., profits or cost savings from the crime). In contrast, the 'principal used in a crime' is the original funds (often legally obtained) that are utilized to commit the crime, such as the money a client uses for illegal foreign exchange. The principal itself does not become 'criminal proceeds' simply because it is used in an illegal act; only the actual benefits gained by the criminal (e.g., fees or exchange rate differences) qualify as criminal proceeds.

Bitcoin đang ở mức giá được nhiều nhà giao dịch coi là quan trọng cả về tâm lý lẫn kỹ thuật. Theo phân tích của chuyên gia weslad trên TradingView vào ngày 20/6, BTCUSDT đã chạm vào một vùng cầu mới có thể quyết định đợt biến động lớn sắp tới. Miễn là Bitcoin giữ được vùng hỗ trợ hiện tại, khả năng phục hồi lên vùng cung quanh 81.000 USD vẫn cao. Tuy nhiên, cảnh báo cũng rất rõ ràng. Mức 60.000 USD được xem là "ranh giới" cho phe mua. Nếu Bitcoin đóng cửa quyết định dưới ngưỡng này, triển vọng tăng giá sẽ bị vô hiệu hóa và mở đường cho một đợt sụt giảm sâu hơn. Sự thất bại ở một mức hỗ trợ được nhiều người theo dõi có thể kích hoạt dừng lỗ và thay đổi tâm lý thị trường. Trường hợp phục hồi lên 81.000 USD vẫn cần sự xác nhận. Phe mua cần bảo vệ thành công 60.000 USD, vượt qua các mức kháng cự lân cận và chứng minh nhu cầu đủ mạnh để đảo ngược xu hướng. Hiện tại, tình hình được xem như một bài kiểm tra hỗ trợ nhị phân: giữ vững thì kịch bản phục hồi còn, mất quyết định thì thị trường sẽ hướng tới một đợt điều chỉnh sâu hơn.

Góc Bất Khả Thi Thực Ra Là Một Vấn Đề Giả

Tác giả Billy Gao cho rằng khái niệm "tam giác bất khả thi" (decentralization - scalability - security) trong blockchain thực chất là một vấn đề giả. Bài viết chỉ ra rằng, mặc dù ngành công nghiệp tiền mã hóa đã xây dựng được hệ thống mật mã hùng mạnh nhất lịch sử, nhưng nó lại thất bại trong việc bảo vệ quyền riêng tư tài chính cơ bản của người dùng. Mọi giao dịch và số dư đều bị công khai theo mặc định. Bản chất thực sự của blockchain là một máy tính chia sẻ, chậm và đắt đỏ, nhưng không ai sở hữu. Ưu điểm duy nhất của nó là tính không cần cấp phép và khả năng chống kiểm duyệt. Tuy nhiên, đây cũng là nguồn gốc của hai khiếm khuyết chính ngăn cản dòng vốn lớn: (1) Vấn đề pháp lý từ tính mở và (2) Sự thiếu hụt quyền riêng tư. Tính minh bạch trên chuỗi không phải là lợi ích mà là một loại "thuế". Nó cho phép các hành vi như MEV và front-running, khiến người dùng thông thường bị mất giá trị. Các tổ chức tài chính lớn sẽ không bao giờ để toàn bộ sổ sách của họ bị công khai như vậy. Tác giả lập luận rằng quyền riêng tư và tuân thủ không đối lập nhau. Bằng các kỹ thuật mật mã tiên tiến như zero-knowledge proof, người dùng có thể chứng minh tính hợp lệ của một giao dịch (như đã qua KYC, trong giới hạn rủi ro) mà không cần tiết lộ mọi chi tiết nhạy cảm. Điều này cho phép kiểm toán và giám sát trong khi vẫn bảo vệ dữ liệu cá nhân. Giải pháp "quyền riêng tư mặc định + có thể chứng minh sự tuân thủ" được xem như một bản nâng cấp thuần túy cho blockchain hiện tại. Nó khắc phục hai khiếm khuyết cốt lõi, mở ra cánh cửa cho hàng nghìn tỷ USD từ các tổ chức tài chính chính thống và người dùng phổ thông – những người đòi hỏi cả tính bảo mật lẫn quyền riêng tư. Chỉ khi blockchain học được cách "giữ bí mật", tiềm năng thực sự của nó mới được giải phóng.

Tác giả chỉ ra rằng ngành công nghiệp blockchain đã dành một thập kỷ tập trung giải quyết "tam nan" (khả năng mở rộng, phi tập trung, bảo mật), nhưng lại bỏ qua hai trở ngại thực sự ngăn dòng vốn lớn: tính hợp pháp và sự riêng tư. Blockchain, bản chất là một máy tính chung chậm và đắt đỏ, phù hợp nhất cho tài sản kỹ thuật số thuần túy như tiền. Tuy nhiên, tính minh bạch mặc định của nó khiến mọi giao dịch và vị thế bị công khai, tạo ra một "thuế" dưới dạng MEV và front-running, xói mòn lợi nhuận của người dùng. Điều này là rào cản không thể chấp nhận đối với các tổ chức tài chính lớn. Trong khi vấn đề hợp pháp đang dần được giải quyết thông qua khung pháp lý, thì thiếu sót về quyền riêng tư vẫn tồn tại. Tác giả lập luận rằng quyền riêng tư (ẩn danh giao dịch) và tuân thủ (chứng minh dự trữ, KYC) không mâu thuẫn nhờ vào mật mã học hiện đại như bằng chứng không tiết lộ thông tin. Công nghệ này cho phép xác minh một tuyên bố (ví dụ: tài sản > nợ, đã qua KYC) mà không tiết lộ dữ liệu cơ bản. Việc tích hợp quyền riêng tư có thể chứng minh được với khả năng tuân thủ là một bản nâng cấp thuần túy cho blockchain hiện tại. Nó giữ nguyên các đảm bảo về sự đồng thuận phi tập trung trong khi loại bỏ "lỗ rò" thông tin, từ đó mở ra cánh cửa cho dòng vốn tỷ đô từ các tổ chức và cá nhân mong muốn bảo vệ hoạt động tài chính của mình. Hệ thống mật mã mạnh mẽ nhất từ trước đến nay cuối cùng cũng học được cách giữ bí mật.
