On September 24, 2021, the central bank and ten other departments jointly issued the "Notice on Further Preventing and Dealing with the Risks of Virtual Currency Trading Speculation (hereinafter referred to as the "924 Notice")". Some of the views in this article will be elaborated in conjunction with the relevant spirit of the 924 Notice. Related At present, the suspected crimes in the currency circle have attracted more and more attention from the investigating authorities. As a link in the transaction of legal currency and digital currency, the currency circle OTC is more likely to be discovered in the entire criminal chain and is at the forefront of the entire case. Due to the limited understanding of the currency circle industry by the investigating authorities, OTC merchants often know nothing about the law. The resulting information gap and cognitive gap have led to a large number of OTC merchants being "accidentally injured". Therefore, in the defense of suspected crimes of aiding and abetting letters in the currency circle OTC, it is necessary to focus on the legality of the OTC behavior and whether the suspect has the subjective intent to commit a crime to defend innocence. At the same time, for those who do constitute a crime, based on the consideration that aiding and abetting crimes are minor crimes, they should be combined with specific criminal circumstances, social harm, etc. to defend the crime of minor crimes, and strive for non-prosecution and the use of suspended sentences. At the same time, criminal reverse business such as disposal of non-involved property and rights protection also runs through the defense work.

1. Although the behavior of OTC in the cryptocurrency circle is an illegal financial activity, it is not equivalent to a crime

The OTC behavior in the cryptocurrency circle is usually referred to as "over-the-counter transactions" in the circle. Its essence is the exchange of legal currency and digital currency. In a nutshell, it is the exchange of money with one hand and currency with the other. Because of the customary term "over-the-counter transactions", there are many misunderstandings among the law enforcement agencies. Many law enforcement officers do not understand the cryptocurrency industry and relevant laws, regulations and departmental rules. When they hear the word "over-the-counter", they have a preconceived idea that OTC behavior is illegal and improper. Therefore, it is necessary to clarify relevant legal and regulatory issues.

First, normal individual OTC behavior can only be considered as illegal financial activities at most. In previous relevant documents, negative evaluations were made on institutional OTC behavior, and individuals were not explicitly prohibited from engaging in transactions between legal tender and virtual digital currency. According to the 924 Notice, "illegal financial activities such as legal tender and virtual currency exchange business... are strictly prohibited and resolutely banned in accordance with the law. Those who engage in related illegal financial activities that constitute a crime shall be investigated for criminal responsibility in accordance with the law." In the notice, no subject was added before the relevant statement. From a cautious perspective, it should be regarded as an individual engaging in OTC behavior that is identified as an illegal financial activity, but at the same time, the notice also states that "if a crime is constituted, criminal responsibility shall be investigated in accordance with the law." In other words, normal and general individual OTC behavior should at most be evaluated on general illegality. As a departmental regulation, the 924 Notice can only serve as a prerequisite for constituting a crime, but cannot be the basis for determining a crime. It also needs to be examined based on all subjective and objective factors.

Second, individual OTC should not use "off-site" and "on-site" as the standard to evaluate the nature of behavior. The so-called "on-site transaction" is the transaction between individuals and trading platforms, while "off-site transaction" is the transaction between individuals separated from the trading platform. It should be made clear that there is no "on-site transaction" in my country at present! Before the 94 announcement, individuals and trading platforms could engage in legal currency transactions. For example, if a buyer wants to buy virtual digital currency, he only needs to pay the legal digital Huobi to the platform, and the trading platform will pay the corresponding virtual digital currency to the buyer. This is an on-site transaction. The 94 announcement completely prohibits this behavior, but does not prohibit legal currency transactions between individuals. Therefore, after the 94 announcement, trading platforms can no longer engage in legal currency transactions with individuals. At present, the trading platform widely adopts the matching mechanism. For example, if a buyer wants to buy virtual digital currency, the platform will "introduce" all sellers who want to sell virtual digital currency to the buyer. The buyer transfers the legal currency to the seller offline through a bank or WeChat or Alipay. After receiving the money, the online seller confirms with the trading platform. After confirmation, the trading platform will put the seller's virtual digital currency into the buyer's "wallet", and a legal currency transaction ends here. In summary, from an offline perspective, the buyer gives the seller a legal currency, and from an online perspective, the seller gives the buyer a virtual digital currency. During the entire process, the trading platform does not participate in the transaction and does not charge any handling fees. In essence, the trading platform is not involved. Even if it is matched by the trading platform, it is still an over-the-counter transaction in essence, which is no different from the "one hand over money, the other hand over currency" between individuals. Therefore, when determining whether an individual's OTC behavior constitutes a crime, especially when it constitutes "knowingly" subjectively, it should not be distinguished by "over-the-counter" or "on-site", but should be comprehensively determined based on the transaction price, transaction volume, KYC review, chat records and other relevant circumstances.

Third, whether individuals engaging in legal currency transactions fall within the scope of the 924 Notice still needs further explanation from relevant departments. Previous documents all stated that "virtual currency is a specific virtual commodity", and the 924 Notice did not deny this. However, according to the requirements of the 924 Notice, individuals cannot engage in legal currency transactions or currency-to-currency transactions. Therefore, the most compliant approach for existing virtual digital currencies is to hoard them, which is obviously inconsistent with the previous positioning of virtual digital currencies as specific virtual commodities. Therefore, does the complete prohibition of personal legal currency transactions violate higher-level laws or administrative regulations? At the same time, the 924 Notice mentioned "conducting legal currency and virtual currency exchange business, and exchange business between virtual currencies". Do currency-to-currency transactions and legal currency transactions between general virtual digital currency enthusiasts belong to engaging in a "business"? In particular, can currency-to-currency transactions between players be considered as civil acts of barter? It still needs to be explained by relevant departments or relevant judicial precedents.

2. The innocence defense strategy for the cryptocurrency OTC suspected of aiding and abetting crime

The Criminal Law Amendment (IX) adds the crime of assisting information network criminal activities, that is, knowing that others use information networks to commit crimes, providing Internet access, server hosting, network storage, communication transmission and other technical support for their crimes, or providing advertising promotion, payment settlement and other assistance, which is an independent crime. In the criminal law community, the crime of assisting is considered to be the principal crime of the accessory. The author believes that in the defense practice, the suspected crime of assisting in the crime of the coin circle OTC mainly involves the assistance of "payment settlement". The focus of the defense of innocence for the crime of assisting in the crime is mainly on whether it is "knowingly", that is, whether the criminal suspect has the subjective intention to commit the crime. For the case handling agency, its preconceived presumption of guilt will lead to the confession of some suspects being inconsistent with the actual situation, or the confession of the suspect who thinks "nothing" under the induced situation, such as "I roughly know that the source of these money is improper", which can actually be determined to have subjective intention to commit a crime. Therefore, the defense counsel should defend the suspect's lack of criminal intent in combination with the following specific circumstances.

First, whether individual OTC merchants have fulfilled their KYC obligations. In the process of trading, individual OTC merchants should first clarify who the trading object is. It is not enough to know who it is. It is also necessary to determine whether the trading personnel and the bank card holder are the same. In the practice of the currency circle, video authentication is usually adopted, that is, the other party is required to record a video holding an ID card and a bank card. The content is usually "My name, ID card, and bank card are all mine. My source of funds is legal and legitimate, and I am willing to admit any legal responsibility." In this way, individual OTC merchants can determine the basic situation of the other party to the transaction with themselves. It should be considered that individual OTC merchants have fulfilled their prudent KYC obligations. After all, individual OTC merchants are just ordinary individuals. They do not have many query systems of judicial organs and cannot further verify the counterparty. The defense believes that if individual OTC merchants have fulfilled their KYC obligations and can provide relevant information of the other party during the investigation by the case-handling agency, it should be determined that they do not have subjective criminal intent.

Second, whether the transaction price obviously violates the market conditions. Many investigating agencies believe that individual OTC merchants often have slightly higher transaction prices than the market conditions during transactions, and therefore believe that individual OTC merchants have criminal intent, which also reflects that the investigating agencies do not have a deep enough understanding of the currency circle OTC. First of all, there are differences in the legal currency transaction prices of trading platforms. Taking the legal currency transaction price in Huobi app as an example when the author wrote this article, the lowest price of USDT was RMB 6.58 and the highest price was RMB 6.61, with a difference of RMB 0.03. With the gradual deepening of the crackdown on "two cards" by public security organs, the situation of frozen cards for legal currency transactions in the currency circle has become more and more serious. Mainstream trading platforms such as Huobi app have launched the so-called "Blue Shield Merchants", that is, merchants with high KYC certification and good reputation. The prices of such merchants will also be more expensive, even RMB 0.05 more expensive than the prices of normal platform users. Therefore, the defense believes that as long as the transaction price does not obviously violate the market conditions, the criminal suspect cannot be determined to have subjective intent by the transaction price being higher than the market price. The vast majority of individual OTC merchants are mainly engaged in the "reverse U" business, that is, they buy USDT with RMB at a price slightly lower than the trading platform, and then sell USDT at a price slightly higher than the trading platform. This process is called "reverse U", and the actual profit is the difference of a few cents between the purchase and the sale. The author has represented some currency circle OTCs suspected of aiding and abetting crimes, covering up and concealing the proceeds of crime. The transaction price of some OTC merchants is a few cents higher than the market price or even more. In this case, if the OTC merchant argues that he does not know that the other party's source of funds is illegal, this defense is difficult to be accepted by the court. After all, a normal OTC merchant should know the market situation, and a normal transaction counterparty cannot "send money" for no reason.

Many investigators believe that since buying and selling can be matched on the trading platform, why do we need to find OTC merchants over the counter? They believe that OTC merchants have criminal intent. In fact, to a large extent, this is also a helpless move in the currency circle. The author has also participated in digital currency transactions. At present, the phenomenon of frozen cards in legal currency transactions, especially in the process of exchanging digital currencies for RMB, is very common. Some people have calculated that the freezing rate is over 30%, which is a very exaggerated number. Therefore, for the sake of safety, the two parties to the transaction will not be easily frozen. They can only seek more familiar and reliable OTC merchants to trade over the counter. Even if the prices of these OTC merchants are slightly higher than those of the trading platform, they can only make this choice for safety. After all, if there are cheap and reliable merchants, who will choose more expensive ones? Therefore, if the transaction price does not seriously violate the market conditions, it cannot be determined that the individual OTC merchant has subjective criminal intent because the transaction price has a slight deviation from the market conditions.

Third, whether the other party's transfer bank card has been subject to necessary review. Taking the sale of USDT as an example, as an individual OTC merchant, in addition to the transaction price, the most important thing to care about is whether the source of the other party's money is legal, and whether the transaction behavior will cause their own card to be frozen. Therefore, the vast majority of individual OTC merchants are most afraid of receiving black money. At present, the common trading practice in the industry is to require the other party to provide bank transaction flow. If the transaction flow is less than one month, the transaction will usually not continue. Only the transaction flow is not enough. The other party needs to use the bank card to transfer money to their own WeChat, and then use WeChat to withdraw money to the bank card to prove that this card is a "live card". At the same time, it is necessary to determine whether there is any abnormality in the other party's WeChat account. Only when the above-mentioned transaction risks are eliminated, individual OTC merchants dare to continue legal currency transactions. If the suspect has performed all the above-mentioned tasks, how can it be determined that he has the subjective intention to receive black money? How can it be considered that he subjectively has the behavior of providing payment settlement for criminal acts.

Fourth, the size of the transaction amount has nothing to do with whether there is subjective criminal intent. Many investigators believe that the transaction amount of individual OTC merchants is too large and there is subjective criminal intent. The basic logic is that individual OTC merchants conduct such large transactions without asking about the source of funds, which does not conform to objective logic. In fact, the currency circle is a relatively closed circle, and there are many players who hold huge virtual currency assets, and there are also many "million-coin marquises". You must know that the value of 10,000 bitcoins is about 3 billion yuan. Buying mining machines, paying electricity bills, and paying employees wages all require a large amount of virtual digital currency to be converted into RMB. Large transactions are widely present in the currency circle OTC, so the size of the transaction amount cannot be used as one of the factors to determine that the suspect has subjective criminal intent.

3. Defense ideas for the lighter crime of the cryptocurrency OTC suspected of aiding and abetting crime

Since aiding and abetting crimes is a minor crime with a sentence of less than three years, in most cases, a defense of a minor crime is also a good choice. For example, the defense counsel believes that the basic evidence proving the suspect's suspected crime is relatively comprehensive through the composition of the personnel subject to compulsory measures, the situation of items seized on the scene, and the collection of electronic evidence. In this case, blindly making a not guilty defense will lead to a more severe punishment of the suspect. In this case, when meeting with the suspect, the relevant laws and regulations should be explained clearly. In addition to the aiding and abetting crime itself, the relevant content of the procedural law should be explained, so that the suspect can find a better "way out" based on his actual situation. Most people in the currency circle have a weak legal awareness. Some suspects behave very extreme, blindly resist investigations, do not confess truthfully, and miss the opportunity to be released on bail and not approve arrest. In this case, they are often sentenced to actual imprisonment in the later stage. For cases where there is indeed evidence to prove suspected crimes, the defense attorney should make detailed record of the meeting during the meeting that can prove that the criminal suspect has an attitude of admitting guilt and accepting punishment, to prevent the investigating agency from failing to express the criminal suspect's subjective attitude well in the record. In addition, the defense attorney should determine the amount of illegal gains with the criminal suspect and actively return it. Submitting the above materials together when the case is reported for approval of arrest can often obtain a non-arrest result of "no need for arrest."

IV. Disposal of non-involved property suspected of crimes in the cryptocurrency OTC industry and other matters

On December 5, 2020, at a seminar on criminal issues in the field of Internet finance, the author introduced relevant cases about the currency circle and judged that the efforts of the case-handling agencies to crack down on criminal crimes in the currency circle will become stronger and stronger, and the efforts to recover and confiscate the digital currencies involved will also become stronger and stronger. On January 25, 2021, the Supreme People's Procuratorate of China held a press conference on "Giving Full Play to the Procuratorial Function to Promote Cyberspace Governance". Zheng Xinjian, director of the Fourth Procuratorate of the Supreme People's Procuratorate, said at the meeting that "the formation of an ecosystem for cyber black and gray industries has continuously "transfused blood and provided food" for cyber crimes, becoming an important reason for the high incidence of cyber crimes. In combating and governing cyber black and gray industries, the procuratorate first highlights the focus of punishment and cuts off the chain of interests. Second, it strengthens the application of property penalties, increases the cost of crime, prevents criminals from gaining benefits from crime, and achieves "cutting off the money and blood". Third, it combines the performance of procuratorial duties to promote comprehensive governance." Among them, the issue of the application of property penalties was highlighted. And "cutting off the money and blood" is very easy to be used as a sword by local case-handling agencies to detain, freeze, and confiscate the legal property of the persons involved in the case beyond reasonable limits. Prior to this, many criminal judgments in the cryptocurrency industry also showed that the criminal suspects and defense counsel’s defense that some of the property involved in the case was legal property did not receive support from the court. For example, in the Plustoken case, which has a wide impact in the cryptocurrency industry, the Criminal Ruling No. (2020) Su09 Criminal Final 488 shows that the Intermediate People’s Court of Yancheng City, Jiangsu Province, held: “The issue of Chen Bo’s legal property identification. Upon investigation, Chen Bo did not provide any relevant clues or materials that he legally owned more than 700 bitcoins. In addition, the Plustoken platform was identified as a pyramid scheme platform, and the digital currency invested in the platform was used for the capital operation of the pyramid scheme system, and should be confiscated as property used for pyramid scheme crimes.”

In the cases related to the cryptocurrency industry that I have represented, it is not uncommon for individuals’ legal property to be over-frozen and seized. This has also put forward newer and higher requirements for the defense lawyers, namely how to safeguard the legal rights and interests of criminal suspects, and how to prevent individuals’ legal property from being investigated, seized, frozen, or even confiscated. This is also a new area of ​​legal services for criminal cases, summarized as “criminal reverse business”. This legal service demand is particularly important in the cryptocurrency industry. The reason is that some law enforcement agencies handle cryptocurrency cases with tinted glasses, and they preconceived that as long as it is a cryptocurrency case, there is no legal property. Even if the suspect can prove that it is legal property, it is still “a fine and done”.

When handling relevant cases, I will collect a lot of evidence for the legal property of the suspects to form a complete chain to prove that the relevant digital currency is the legal property of individuals. For example, some suspects earn digital currency through transactions. In this case, they can retrieve all transaction records on the exchange by sending emails to the exchange, and systematically describe the transaction process in legal language and submit it to the case-handling agency. Some suspects make huge profits by investing in the primary market, which requires actively contacting the project party, issuing relevant supporting materials, and retrieving chat records, investment contracts, and transfer records on the chain to prove it. Other suspects obtain digital currency by investing in mining machines. They need to retrieve mining machine purchase contracts, mining machine operation and maintenance contracts, mining machine maintenance records, electricity bill payment records, and digital currency output records, etc., supplemented by relevant chat records and other content to prove the generation process of digital currency in legal assets.

In practice, even if all the above evidence can be obtained and submitted to the investigating authorities, it is still difficult to unblock it in time, and there is still a risk of being fined and confiscated. Therefore, it is also necessary to prove that the digital currency in the individual’s legal assets has no relationship with the suspected criminal offense, that is, the individual’s legal property has not been used to fund criminal activities. In the process of argumentation, it is also necessary to analyze it in combination with the specific charges and different circumstances of the case. Due to limited space, I will not go into details here.

5. Conclusion Cases of suspected aiding and abetting crimes in the cryptocurrency OTC are quite common. Since aiding and abetting crimes themselves are minor crimes, many criminal suspects have given up looking for professional lawyers to defend them. Based on the characteristics of such crimes, the author believes that we must first understand through interviews whether the criminal suspects have subjective criminal intent and objective criminal behavior, and on this basis accurately choose the direction of defense of innocence and defense of lesser crimes. We cannot blindly use defense of lesser crimes to make the parties who should not be convicted of crimes bear a lifetime criminal record, nor can we blindly use defense of innocence to close the two doors of not approving arrest and discretionary non-prosecution to the parties.
