Ningbo Customs Anti-Smuggling Bureau has cracked a series of smuggling cases involving virtual currency mining machines, seizing over 400 "mining machines."

According to Zhejiang Daily, recently, the Ningbo Customs Anti-Smuggling Bureau successfully dismantled multiple criminal gangs smuggling virtual currency "mining machines" through in-depth operations and meticulous investigations, effectively cutting off an illegal industrial chain.Previously, during a routine inspection of a batch of imported express shipments declared as "industrial blockers," Ningbo Customs discovered that the actual goods did not match the declaration and were, in fact, virtual currency "mining machines." Customs officers quickly transferred this lead to the anti-smuggling department. After receiving the report, the Ningbo Customs Anti-Smuggling Bureau immediately assembled a task force by drawing on elite personnel, and through data analysis and clue investigation, gradually clarified the organizational structure and operational model of the criminal network. When the timing was right, they decisively struck, simultaneously conducting net-seizing operations in Dongguan, Shenzhen, and other locations, successfully dismantling multiple smuggling gangs of mining machines.Upon investigation, it was confirmed that this series of cases seized over 400 illegal entry mining machines of brands such as Ant L9 and Ice River KS3. The investigation revealed that the smuggling gang led by Liao, in order to make illegal profits, procured "mining machines" from overseas suppliers, disassembled the whole machines, and misreported the product names to smuggle them into the country through international express channels from ports in Ningbo, Guangzhou, and other places. After the goods entered the country, the gang reassembled them, either selling them directly domestically or transporting them to hidden "mining sites" in Xinjiang, Hunan, and other places to engage in illegal virtual currency "mining" activities. At the same time, they utilized virtual currencies like USDT for cross-border payment settlements to evade financial supervision.

Binance Research: The seizure rate of illegal funds in crypto assets is about 11% in 2025, significantly higher than that of the traditional financial system

Binance Research released a report stating that crypto assets are not a "safe haven for illegal funds." In 2025, approximately 11% of illegal fund flows in the global crypto sector have been seized or frozen, which is about 55 times the recovery rate of traditional fiat currency systems.The report pointed out that this data is derived from public law enforcement and freezing actions by institutions such as Tether, Interpol, and T3 Financial Crime Unit, rather than statistics from a single regulatory agency. At the same time, compared to the United Nations Office on Drugs and Crime (UNODC) estimated recovery rate of less than 1% for illegal funds in the traditional financial system, the tracking and recovery efficiency in the crypto sector is significantly higher.The research also mentioned that even after excluding a single large case (involving about $15 billion in Bitcoin related to the Prince Group), the remaining crypto asset recovery rate in 2025 is still about 10 times that of the traditional financial system. Additionally, data from SlowMist and PeckShield shows that in 2025, approximately 8.3% to 13.2% of stolen crypto assets were successfully recovered or frozen, reflecting improved efficiency in security response and collaboration among exchanges, stablecoin issuers, and law enforcement agencies.The report concluded that while the issue of crypto crime still exists, the view that "crypto assets are inherently more suitable for illegal activities" is being weakened by on-chain transparency and regulatory collaboration capabilities.

On-chain analysis questions the U.S. accusations of "Iranian cryptocurrency assets," with some seized wallets possibly related to actors from other countries

According to Cointelegraph, Nominis analysis indicates that some of the "Iran-related" crypto wallets recently seized and frozen by the U.S. OFAC may not exhibit on-chain behavior characteristics consistent with the past operational patterns of the Islamic Revolutionary Guard Corps (IRGC), suggesting the involvement of other state-level actors.Previously, the U.S. Treasury stated that over $340 million, totaling nearly $500 million in Iran-related crypto assets, had been frozen in the "Operation Economic Fury." Nominis CEO Snir Levi noted that historically, IRGC-related wallets typically spread funds across multiple addresses, maintain low balances in single wallets, avoid long-term holdings, and employ complex operations to reduce the risk of being frozen; however, the wallets that were seized this time show significant differences in their funding structure and behavior patterns.He believes this raises a critical question: how much of the frozen $340 million in assets is directly controlled by the IRGC, and how much involves broader infrastructures that may even overlap with financial networks of other countries.Levi also pointed out that organizations, including the IRGC and potential state-level actors from China, are continuously upgrading their use of blockchain infrastructure, and traditional static risk control labels are no longer sufficient; behavioral analysis and address clustering are becoming increasingly critical.
