As globalization and digitalization continue to advance, the rapid growth of the cryptocurrency market presents new business opportunities while also posing significant challenges to global legal and regulatory frameworks. The increasing interaction between cryptocurrencies and fiat currencies has led to a rise in illicit activities such as money laundering and terrorism financing. Moreover, the complexity of blockchain technology, which is outside the traditional domain of law enforcement, makes it difficult to identify specific criminals. This poses significant challenges for law enforcement agencies in combating these illegal activities. Additionally, various incidents have shown that regulating cryptocurrencies not only requires local legal support but also necessitates international cooperation to tackle cross-border crimes, money laundering, terrorism financing, and other issues. That is why we believe international cooperation in law enforcement, combined with the use of blockchain data analysis technologies, is set to become a major trend in combating cryptocurrency crime.<h2 id="header-0">Cryptocurrency and Criminal Activities</h2>According to CoinMarketCap, the global market capitalization of cryptocurrencies has now exceeded $2 trillion. Cryptocurrencies are becoming increasingly popular due to their decentralized nature, anonymity, and cross-border transfer capabilities, providing many conveniences for users. However, these same features also make cryptocurrencies an attractive tool for money laundering, terrorism financing, and other illegal activities.Statistics from the S<a href="https://hacked.slowmist.io/" rel="noopener noreferrer nofollow">lowMist Blockchain Security Incident Database</a> indicate that since 2012, blockchain-related crimes have resulted in at least $33.4 billion in losses.<img src="https://miro.medium.com/v2/resize:fit:700/0*T84G_FcP0f6pClWb" />Cryptocurrencies can be used both for payments and investments, and their strong anonymity has led to a growing demand among transnational organized crime groups (such as those involved in ransomware and terrorism). In simple terms, cryptocurrencies significantly lower the operational costs for international criminal organizations, enabling them not only to leverage arbitrage opportunities to gain more funds but also to transfer large amounts of funds without raising suspicion. For instance, to circumvent regulatory measures implemented within the international banking system, some criminal organizations use online platforms that support anonymous donations to raise cryptocurrencies. Previously, Interpol revealed information about organized crime groups engaging in large-scale money laundering using cryptocurrencies. These cases highlight how the “virtual,” “anonymous,” “hard to trace,” and “cross-border” characteristics of cryptocurrencies make it difficult for any single country or region to regulate them effectively, presenting new challenges to law enforcement.<h2 id="header-1">International Cooperation in Law Enforcement to Combat Cryptocurrency Crime</h2>To address the law enforcement challenges posed by cryptocurrencies, we believe international cooperation is essential for effective regulation and enforcement. Law enforcement agencies from various countries need to work together to tackle the evolving methods and technologies of cryptocurrency crime, enabling precise action against criminal activities. Numerous successful cases of international cooperation in law enforcement in the cryptocurrency field have demonstrated the necessity and effectiveness of this trend:- August 20, 2024: In collaboration between China and Thailand, China’s Ministry of Public Security successfully extradited Zhang Moumou, a suspect in economic crimes, from Thailand. Zhang was involved in organizing and leading pyramid schemes, marking a significant development in China-Thailand law enforcement and judicial cooperation. The group linked to Zhang engaged in online pyramid schemes by issuing virtual digital currencies, involving over 100 billion yuan and affecting more than 10 million members.- May 2024: With the support of Eurojust and Europol, French police, in collaboration with authorities from Portugal, Germany, Italy, and Romania, arrested a suspect who used fraudulent means to cause losses of €700,000 to victims in Portugal. The suspect approached victims by expressing interest in acquiring commercial enterprises, gaining their trust, and convincing them to install cryptocurrency wallets, subsequently stealing their funds.- February 19, 2024: The notorious ransomware gang LockBit’s website was seized during a joint law enforcement operation involving the UK’s National Crime Agency, the FBI, Europol, and Interpol.- 2022 Operation “HAECHI III”: This enforcement operation seized illicit cryptocurrency proceeds worth $130 million, involving the participation of law enforcement units from 30 countries and regions, resulting in nearly 1,000 arrests of cybercriminals. Interpol also blocked nearly 2,800 bank and cryptocurrency accounts used for criminal purposes, including pig-butchering scams, investment fraud, online gambling, and cross-border money laundering.- DarkMarket, one of the largest dark web markets globally, primarily facilitated illegal transactions using Bitcoin and Monero. In January 2021, German police, in coordination with law enforcement agencies from the US, UK, Denmark, Switzerland, and 15 other countries, successfully shut down DarkMarket, arrested key suspects, and froze millions of dollars in virtual assets.These cases underscore the importance of international cooperation and targeted technological support. Regardless of where the illegal profits are located, international collaboration to recover assets and combat crime effectively reduces the risk of illegal activities involving cryptocurrencies.<h2 id="header-2">The Role of Blockchain Technology in Combating Cryptocurrency Crime</h2>In addition to international cooperation, the effective utilization of blockchain technology is crucial in combating cryptocurrency crime. Blockchain itself is a highly transparent and traceable distributed ledger, meaning that advanced analytical tools and machine learning algorithms can be employed to monitor transaction activities in real-time, identify abnormal transaction patterns, and effectively combat money laundering and other illicit transactions.For example, specialized blockchain companies can analyze vast amounts of data they possess to prevent, identify, and trace cryptocurrency-related money laundering crimes, making technology a vital aid in preventing cryptocurrency crime and conducting investigations. Furthermore, while on-chain transaction data is publicly transparent, its anonymity and decentralized nature make it challenging to directly associate on-chain behavior with specific individuals. This necessitates law enforcement agencies to possess the technical knowledge required to effectively identify and collect evidence, seize illicit proceeds, and this can only be achieved through professional on-chain tracking and investigation training. In this context, blockchain security and compliance solutions like SlowMist AML (https://aml.slowmist.com) play a critical role in detecting, analyzing, and preventing cryptocurrency-related crimes.<img src="https://miro.medium.com/v2/resize:fit:700/0*fMQBQ681dDloAbfr" /><h3 id="key-services">Key Services</h3>1.
