Federal data indicate that virtual currencies—for example cryptocurrencies—are increasingly being used in illegal activities, such as human and drug trafficking. The use of virtual currencies has added to the challenges federal law enforcement face when trying to prevent and discover these crimes.
In today’s WatchBlog post, we look at our recent reports about what the federal government is doing about this growing issue, and our recommendations to improve this response.
The increased use of virtual currencies and online marketplaces in trafficking
Drug and human traffickers use virtual currency and peer-to-peer mobile payments because transactions are somewhat anonymous, making detection more difficult. For example, virtual currencies are being used more often on platforms that could facilitate sex trafficking. Specifically, in a June 2021 report, we found that 15 of the 27 online commercial sex marketplaces that we examined accepted virtual currencies. Also, virtual currency ATMs—stand-alone machines that facilitate buying, selling, and exchange of virtual currencies—can be used for illegal activities such as laundering drug trafficking proceeds.
Online marketplaces are also increasingly being used for sex and illegal goods trafficking. These marketplaces are sometimes located on the “dark web,” a hidden part of the internet where users access sites using specialized software (e.g. Tor) to connect to buyers and sellers. The dark web can provide some anonymity and limit the risk of detection by law enforcement. In contrast, data from surface web platforms (e.g. Google, Bing) are available to the public and law enforcement.

How is the federal government combating the illicit use of virtual currencies?
Several federal agencies are tasked with investigating and prosecuting trafficking cases that involve online marketplaces and virtual currency. These include federal law enforcement entities inside the Department of Justice (DOJ), such as the Drug Enforcement Administration (DEA) and Federal Bureau of Investigations (FBI), as well as the Department of Homeland Security (DHS). Other agencies, including the Department of the Treasury (Treasury), support investigations of trafficking cases. Some of their recent actions and investigations included:
- In 2016, DHS’s Immigration and Customs Enforcement’s Homeland Security Investigations and the Secret Service identified and seized $1.2 million from a trafficker’s virtual currency wallet.
- In 2020, an investigation by Treasury’s Internal Revenue Service Cyber Crime Unit helped shut down Helix, a dark web platform that laundered money for drug traffickers.
- Treasury’s Financial Crimes Enforcement Network (FinCEN) issued guidance to help financial institutions detect trafficking activity that involved virtual currencies.
- Federal banking, securities, and derivatives regulators oversee financial institutions’ compliance with Bank Secrecy Act/Anti-Money Laundering (AML) requirements, including their reporting of suspicious activities, such as potential trafficking. Law enforcement agencies use these data to investigate potential criminal activity.
Because many virtual currency transactions are permanently recorded on public blockchains, DOJ and other law enforcement agencies use blockchain analytics tools to investigate illegal activity. As we discuss in our February 2022 report, these tools use machine-learning algorithms to analyze behavioral patterns, interpret information on public blockchain ledgers, and create large databases of transactions that help identify payments associated with specific virtual currency wallets.
However, criminals’ use of privacy technology that obscures the movement of funds across the blockchain and some market participants’ noncompliance with AML requirements can make it harder to track some illicit transactions.
To help improve government monitoring of virtual currency use in human and drug trafficking, we recommended in our December 2021 report that FinCEN and IRS review certain registration requirements for virtual currency exchanges and administrators that operate virtual currency ATMs. Based on that review, FinCEN and IRS should make any needed updates to these requirements to enhance their oversight. By reviewing and improving these requirements, FinCEN and IRS can better prioritize their resources on high-risk virtual currency ATM locations and help law enforcement better target their investigations.

As a seasoned expert in the realm of cryptocurrency, blockchain technology, and the intersection of virtual currencies with illegal activities, I bring a wealth of firsthand knowledge and in-depth expertise to shed light on the critical issues discussed in the article.
I have actively followed the developments in the cryptocurrency space, keeping abreast of technological advancements, regulatory changes, and their implications for law enforcement. My insights are not merely theoretical; they stem from a robust understanding of the practical challenges faced by authorities in combating illicit activities involving virtual currencies.
The article underscores the escalating use of virtual currencies in illegal activities, particularly human and drug trafficking. This is a well-documented phenomenon, and the evidence supporting these claims is abundant. A key point mentioned is the anonymity afforded by virtual currencies, making detection more challenging. I can elaborate on the cryptographic principles that underpin this anonymity, including the use of private and public keys in transactions, as well as the role of blockchain in recording these transactions.
The reference to online commercial sex marketplaces accepting virtual currencies aligns with the growing trend of such transactions migrating to the digital realm. I can delve into the mechanisms employed by traffickers to exploit these platforms while leveraging the relative anonymity provided by virtual currencies.
The article rightly acknowledges the role of federal agencies, such as the Department of Justice (DOJ), Drug Enforcement Administration (DEA), Federal Bureau of Investigations (FBI), Department of Homeland Security (DHS), and the Department of the Treasury, in addressing these challenges. Drawing on my expertise, I can provide detailed insights into the specific actions and investigations carried out by these agencies, emphasizing their collaborative efforts.
The mention of virtual currency ATMs being exploited for illegal activities, including the laundering of drug trafficking proceeds, underscores the need for regulatory scrutiny. I can elaborate on the functionalities of virtual currency ATMs, the associated risks, and the regulatory measures implemented by agencies like the Treasury and FinCEN.
The role of blockchain analytics tools employed by law enforcement agencies is a crucial aspect of combating illicit activities. I can explain how these tools leverage machine-learning algorithms to analyze behavioral patterns, interpret blockchain data, and create comprehensive databases for tracking illicit transactions.
Finally, the article highlights the need for regulatory reviews and updates to enhance oversight. I can elaborate on the specific recommendations made in the December 2021 report, emphasizing how FinCEN and the IRS can play a pivotal role in improving the monitoring of virtual currency use in trafficking.
In conclusion, my expertise in cryptocurrency and blockchain technology positions me well to dissect and expand upon the multifaceted challenges posed by the illicit use of virtual currencies in the context of human and drug trafficking, as well as the ongoing efforts by federal agencies to address these issues.
