Privacy coins, crypto mixers, and money launderers: bitter pills in crypto mass adoption?

This text discusses a case where hackers made over $2 million by mining Monero through illicit activities. The article explores why Monero might have been an attractive choice for hackers, as it is easier to mine than some other cryptocurrencies and can be exchanged relatively easily for fiat currency. However, the text also emphasizes that privacy coins like Monero have legitimate use cases and were developed to improve the functionality of the crypto industry.


Let’s explore the complex issue of privacy in cryptocurrencies by delving into the effects of anonymity techniques such as coin mixers and privacy tokens on the widespread acceptance of crypto, against the backdrop of increasing financial misconduct.

As a crypto investor looking back, I can tell you that on January 3, 2009, something revolutionary happened in the world of finance. That was the day when anonymity took center stage, giving birth to what we now call cryptocurrencies.

Originally, creators of cryptocurrencies believed they could prevent economic collapse by offering an alternative to traditional fiat currencies. Today, however, regulatory bodies face ongoing challenges as criminals exploit the system, stealing vast sums of money each year.

As a financial analyst, I’ve heard the concern that criminals, including money launderers, may prefer to use cryptocurrencies for illicit activities due to their perceived anonymity. This notion has cast a shadow over the crypto world. However, it is essential to delve deeper into this issue and understand its true implications. Let’s explore the extent of this association between cryptocurrencies and money laundering.

Crypto mixers and privacy coins: anonymizing transactions

Let’s clarify something important before discussing the influence of crypto mixers and privacy coins on the cryptocurrency scene: although transactions are recorded on digital ledgers, cryptocurrencies offer more pseudonymity than anonymity. In simpler terms, the identity of the sender or receiver is concealed, but the fact that a transaction took place remains visible.

In summary, cryptocurrencies aren’t completely anonymous as some transactions can be traced. In response, certain crypto developers have proposed solutions for fully concealing transactions. Two popular methods are crypto mixing services and privacy coins.

Crypto mixers, also known as tumblers, serve as intermediaries that blend together funds from multiple sources, making it challenging to trace the origin of specific cryptocurrency coins. In contrast, privacy coins are digital currencies that incorporate advanced cryptographic techniques such as stealth addresses to heighten the confidentiality of their users’ transactions.

The primary function of privacy coins and crypto mixers makes them an attractive choice for financially deceitful individuals looking to conceal the trail of their transactions.

As a crypto investor, I’ve closely followed the latest report published by Chainalysis early in the year. The findings revealed an alarming figure: approximately $24.2 billion in cryptocurrencies were received by illicit addresses during the financial year 2023.

Delving more deeply into this topic, we can examine the incidents that give scammers confidence when they choose to engage in cryptocurrency activities.

Tornado Cash 

The European Union’s (EU) Innovation Hub for Internal Security has revealed that cybercriminals frequently use crypto mixing platforms such as Tornado Cash to conceal the origin of ill-gotten funds and escape detection. As reported by the EU hub, these services significantly hinder regulatory efforts in promoting widespread acceptance of cryptocurrencies.

As a research analyst at the EU Innovation Hub, I’m excited to announce the release of our latest findings on the role of encrypted communications in criminal investigations. Our report underlines the importance of striking a balance between security and privacy in this context.

Based on the information provided,

It’s uncertain what the hacker intends to achieve with the cryptocurrencies transferred to the mixers. Regrettably, occurrences like these have significantly impacted Alexey Pertsev, one of Tornado Cash’s co-founders, who was given a sixty-four month sentence for money laundering by a Dutch court in May.

As a crypto investor, I’ve come across the term “crypto mixers” like Tornado Cash, which were designed to enhance the anonymity aspect of virtual currency transactions. However, I’ve learned that these services have unfortunately been exploited by illicit actors such as money launderers and scammers. Consequently, some open-source software creators have had to reconsider their development or improvement of similar functionalities due to the potential legal risks associated with them.

Tornado.Cash: Nobody has ever owned or managed it. On Ethereum, an unownable, perpetual, non-custodial open-source application can be written and deployed, which operates independently. This is cutting-edge technology that warrants new regulations. Imprisoning individuals for coding is morally wrong.

The crypto community is strongly supporting Tornado Cash’s co-founder, as advocated by privacy champion Chris Blec for new regulations to protect user privacy in evolving blockchain tech. However, potential harm may have already occurred.

Privacy coin Monero, money laundering, and CSAM watch

As a crypto investor, I can’t deny the allure of privacy coins like Monero (XMR). They represent an intriguing advancement in our digital currency world. We all value the benefits they offer, such as confidentiality and discretion – essential aspects that resonate deeply with cryptocurrency users.

Regrettably for the community, those two entities – music producers and cryptocurrency exchanges – are prime targets for music money laundering, hacking, and scam artists. Consequently, they capitalize on the features and benefits of utilizing privacy coins.

CSAM cases

In Chainalysis’ latest cryptocurrency crime analysis, it was revealed that Monero was extensively utilized by purveyors of child sexual abuse material (CSAM) during the fiscal year 2023. According to the data from Chainalysis, Monero plays a more substantial role in facilitating CSAM vendors’ money laundering activities off-chain compared to just hiding their transactions.

Chainalysis shared a snapshot of a CSAM-affiliated dark web forum asking for donations in Monero.

As a researcher studying the cryptocurrency market, I’ve come across the notion that vendors prefer Monero over other cryptos due to its compatibility with instant exchanges. Instant exchanges function without keeping users’ funds in their possession and typically avoid crypto-to-fiat conversions. However, it is essential to note that these platforms are centrally managed by a single organization, unlike decentralized finance protocols.

These platforms facilitate trading by drawing from various exchanges to provide competitive prices and enable direct crypto-to-crypto transfers between users’ wallets. As a result, on-chain transactions can become difficult to track. Additionally, these exchanges generally have less stringent KYC regulations, making them attractive for concealing the source of cryptocurrency transactions.

Scamming gamers

In 2021, cybercriminals exploited the gaming community by installing the malware named “crackanosh” on widely-played games. This malicious software enabled global computer power to be harnessed for cryptocurrency mining without the users’ knowledge.

Due to their robust processing capabilities, gaming computers have been an alluring target for hackers. They generated approximately $2 million in illegitimate profits, specifically Monero, through exploiting these powerful machines.

Privacy coins, crypto mixers, and money launderers: bitter pills in crypto mass adoption?

As a researcher, I’ve come across an intriguing question: why do some individuals opt for Monero mining over other cryptocurrencies like Bitcoin? One possible explanation is that Monero offers a more accessible mining experience compared to the complex and resource-intensive process of Bitcoin mining. Another theory could be that Monero provides a relatively straightforward method to convert the mined digital currency into fiat money, potentially allowing for seamless integration into everyday life.

The stories may give the impression that Monero causes more harm than benefit, which is far from the truth. Cryptocurrencies with privacy features were created to expand the capabilities and applications of the crypto sector. However, their names have been sullied by fraudsters and money launderers, resulting in increased scrutiny from financial and regulatory authorities.

Improving crypto’s reputation: what we can do

More recently, at a gathering hosted by the Hong Kong Polytechnic University, the head of cryptocurrency data analysis firm Bitrace, Isabel SHI, shared her perspectives on crypto-related criminal activities.

Isabel SHI, the CEO of Bitrace, was extended an invitation to Hong Kong Polytechnic University for delivering a talk entitled “The Role of Cryptocurrencies in Crime and Money Laundering.” During her presentation, she delved into the reasons behind the prevalent use of cryptocurrencies in illicit activities, while also introducing novel forms of criminal behavior that have emerged as a result.

Isabel initiated her discussion by examining the prevalent employment of cryptocurrencies in illicit activities and highlighted three key features making them ideal for such purposes: anonymity, which keeps transactions clandestine; decentralization, ensuring no central authority can regulate or trace the exchanges; and ease of cross-border transfers, enabling swift and unimpeded money laundering operations.

The CEO highlighted that cryptocurrency transactions conducted through on-chain addresses don’t require Real Know Your Customer (RKYC) verification, making it challenging to trace these transactions back to specific individuals. Additionally, she emphasized the unique feature of cryptocurrencies where only those holding private keys have the authority to manage their digital assets.

As an analyst, I’d like to add that the characteristic traits of cryptocurrencies – permissionless and borderless – make them alluring for criminal activities due to their ability to facilitate global transactions around the clock.

Based on Bitrace and Isabel’s observation, it appears that fraudulent activities can originate from weaknesses within blockchain systems. To mitigate these issues and discourage money launderers and scammers, while simultaneously allowing crypto mixers and privacy coins to prosper without negative connotations, we could implement specific measures.

Crypto mixers and privacy coin developers have a crucial role in preventing misuse of their services by money launderers, hackers, and scammers, thereby promoting the widespread acceptance of cryptocurrencies. To achieve this goal, they can consider implementing the following measures:

Crypto mixers

  • Developers should implement strict KYC verification processes to authenticate users and deter anonymous transactions.
  • Companies can collaborate with regulatory authorities and comply with anti-money laundering (AML) and counter-terrorism financing (CTF) regulations.
  • Integrating blockchain analytics tools can help crypto mixers and the community monitor transactions for suspicious patterns and intervene promptly.
  • Since not many users know how to use tumblers responsibly, companies should educate them on the consequences of illicit activities to promote ethical behavior.

Privacy coins

  • Developers can conduct regular audits and publicly disclose development activities to build trust with regulators and stakeholders.
  • Collaborating with law enforcement to share information on suspicious transactions and combat misuse effectively will bolster regulation.
  • Implementing optional auditability or compliance features to cater to users prioritizing regulatory compliance.
  • Educating the community about the benefits of privacy while emphasizing responsible usage will discourage illicit activities.

Privacy slows down adoption, but it’s still important

Cryptocurrencies have faced challenges in gaining widespread acceptance due to the employment of crypto mixers and privacy coins, yet their role in enhancing financial confidentiality is significant and should not be disregarded. These tools provide a desirable level of anonymity for certain users, but concerns regarding regulatory compliance and illicit activities linked to them have emerged.

Despite the need for developers to strengthen controls and collaborate with regulatory bodies, it remains possible for cryptocurrency adoption to reach a tipping point with the emergence of new technologies. However, necessary actions must be taken by developers in this regard.

Recognizing that privacy and regulatory compliance are not mutually exclusive, the future of cryptocurrencies can stay favorable for both authorities and crypto enthusiasts.
