Exploring Money Laundering in Cryptocurrency

What Is Cryptocurrency?

Cryptocurrency refers to digital or virtual money which uses cryptography i.e. advanced encryption techniques, that enables secured transactions. Simply put, it’s a digital currency that allows people to make payments directly to each other through a secure network known as a blockchain. Generally, currencies such as pounds, euros, dollars, exist in your bank account but cryptocurrency exists purely in digital form i.e. no hard cash, it’s not physical money that you can hold in your hands. Although the money in your bank account is already in digital form, cryptocurrency possess a distinct feature that operates independently of central banks and governments.

When it comes to money laundering, it is the process of obscuring the source of illegally obtained money by making it appear as though it emanated from a legitimate source. This allows criminals (individuals and groups) to enjoy the proceeds of crime stemming from drug trafficking, corruption, fraud, tax evasion and financing of terrorism without attracting the attention of law enforcement agencies or regulatory authorities. The aim of criminals who engage in money laundering is to transform "dirty" money into "clean" money that can be spent legitimately.

Traditionally, in order to launder money, criminals use conventional banking systems, shell companies, trade-based schemes and cash-intensive businesses. Laundromats, restaurants, casinos, and retail stores are popular fronts for money laundering. Offshore accounts in jurisdictions that possess strong banking secrecy laws provide a better avenue for hiding the real owners of the assets. However, increased regulatory oversight with high-end systems for monitoring transactions alongside international cooperation, have made traditional money laundering riskier and more challenging for criminals to achieve.

Criminals looking for how to move large sums of money quickly across borders with reduced risk of detection, use cryptocurrency as a viable option instead of the usual traditional financial systems. The crypto space provides a pseudo-anonymous nature of blockchain transactions, wherein all transactions are recorded on a public ledger, making the wallet addresses not immediately apparent. Again, speed is of the essence for criminals and cryptocurrency possesses this as funds can be moved globally within minutes instead of days, and its decentralized structure means that there is no institution that controls the network or can freeze funds. Besides, regulatory gaps exist in some jurisdictions who offer minimal oversight of activities of these digital assets.

How Criminals Exploit Cryptocurrency

Pseudo-Anonymity

The vulnerability of the pseudo-anonymity feature of cryptocurrency is easily exploited by money launderers. They are aware that blockchain technology creates a permanent transparent record of all transactions and that these public ledgers do not inherently reveal names of people as they are pseudonymous (linked to wallet addresses, which act as aliases). Therefore, a person can generate various addresses at no cost making it hard to link different addresses to such a person. For instance, a criminal might receive illicit funds in one wallet, then split these funds across 40 or more different addresses within minutes, with a view to creating a complex web that investigators can’t unravel. Unlike traditional bank accounts that require verification of identity, cryptocurrency wallets can be created anonymously and used immediately to provide entry points for dirty money without the know-your-customer scrutiny procedures (depending on whether it’s de-centralized or centralized exchanges).

Fast Cross-border Transactions

Cross-border transactions in cryptocurrency happens very fast. For example, a money launderer in Dubai can send Bitcoin to an accomplice in the UK who then forwards it to another associate in Southeast Asia, within one hour. These transactions will bypass all the traditional banking systems, corresponding banking relationships and associated checkpoints for compliance. In cryptocurrency, there are no business hours, no waiting for international clearing systems and intermediary banks who might flag suspicious activities. This borderless nature makes jurisdiction-specific regulations problematic to enforce and allows criminals to move funds through countries with weaker anti-money laundering controls.

Decentralized Exchanges

Decentralized exchanges and mixing services have become essential vehicles for money laundering. Centralized exchanges generally require verification of identity but decentralized exchanges operate through smart contracts without a central authority controlling transactions. Users can swap one cryptocurrency for another directly from their wallets without creating accounts or providing identification. It’s also possible for a money launderer to convert stolen Ethereum into Bitcoin through a decentralized exchange, then use mixing services to complicate the trail. Mixing services also known as tumblers, pool together cryptocurrency from different users and redistribute them, thereby breaking the direct link between sending and receiving addresses. For instance, if someone sends one Bitcoin to a mixer, he/she receives one Bitcoin back but from a completely different source in the pool thereby making it nearly impossible to trace the original funds.

Privacy Coins

Privacy coins such as Monero (XMR) and Zcash (ZEC), were developed with enhanced anonymity features that go beyond Bitcoin's pseudo-anonymity. Monero uses ring signatures, stealth addresses and confidential transactions to hide the sender - receiver and transaction amounts from public view, thus making them harder to trace. Although these privacy features have legitimate uses for individuals concerned about their finances being under surveillance, money launderers have also found it to be very appealing. For instance, a criminal might convert Bitcoin obtained through ransomware attacks into Monero successfully creating a "black hole" where the transaction trail ends. Many exchanges have delisted privacy coins due to regulatory pressure but peer-to-peer platforms and decentralized exchanges continue to enable their trade.

Peer-to-Peer Trading Platforms

Peer-to-peer trading platforms, connect buyers and sellers directly without the platform taking custody of funds and in some cases performing meaningful verification. Some services allow users to trade cryptocurrency for cash, bank transfers, gift cards or other methods of payment. For instance, a money launderer might advertise on these platforms offering to buy Bitcoin with cash above-market rates rather than meeting the seller in person to exchange the proceeds from drugs for cryptocurrency. These platforms often have minimal or inconsistent compliance standards especially for lower-value transactions, thereby creating blind spots in the anti-money laundering drive. Some high-end operations use peer-to-peer platforms across different countries, and at the same time break transactions to avoid raising any red flag.

Detection Methods

Transactions that are void of economic rationale or deviate from how the user generally behaves, calls for immediate scrutiny. For example, when a newly created account immediately receives a transfer of large cryptocurrency and then quickly sends those funds across dozens of addresses within hours, this behavior suggests activities of layering as opposed to the normal usage. The fast movement of funds across different wallets is evident of the layering stage in money laundering.

Transactions involving high-risk exchanges or jurisdictions can trigger enhanced due diligence procedures. For instance, certain exchanges have developed reputation for having lax standards in compliance, minimal verification of identity and operational jurisdictions that have weak anti-money laundering frameworks. Where an analysis of a transaction reveals that funds being sent to or received from exchanges in countries known for financial secrecy or those that have been identified by the Financial Action Task Force as having strategic deficiencies, such should be treated as elevated risk. For example, if a customer regularly sends cryptocurrency to an exchange in a jurisdiction with no regulatory framework for digital assets and then quickly withdraws approved currency to local banks, this pattern shows potential layering and integration of illicit funds.

The Global Regulator

The global regulatory framework for cryptocurrency when it comes to anti-money laundering is anchored by the Financial Action Task Force, an intergovernmental organization that sets international standards for fighting money laundering and financing of terrorism. The FATF has issued specific guidance for virtual assets and virtual asset service providers treating cryptocurrency exchanges, wallet providers and certain decentralized finance platforms for regulatory purposes. A major development is the "Travel Rule," which requires cryptocurrency businesses to collect and share information of the customer for transactions above certain thresholds. FATF recommendations are not legally binding, but member countries are expected to implement them through domestic legislation so as to create a framework that enhances cooperation world-wide.

In conclusion, the potential of blockchain technology and digital assets cannot be fully realized if they become a haven for money laundering and other financial crimes. Exchanges, wallet providers, and blockchain analytics firms must continue to develop and implement high-end compliance tools. Compliance professionals must also be abreast of new regulations, keep tabs of techniques used in laundering money and swiftly deploy relevant compliance tools to stop the illegal activity.
