The importance of Crypto Exchanges for Bitcoin Money Laundering by Chainalysis

LONDON (Fintech Zoom)  – Bitcoin Money Laundering – This article is an excerpt from the Chainalysis 2020 Crypto Crime Report

Once a criminal has a pile of illicitly-gained cryptocurrency (Bitcoin scams) sitting in a wallet, the next question they have to answer is, “How am I going to turn this into cash without getting arrested?” The need to launder funds is the common thread among all the forms of crypto crime we analyze.

So, how do criminals do it? Thanks to the inherent transparency of blockchains, we can look at cryptocurrency’s money laundering ecosystem from a high level, and draw insights that aren’t possible when studying money laundering in the traditional fiat currency world. Let’s start by examining the most common destinations to which criminals have sent Bitcoin over time.

 

Please note: Risky services include P2P exchanges, mixing services, high risk exchanges, and gambling sites. Illicit services include ransomware addresses, sanctioned entities, darknet markets, and addresses associated with scams and stolen funds.

While exchanges have always been a popular off-ramp for illicit cryptocurrency, they’ve taken in a steadily growing share since the beginning of 2019. Over the course of the entire year, we traced $2.8 billion in Bitcoin that moved from criminal entities to exchanges.  Just over 50% went to the top two: Binance and Huobi.

Binance and Huobi lead all exchanges in illicit Bitcoin received by a significant margin. That may come as a surprise given that Binance and Huobi are two of the largest exchanges operating, and are subject to KYC regulations. How can they be receiving so much Bitcoin from criminal sources? Let’s start by looking at the specific accounts receiving illicit funds at both exchanges.

Overall, just over 300,000 individual accounts at Binance and Huobi received Bitcoin from criminal sources in 2019. Who’s behind those accounts? Are any of them significant traders? Below, we’ve broken those accounts down into buckets based on the total value of all Bitcoin they’ve received in 2019, with illicit Bitcoin called out (please note that due to the nature of how we connect illicit funds to specific addresses, this chart considers only $1.1 billion of the total $1.4 billion worth of illicit Bitcoin received by Binance and Huobi).

How to read this graph:

  • The green bars represent the number of unique accounts in each bucket. Again, the buckets are based on the total amount of Bitcoin the accounts have received individually, from both criminal and non-criminal sources. All accounts shown have received at least some criminal funds.
  • The yellow and red stacked bars show the total amount of cryptocurrency received collectively by all the accounts in each bucket. That means, for example, that the 31 accounts in the highest-earning bucket on the right-hand side have collectively received just over $8 billion worth of Bitcoin in 2019, and that each of those 31 accounts individually has received between $100 million and $1 billion worth.
  • The red segment of the bars represents the amount of illicit Bitcoin received by all accounts in each bucket.
  • The yellow segment represents the non-criminal funds received by the accounts in each bucket.

We can see from this graph that a small segment of these accounts is extremely active. The 2,196 accounts in the three highest-receiving buckets received a total of nearly $27.8 billion worth of Bitcoin in 2019. The graph also makes it clear that Bitcoin from criminal sources represents just a small fraction of the total amount received by Binance and Huobi. Nonetheless, the illicit funds shown above comprise a significant total value — the 31 accounts in the top-earning bucket alone received a total of over $163 million worth of Bitcoin from criminal sources in 2019.

Let’s look at another version of this chart where we only include funds that have come from accounts we know are connected to illicit activity (i.e. those represented in red above).

A small segment of accounts took in most of the illicit Bitcoin sent to Binance and Huobi. The 810 accounts in the three highest-receiving buckets took in a total of over $819 million in Bitcoin from criminal sources, representing 75% of the total. Who are the whales driving this activity?

Our analysis suggests that many are OTC brokers.

OTC (Over The Counter) brokers facilitate trades between individual buyers and sellers who can’t or don’t want to transact on an open exchange. OTC brokers are typically associated with an exchange but operate independently. Traders often use OTC brokers if they want to liquidate a large amount of cryptocurrency for a set, negotiated price. OTC brokers are a crucial source of liquidity in the cryptocurrency market. While it’s impossible to know the exact size of the OTC market, we know that it’s huge. Cryptocurrency data provider Kaiko even estimates that OTCs could facilitate the majority of all cryptocurrency trade volume.

The problem, however, is that while most OTC brokers run a legitimate business, some of them specialize in providing money laundering services to criminals. OTC brokers typically have much lower KYC requirements than the exchanges they operate on. Many of them take advantage of this laxity and help criminals launder and cash out funds, usually first by exchanging Bitcoin and other cryptocurrencies into Tether as a stable intermediary currency before they presumably cash out into fiat.

From our analysis of transactions by various criminal groups, we put together a list of 100 major OTC brokers we believe provide money laundering services, based on the fact that they’ve received large amounts of cryptocurrency from illicit sources. This is not an exhaustive list of corrupt OTC brokers; rather it is a sample we assembled based on our experience investigating money laundering over time. We’ll call them the “Rogue 100.”

70 of the OTC brokers in the Rogue 100 are in the group of Huobi accounts receiving Bitcoin from illicit sources. 32 of them are in the group of 810 accounts receiving the most illicit Bitcoin, and 20 of them received $1 million or more worth of illicit Bitcoin in 2019. In total, these 70 OTC brokers received $194 million in Bitcoin from criminal entities over the course of 2019. Interestingly, none of those 70 Rogue 100 accounts operate on Binance, though it’s possible some of them also have accounts there or on other exchanges as well.

What can the cryptocurrency industry do about OTC brokers and money laundering?

The money laundering infrastructure driven by OTC brokers enables nearly every other type of crime we cover in our Crypto Crime Report. After all, if there were no way for bad actors to cash out cryptocurrency they’ve received through illegal means, there’d be far less incentive for them to commit crimes in the first place. That would mean not only fewer victims affected by crimes, but would also help improve cryptocurrency’s reputation as the industry seeks to work with regulators and traditional financial institutions and drive increased adoption.

Luckily, there are steps that law enforcement agencies, regulators, and cryptocurrency businesses can take to start stamping out money laundering. It all starts with transparency. Money laundering, especially in the fiat world, is typically thought of as a black box one can only open and begin to understand by getting a search warrant and poring over a suspect’s bank records. But with blockchain analysis tools like Chainalysis, we can analyze transactions recorded on the blockchain and get insight into how criminals are laundering funds much faster, as we show above. Law enforcement agents and regulators need to become experts in this technology in order to start fighting money laundering in cryptocurrency.

We also call on exchanges to carry out more extensive due diligence on OTC brokers and other nested services operating on their platform. Most large exchanges, including Huobi and Binance, are already collecting KYC information on customers, as they’re required to do by law in most jurisdictions. Our analysis shows that they need to extend that scrutiny to OTC desks consistently over time and ensure the OTC desks have effective KYC processes on their customers in order to do their part in the fight against money laundering.
