The Debate Over Crypto Crime Statistics

Binance recently asserted that illicit trading on major cryptocurrency exchanges is nearly negligible. However, Chainalysis, whose data Binance cited, contends that this conclusion is not supported when the full spectrum of activity is considered.

This dispute highlights a deeper issue: crypto crime is not solely a technical challenge but also a narrative one, where definitions significantly impact the perceived extent of the problem.

Binance's Position: Minimal Criminal Inflows

In mid-November, Binance presented a breakdown arguing that illicit trading activity is exceptionally low. The exchange's calculation focused on transaction volumes across the seven largest exchanges, isolating wallets formally designated as illicit by regulators, and measuring direct inflows from these wallets to exchanges.

This specific calculation yielded figures between 0.018% and 0.023%. Based on this narrow scope, Binance concluded that criminal inflows are minimal and that the exchange itself has the lowest exposure among major platforms, implying that concerns about crypto crime are largely overstated.

Chainalysis's Rebuttal: The Methodological Discrepancy

Chainalysis acknowledges the accuracy of Binance's reported percentage but disputes what that percentage truly represents. The firm explains that criminals rarely send stolen or ransomware funds directly to large exchanges anymore. Instead, they typically move these funds through a series of smaller wallets to obscure their origin before they reach platforms like Binance or its competitors. Under Binance's methodology, these indirectly laundered funds are classified as non-illicit.

Chainalysis emphasizes that these indirect laundering routes are the dominant method in practice. The firm's data indicates that $2.2 billion in crypto was stolen last year, with $1.7 billion ultimately reaching exchanges, predominantly after being routed through intermediate wallets. Binance's metric, therefore, excludes this entire category of illicit activity.

TRM Labs's Agreement: Focusing on Direct Exposure

TRM Labs, another analytics firm mentioned in Binance's report, also issued a clarification. TRM Labs stated that the figures Binance used originated from a private dataset provided exclusively to the exchange, not from TRM's public reporting. Similar to Chainalysis, TRM stressed that the reported number reflected direct exposure only and could not be used to generalize about total illicit flows.

Both forensic firms concur that Binance did not misrepresent the number but rather chose the narrowest possible definition of illicit activity.

The Political Context of Compliance

This dispute arises at a critical juncture for Binance. Following a $4.3 billion penalty payment and navigating the sentencing and subsequent pardon of its former CEO, Changpeng Zhao, the exchange has been actively working to project an image of enhanced compliance and legitimacy.

The narrative surrounding crypto crime is significant. In an industry often assessed through headlines rather than thorough audits, the public and regulatory perception of "illicit activity" will influence policy directions and competitive dynamics for exchanges seeking legitimacy.

The Industry's Measurement Challenge

Crypto crime has not vanished, but the challenge of accurately measuring it persists. If regulators, analytics firms, and exchanges cannot agree on what constitutes illicit activity—whether it's the first wallet in a chain or the last—the debate over crypto crime will likely remain more about perspective than concrete numbers.

The disagreement between Binance and Chainalysis is not about the data itself but about the definitions used to interpret it.
