Stablecoins just replaced Bitcoin for crime on the dark web – and the reason why is a $154 billion nightmare
The period of the hooded hacker hoarding Bitcoin in a dark web pockets is over.
In 2025, the heart of gravity in the illicit cryptocurrency financial system shifted decisively away from the volatility of the authentic cryptocurrency and towards a dense, dollar-linked shadow system.
According to new Chainalysis knowledge shared with CryptoSlate, stablecoins accounted for 84% of the $154 billion illicit transaction quantity final yr, marking a clear shift in danger towards programmable {dollars}.
This structural shift has enabled Chinese cash laundering networks to scale “laundering-as-a-service” operations whereas nation-states like North Korea, Russia, and Iran plugged into these similar rails to evade Western controls.
Why criminals ditched Bitcoin
The most placing development in the 2025 knowledge is the displacement of Bitcoin as the primary currency of crime. For over a decade, Bitcoin was synonymous with illicit on-line exercise, however its dominance has eroded steadily since 2020.
As proven in the illicit exercise chart under from 2020 to 2025, Bitcoin’s share of dirty flows has plummeted yr after yr, whereas stablecoins have surged to seize the overwhelming majority of the market.
This migration is not unintentional. It mirrors tendencies in the broader, reputable crypto financial system, the place stablecoins are more and more dominant resulting from their sensible advantages: straightforward cross-border transferability, decrease volatility than property like Bitcoin or Ethereum, and broader utility in decentralized finance (DeFi) purposes.
However, these similar options have made stablecoins the most well-liked automobile for subtle felony enterprises.
So, the shift away from Bitcoin represents a modernization of monetary crime.
By leveraging property pegged to the US greenback, felony actors successfully make the most of a shadow model of the conventional banking system, one which strikes at the pace of the web and operates exterior the fast attain of US regulators.
This “dollarization” of crime permits cartels and state actors to settle funds in a secure unit of account with out publicity to the wild value swings that characterize the remainder of the crypto market.
The geopolitical pivot
If the interval from 2009 to 2019 was the “Early Days” of rogue area of interest cybercriminals, and 2020 to 2024 was the period of “Professionalization,” 2025 marked the arrival of “Wave 3”: Large-scale nation-state exercise.
In this new part, geopolitics has moved on-chain. Governments are actually tapping into the professionalized service suppliers initially constructed for cybercriminals whereas concurrently standing up their very own bespoke infrastructure to evade sanctions at scale.
Russia, specifically, demonstrated the viability of state-backed digital property for sanctions evasion. Following laws launched in 2024 to facilitate such actions, the nation launched its ruble-backed A7A5 token in February 2025.
In lower than one yr, the token transacted over $93.3 billion, permitting Russian entities to bypass the world banking system and transfer worth throughout borders with out relying on SWIFT or Western correspondent banks.
Similarly, Iran’s proxy networks have continued to leverage the blockchain for illicit finance.
Confirmed wallets recognized in sanctions designations present that Iranian-aligned networks facilitated cash laundering, illicit oil gross sales, and the procurement of arms and commodities to the tune of greater than $2 billion.
Despite numerous army setbacks, Iran-aligned terrorist organizations, together with Lebanese Hezbollah, Hamas, and the Houthis, are using cryptocurrency at scales by no means earlier than noticed.
North Korea additionally recorded its most harmful yr so far. DPRK-linked hackers stole $2 billion in 2025, a determine pushed by devastating mega-hacks.
The most notable of those was the February Bybit exploit, which resulted in losses of practically $1.5 billion, marking the largest digital heist in cryptocurrency historical past.
Money laundering industrialization
This surge in quantity is supported by the emergence of Chinese money laundering networks (CMLNs) as a dominant power in the illicit on-chain ecosystem. These networks have dramatically expanded the diversification and professionalization of crypto crime.
Building on frameworks established by operations akin to Huione Guarantee, these networks have created full-service felony enterprises.
They supply specialised “laundering-as-a-service” capabilities, supporting a numerous shopper base that ranges from fraudsters and rip-off operators to North Korean state-backed hackers and terrorist financiers.
A key development recognized in 2025 is the rising reliance of each illicit actors and nation-states on infrastructure suppliers that provide a “full stack” of companies.
These suppliers, that are themselves seen on-chain, have developed from area of interest internet hosting resellers into built-in infrastructure platforms. They present area registration, bulletproof internet hosting, and different technical companies particularly designed to resist takedowns, abuse complaints, and sanctions enforcement.
By providing a resilient technical spine, these suppliers amplify the attain of malicious cyber exercise. They enable financially motivated criminals and state-aligned actors to take care of operations whilst legislation enforcement businesses try to dismantle their networks.
Convergence of digital and bodily threats
While the narrative of crypto crime usually focuses on digital theft and laundering, 2025 offered stark proof that on-chain exercise is more and more intersecting with violent crime in the bodily world.
Human trafficking operations have more and more leveraged cryptocurrency for monetary logistics, shifting proceeds throughout borders with relative anonymity.
Even extra disturbing is the reported rise in physical coercion attacks. Criminals are more and more using violence to force victims to switch property, usually timing these assaults to coincide with cryptocurrency value peaks to maximise the worth of the theft.
Illicit exercise stays lower than 1% of crypto financial system
Despite these alarming tendencies, the broader context stays vital. The illicit volumes tracked in 2025 stay lower than 1% of the reputable crypto financial system.
However, the qualitative shift in that 1% is what considerations regulators and intelligence businesses. The integration of nation-states into the illicit provide chain by way of stablecoins raises the stakes for nationwide safety.
As authorities businesses, compliance groups, and safety professionals look towards 2026, the problem might be disrupting a professionalized, state-sponsored shadow financial system that has efficiently weaponized the effectivity of recent finance.
Cooperation among law enforcement, regulatory our bodies, and crypto companies might be essential, as the integrity of the ecosystem now intersects instantly with world geopolitical stability.
