Catenaa, Wednesday, June 03, 2026- Stablecoins have overtaken bitcoin as the preferred cryptocurrency for illicit transactions, marking a major shift in global crypto crime patterns as regulators intensify scrutiny of digital dollar networks.
Data cited by blockchain analytics firms showed bitcoin’s share of illicit crypto transaction volume fell from roughly 70% in 2020 to about 7% in 2025, while stablecoins surged to approximately 84% of illegal transaction flows.
The findings were highlighted by bitcoin-focused financial services firm River, which argued that the long-standing narrative portraying bitcoin as the primary tool for crypto crime is rapidly becoming outdated.
Stablecoins such as Tether’s USDT increasingly dominate scams, sanctions evasion and fraud-related activity because of their stable dollar-pegged value.
Unlike bitcoin, stablecoins maintain relatively fixed values tied to fiat currencies, making them more practical for criminal networks seeking predictable transaction pricing.
Blockchain researchers said scams and financial fraud operations particularly favor stablecoins because the assets avoid the volatility associated with bitcoin and other cryptocurrencies.
Sanctioned entities meanwhile increasingly use stablecoins for cross-border transactions and settlement operations.
Bitcoin still remains commonly used in ransomware payments and darknet marketplaces due to established infrastructure and anonymity tools developed around the asset over many years.
Chainalysis and TRM Labs data showed stablecoins accounted for roughly 63% of illicit onchain transactions during 2024 before rising further in 2025.
The shift could reshape global regulatory priorities as authorities increasingly focus on stablecoin issuers and digital dollar compliance systems.
Analysts said regulators are likely to demand stricter oversight, wallet-freezing capabilities and transaction monitoring frameworks from stablecoin providers.
The trend may also weaken one of the most persistent criticisms directed at bitcoin, which has historically been associated with criminal financing narratives.
Meanwhile, stablecoin issuers face growing pressure to strengthen anti-money laundering controls and cooperate more closely with law enforcement agencies.
Tether and other issuers already work with investigators to freeze wallets connected to illicit activity.
River argued the data reflects changing criminal preferences rather than expanding anonymity within crypto markets.
Blockchain analytics firms noted that stablecoins now dominate many forms of crypto-enabled fraud because of their settlement stability and broad liquidity access.
Researchers added that stablecoin monitoring systems remain highly traceable despite the rise in illegal usage.
Stablecoins have grown into one of the largest sectors of the digital asset industry, with total circulating supply recently surpassing $300 billion globally.
The assets increasingly support remittances, decentralized finance, cross-border payments and institutional settlement systems.
At the same time, governments worldwide continue developing stablecoin regulations amid concerns surrounding financial stability, sanctions enforcement and illicit finance risks.
