Stablecoins Dominate Illicit Crypto Activities Eclipsing Bitcoin

Why Dollar Pegged Tokens Have Become the Preferred Tool for Criminals in 2025

In 2025 the landscape of illicit cryptocurrency activity shifted dramatically as stablecoins digital tokens pegged to fiat currencies overtook Bitcoin as the most used assets in illegal transactions. According to new data from Chainalysis shared with CryptoSlate, stablecoins accounted for roughly 84 percent of all identified illicit crypto transaction volume during the year, a clear reversal from previous years when Bitcoin’s volatility and liquidity made it the primary medium for such activity. This development reflects both the growing use of stablecoins as a bridge between traditional and digital finance and the unique risks they pose in criminal finance contexts.

Stablecoins are designed to maintain a steady value equal to a traditional currency such as the U.S. dollar. They have become ubiquitous in trading, payments, and decentralized finance because they allow users to avoid volatility and move value quickly without the price swings associated with tokens like Bitcoin or Ether. However, those same features price stability, ease of transfer, and wide availability across blockchains also make them attractive to actors seeking to move money quickly without losing value. Criminals have increasingly used stablecoins to facilitate money laundering, darknet market transactions, sanctions evasion, and other illicit activities precisely because they hold value reliably while being difficult to trace once moved through complex networks.

Bitcoin, once the go-to asset for illicit crypto flows due to its global reach and liquidity, has gradually ceded that role as criminals adapt their strategies to leverage more efficient tools. Chainalysis’s data shows that the sheer volume of suspicious stablecoin transactions has overtaken Bitcoin’s share of flagged activity, underscoring how criminal finance strategies evolve with market innovation. Analysts point out that stablecoins’ price stability reduces the risk of value loss during transfers, a factor that matters to illicit operators even more than blockchain transparency or decentralization.

This trend has prompted concern among regulators, law enforcement, and financial watchdogs. Organizations such as the Financial Action Task Force (FATF) have highlighted stablecoins as a growing risk vector in global financial crime, noting that clandestine activity involving stablecoins appears to be rising with their adoption across legitimate markets as well. Since stablecoins are often integrated deeply into trading infrastructure and payment systems, bad actors can exploit gaps in compliance and oversight to layer, move, and obscure criminal proceeds more readily than with more volatile tokens.
