Bitcoin News Today: U.S. Seizes $15B Bitcoin as $75B Illicit Crypto Lingers Out of Reach

Blockchain analytics firm Chainalysis Inc. has identified over $75 billion in cryptocurrency linked to illicit activity currently sitting on public blockchains, presenting a significant opportunity for coordinated asset seizures by global authorities. The firm's analysis, published in October 2025, breaks down the holdings into two categories: $15 billion in direct balances attributed to criminal entities and $60 billion in downstream wallets receiving at least 10% of their inflows from illicit sources. This figure represents a 359% increase since 2020, with Bitcoin dominating 75% of the value held by illicit actors, despite a decline in its share of total coin holdings.

The report highlights that stolen funds account for the largest portion of illicit balances, as hackers often retain assets while testing laundering methods or awaiting cash-out opportunities. Darknet market administrators and vendors control over $40 billion of the downstream pool, reflecting the decentralized wealth distribution within these platforms. Chainalysis cautions that some laundering hubs and cross-chain bridges may act as transit points, potentially understating their role in criminal ecosystems.

Bitcoin's dominance in illicit holdings contrasts with the growing use of stablecoins and privacy coins for short-term liquidity and anonymity. While Bitcoin remains the primary asset for long-term storage, stablecoins like USDT and USDC are increasingly used to facilitate rapid conversions and obfuscate trails. The shift is evident in the data: illicit Bitcoin balances have dropped in volume since 2020 but surged in value due to price appreciation, while stablecoin usage in criminal activity has grown significantly.

Centralized exchanges remain a critical off-ramp for illicit funds, with inflows averaging $14 billion annually since 2020. However, criminals are adopting more complex strategies to evade detection, including increased use of mixers, cross-chain bridges, and rapid turnover of exchange accounts. Direct transfers to exchanges have plummeted from 40% of illicit flows in 2021–2022 to 15% in Q2 2025, as operators diversify their methods. Stablecoins drain the fastest post-seizure (95% within 90 days), while Bitcoin lingers longest, with only 52% liquidated in the same period.

The U.S. Treasury has already seized an estimated $15–$20 billion in Bitcoin, according to Secretary Scott Bessent, setting a precedent for asset forfeiture. Chainalysis estimates its tools, including KYT and Reactor, have aided authorities in recovering $12.6 billion in illicit funds. However, challenges persist in scaling these efforts, as technical capacity, cross-border cooperation, and legal frameworks remain fragmented.

TRM Labs' 2025 Crypto Crime Report corroborates the scale of illicit activity, noting that $45 billion in illicit crypto volume in 2024 could rise to $75 billion with revised attribution methods. Sanctions violations (33% of illicit volume) and blocklisted funds (29%) dominate criminal flows, while scams and fraud account for 24%. The report also warns that stablecoins now constitute 63% of laundering activity, surpassing Bitcoin's 20% share.

Policy initiatives, such as the U.S. Strategic Bitcoin Reserve and Digital Assets Stockpile, underscore the potential for governments to leverage seized crypto for economic growth. Chainalysis CEO Jonathan Levin emphasized that such reserves could redefine asset forfeiture strategies, enabling reinvestment into recovery efforts and criminal network disruption. However, the feasibility of accessing the full $75 billion remains uncertain, as law enforcement must overcome technical hurdles and coordinate internationally.
