US Secret Service Amasses $400 Million in Seized Cryptocurrency from Online Scams
The United States Secret Service has quietly built one of the world’s largest caches of seized cryptocurrency, accumulating nearly $400 million in assets confiscated from online scams over the past decade. Much of this digital fortune is currently held in a single cold-storage wallet, positioning the agency as an unlikely heavyweight among the globe’s top crypto custodians.
Unraveling Crypto Fraud Through Advanced Investigations
The agency’s Global Investigative Operations Center (GIOC) has been at the forefront of dismantling numerous sophisticated fraud schemes that prey on unsuspecting victims with promises of lucrative crypto investments. Many of these scams begin with simple, enticing messages that direct individuals to polished, professional-looking crypto investment websites.
Jamie Lam, an investigative analyst with the Secret Service, recently explained during a training session in Bermuda how scammers employ psychological tricks to lure victims. “They’ll send you a photo of a really good-looking guy or girl. But it’s probably some old guy in Russia,” she said, highlighting the deceptive tactics used.
Typically, targeted individuals see small “early profits” credited to their accounts on these fraudulent platforms, encouraging further deposits. However, as the scammers vanish with their victims’ funds, recovering the stolen assets becomes a complex challenge.
Harnessing Blockchain Analysis and Cross-Border Coordination
Utilizing advanced blockchain tracing tools, domain record examinations, and by exploiting occasional operational slips from criminals such as misusing VPNs, the Secret Service analysts have successfully tracked illicit funds across various jurisdictions. These efforts have enabled the agency to recover millions in stolen cryptocurrency, turning crypto’s supposed anonymity from a criminal advantage into a vulnerability.
Kali Smith leads the Secret Service’s training initiative, which teaches law enforcement agencies worldwide how to identify and crack down on digital criminals. Her team has conducted workshops in over 60 countries, focusing especially on regions with lax regulatory oversight or lenient residency programs known to attract scam operations.
Smith noted that law enforcement personnel often express surprise after training sessions, realizing the extent of crypto crime in their own locales.
Case Highlights and Partnerships with Industry
One notable operation involved an Idaho teenager who was blackmailed with compromising images, with ransom payments being laundered via another coerced teenager acting as a money mule. Analysts followed nearly 6,000 transactions to an account linked to a Nigerian passport, leading to the arrest of a suspect by British police upon arrival in Guildford, England.
Cooperation with major cryptocurrency companies such as Coinbase and Tether has been crucial in freezing and reclaiming stolen assets. In a landmark seizure, the Secret Service recovered $225 million in USDT (Tether) related to romance and investment scams—a record in the agency’s history.
On June 20, 2025, the Secret Service announced the seizure of over $225 million worth of cryptocurrency from a sophisticated blockchain-based money laundering operation, marking the largest crypto seizure the agency has conducted to date.
The Broader Context: Rising Crypto Crime in 2025
According to CertiK’s latest security report, crypto investors lost more than $2.2 billion to hacks, scams, and breaches in the first half of 2025. Wallet breaches accounted for approximately $1.7 billion, while phishing scams caused over $410 million in losses.
High-profile hacks such as Bybit’s $1.5 billion breach in February and Cetus Protocol’s $225 million exploit in May have significantly inflated these figures. Ethereum remains the primary target of such attacks, suffering losses exceeding $1.6 billion across 175 separate incidents in the first half of the year.
The report emphasized the increasing sophistication of phishing and social engineering attacks, underscoring the importance of vigilance, including verifying links, avoiding suspicious sites, and employing hardware wallets for security.
Conclusion
The US Secret Service’s extensive efforts to seize and secure illicit crypto assets demonstrate both the promise and peril of cryptocurrency. While digital assets offer new avenues for innovation, they also present challenges for law enforcement grappling with transnational crime. Through coordinated investigations, global training, and partnerships with industry players, the Secret Service continues to lead in turning the tide against crypto-related fraud.
