The U.S. Secret Service is reportedly expanding its cryptocurrency crime prevention efforts, according to a report focusing on the agency’s Global Investigative Operations Center (GIOC), which specializes in digital financial crimes. In the last decade, sources told Bloomberg, the center has seized close to $400 million in digital assets. Most of those seized funds, the report added, are in a single cold-storage wallet, making the Secret Service — better known for guarding the president — one of the largest crypto custodians in the world. According to the report, the operation is overseen by Kali Smith, a lawyer who directs the Secret Service’s cryptocurrency strategy, and whose team has held training workshops for law enforcement in more than 60 countries. The agency focuses on jurisdictions where criminals take advantage of a lack of oversight or residency-for-sale programs, and offers the training for free. “Sometimes after just a weeklong training, they can be like, ‘Wow, we didn’t even realize that this is occurring in our country,’” said Smith. Fraud connected to digital currencies are now behind the bulk of U.S. internet-crime losses. Americans reported $9.3 billion in crypto-related scams last year, a 66% increase over the year before, per FBI data. To recover stolen funds, the report added, the Secret Service has turned to industry players such as Coinbase and Tether, with one of the biggest recoveries involved $225 million in Tether’s USDT stablecoin, tied to romance-investment scams.
