The United States Secret Service has silently built one of the largest cryptocurrency cold wallets in the world, seizing nearly $400 million in digital assets over the past decade. This massive cache stems from a steady stream of scam investigations led by the agency’s Global Investigative Operations Center (GIOC), according to a report from Bloomberg.
Unlike traditional criminal takedowns involving cash or property, these operations target the digital underbelly of fraud. Investigators use blockchain forensics, domain records, and open-source intelligence to track illicit transactions. They rely on patient analysis and human error from scammers to unmask identities and seize funds.
At the Center: The Global Investigative Operations Center (GIOC)
The GIOC plays a central role in managing the Secret Service’s crypto investigations. Investigative analyst Jamie Lam explained the team’s techniques during a law enforcement conference in Bermuda last month. According to Lam, agents track crypto funds using blockchain analysis tools and seize wallets once they confirm criminal activity. The cold wallet holding the seized funds now ranks among the world’s largest.
In many cases, the team follows funds from fake investment platforms. Scammers design these platforms to appear legitimate and draw in unsuspecting investors. Victims often see fake profits in their dashboards, encouraging them to deposit more money. Once enough funds accumulate, the scam operators vanish with the money, leaving no way for victims to withdraw.
“That’s how they do it,” Lam said. “They’ll send you a photo of a really good-looking guy or girl. But it’s probably some old guy in Russia.”
Tracking the Tracks: Blockchain Analysis and VPN Mistakes
The agency’s success depends on its ability to exploit the transparency of blockchain networks. Every transaction leaves a trace. Lam’s team follows those traces, often uncovering webs of interconnected wallets. Sometimes, even a brief slip-up can open the door. In one case, a scammer’s VPN disconnected for just a moment, revealing an IP address. That clue allowed investigators to piece together the scam’s infrastructure and trace funds back to the perpetrator.
Domain records and metadata from online ads also serve as valuable clues. Criminals often fail to hide every digital footprint, especially when they reuse names, email addresses, or payment wallets across schemes.
Leading the Fight: Kali Smith’s Global Vision
Kali Smith leads the Secret Service’s strategy on cryptocurrency crimes. Her team has trained law enforcement officials in over 60 countries, equipping them with the tools to track and shut down digital fraud. The Secret Service targets jurisdictions with weak regulations or programs that offer residency to foreign nationals in exchange for investments. These loopholes attract scammers and serve as safe havens.
“Sometimes after just a week-long training, they can be like, ‘Wow, we didn’t even realize that this is occurring in our country,’” Smith said.
These training sessions empower local authorities to recognize and respond to financial crimes involving cryptocurrency. Many scams operate across borders, so international cooperation becomes essential.
Real-World Cases: From Romance Scams to Sextortion
The Secret Service has tackled a wide range of scams. Romance-investment schemes dominate the landscape. In these scams, criminals build emotional connections with their targets over time and then convince them to invest in fake crypto platforms. Victims often transfer thousands or even millions of dollars before realizing the betrayal.
Sextortion schemes have also surfaced, often involving young victims. In one disturbing case, an Idaho teenager sent a nude photo to someone online, thinking the recipient was another teen. The scammer extorted the teen twice for $300 before the victim reached out to local police.
Analysts traced the crypto payments through another coerced teenager, used as a money mule. That trail led to a wallet connected to $4.1 million in transactions. The wallet linked to a Nigerian passport, which eventually led British authorities to arrest the suspect when he arrived in Guildford, England. He now awaits extradition.
The Scale of Crypto Crime in the U.S.
Crypto-related fraud now drives more internet crime losses than any other category in the United States. In 2024, Americans reported $9.3 billion in losses due to cryptocurrency fraud. That number accounted for more than half of the $16.6 billion total lost to internet crimes, according to FBI data.
So far, 2025 has shown no signs of improvement. During the first half of the year alone, crypto-related hacks, scams, and exploits resulted in losses of over $2.47 billion. That figure already surpasses the $2.4 billion stolen during all of 2024, showing a worrying upward trend.
The rise in cases shows how scammers have adapted quickly to digital finance. Victims now lose money faster and in larger amounts, especially as more people invest in crypto assets without understanding the risks.
Industry Cooperation Proves Essential
The Secret Service doesn’t work alone. Recovering stolen cryptocurrency often requires help from industry players. Exchanges like Coinbase and stablecoin issuers like Tether have stepped up to help investigators. They freeze wallets and provide transaction records that assist in tracing stolen funds.
One of the largest recoveries occurred when Tether helped recover $225 million in USDT linked to romance scams. That single case underscores the importance of corporate cooperation. Without it, most funds would remain out of reach due to the decentralized nature of blockchain systems.
Cold Storage: The Agency’s Digital Vault
Most of the seized crypto assets now reside in a single cold-storage wallet controlled by the Secret Service. Cold wallets keep private keys offline, protecting the funds from hackers. This wallet now ranks among the largest globally, although the agency has not officially disclosed its public address.
The Secret Service treats this wallet as a digital evidence vault. Funds remain frozen during ongoing investigations or until courts rule on asset forfeiture. In some cases, the government may return recovered assets to victims. In others, it may auction off the assets, as seen in previous seizures by U.S. authorities.
Beyond Seizures: Raising Awareness and Building Capabilities
While asset recovery remains a top goal, education also forms part of the agency’s broader mission. By training officials in dozens of countries, the Secret Service hopes to build a global network of capable investigators. Scammers rely on slow or inexperienced enforcement systems. Smith and her team aim to change that by raising awareness and boosting capabilities worldwide.
Local law enforcement officers now receive training on using blockchain explorers, tracing wallet addresses, and understanding transaction patterns. These skills help them act faster and prevent losses before they spiral out of control.
The Road Ahead: A Persistent Threat
Cryptocurrency promises financial freedom, but it also opens the door to abuse. The Secret Service understands this duality. That’s why the agency has invested so much in building its crypto expertise.
The $400 million in seizures shows the scale of the threat. It also shows that digital criminals leave trails, no matter how carefully they hide. With the right tools, enough patience, and solid cooperation between agencies and platforms, investigators can recover funds and stop scams before they spread.
But the battle remains far from over. The second half of 2025 could bring even more sophisticated schemes. Scammers continue to refine their techniques, often targeting victims with emotional manipulation and high-pressure tactics.
For now, the Secret Service stays vigilant. With its expanding cold wallet and global network of trained investigators, the agency stands at the forefront of America’s fight against digital financial crime.
