A Chinese national has been extradited from the Netherlands to the United States to face a money-laundering charge tied to an alleged cryptocurrency investment scam that targeted Americans. The Justice Department said Zheng Zhao, 44, appeared in the Central District of California on October 23 after Dutch authorities assisted with his arrest and extradition.

Prosecutors describe a cross-border laundering route

According to the Justice Department, overseas operators contacted victims through unsolicited social-media messages, phone calls, texts and online dating services. They allegedly built trust, promoted digital-asset investments and directed people to websites designed to resemble legitimate cryptocurrency trading platforms. The sites displayed purported gains, but prosecutors say the money had instead been taken and routed through accounts controlled by the network.

Investigators identified 174 U.S. victims. Prosecutors allege that more than $36.9 million moved from U.S. bank accounts controlled by co-conspirators into one account at Deltec Bank in the Bahamas. Zhao and others then allegedly arranged for the bank to convert the funds into Tether's USDT stablecoin and transfer it to a digital-asset wallet controlled in Cambodia. The government says the USDT was subsequently distributed to leaders of scam centers in Cambodia and neighboring areas.

Crypto was one stage of a wider financial chain

The allegations show why digital-asset fraud investigations increasingly span both conventional finance and blockchain infrastructure. The claimed route began with U.S. bank transfers and shell companies, passed through an offshore bank account, and only then entered a stablecoin wallet. That sequence matters: it does not establish that stablecoins or cryptocurrency platforms are inherently fraudulent. It describes how prosecutors say multiple financial layers were used to obscure the source and destination of victim funds.

Extradition moves the case into a U.S. courtroom

Zhao was charged in August 2025 with conspiracy to commit money laundering. The Justice Department says the offense carries a maximum penalty of 20 years in prison if he is convicted, although any sentence would be determined by a federal judge under applicable law. He was ordered detained after his first court appearance, according to the U.S. Attorney's Office for the Central District of California.

Eight alleged co-conspirators have already pleaded guilty, the department said. They include ShengSheng He and Jingliang Su, who pleaded guilty to conspiracy to operate an unlicensed money-transmitting business and received prison terms of 51 months and 46 months, respectively. Those earlier outcomes do not determine Zhao's guilt, but they provide context for the broader investigation prosecutors describe.

The alleged approach relied on trust before technology

The recruitment channels described by prosecutors are also important for consumers and compliance teams. The alleged scheme did not begin with a blockchain exploit. It began with personal contact and false investment interfaces that appeared credible to victims. By the time funds reached a stablecoin wallet, the social-engineering stage had already persuaded people to authorize bank transfers. That makes identity checks, unusual-payment monitoring and rapid fraud reporting relevant alongside blockchain analytics.

What remains unresolved

The public release does not provide a final accounting of recovered funds or say how much, if any, has been returned to the 174 identified victims. It also does not establish that Zhao personally controlled the full $36.9 million. The case is part of the Justice Department's Cyber-Enabled Scam Initiative and was investigated by the U.S. Secret Service with assistance from several federal agencies and Dutch authorities. A criminal complaint is an allegation, and Zhao is presumed innocent unless proven guilty beyond a reasonable doubt.
