On March 13, 2026, the Taipei District Prosecutors Office formally filed a public prosecution against the Bijing Exchange Group, with a total of 10 defendants being indicted. Among them, "Cryptocurrency Goddess" Chang Yu-ting (Bijing's COO) and her brother Chang Han-lin (Bijing's CEO) were each sentenced to 12 years in prison, and the actual person in charge, Liu Yu-sen, was sentenced to 8 years in prison. The lawyer involved in the case, Cheng Hung-wei, and the other defendants were also individually indicted and sentenced.
Bijing Exchange was established by "Jingui Technology Company" and officially started operating in June 2021. It presented itself as a legitimate virtual asset exchange, but in reality, it was closely linked with the fake investment fraud applications "Yongshuo Investment" and "Hongjia" to help fraud groups handle and transfer the proceeds of crime.
The investigation revealed that the Coin Group assisted fraudsters in handling NT$120 million in illicit funds, with a total laundered amount reaching NT$150 million. There were 46 victims, all of whom were victims of fake investment scams.
USDT multi-layered transit disrupts the traceability of funds.
This case utilizes blockchain-based payment technology to sever the money flow. Prosecutors stated that the fraud ring first guided victims to convert their funds into USDT (Tether), and then transferred the funds through a multi-layered wallet system designed by the CoinEx group, creating a "breakpoint" in the money flow and significantly increasing the difficulty for investigators to trace the fraudulent activities.
Accomplice You Shaoyu was responsible for providing TRON's native token TRX as a gas fee for each on-chain transaction.
Between July and September 2023, a total of 55,240 TRX were transferred into his wallet. Another accomplice, Hu Chongxian, controlled multiple USDT wallets and was responsible for scheduling funds as intermediary nodes, completing multiple large transfers in just a few months.
One of the funding lines recorded 19 transfers between June and September 2023, totaling 3,767,185 USDT. Through cross-wallet flows, each layer created a new starting point for the money flow, making it difficult for investigators to reconstruct the complete funding path.
A brother and sister startup founder in the financial industry teamed up with lawyers to package "legal consulting" services.
Chang Han-lin was not an unknown figure in the early days of Taiwan's cryptocurrency circle. He served as the Chief Strategy Officer and Chief Marketing Officer of the local exchange Cobinhood, possessing considerable industry experience and connections. His sister, Chang Yu-ting, is active in the crypto community as the "Cryptocurrency Goddess," serving as the Chief Operating Officer of CoinEx.
The siblings, who were once very famous in the early days of the crypto world, are now facing a lawsuit, which has drawn regret from many veterans in the crypto.
Another notable figure in the case is the lawyer involved, Zheng Hongwei. The prosecution alleges that Zheng Hongwei, under the guise of "legal consultation," provided cover and assistance for the group's money laundering activities, for which he was only paid NT$180,000. However, during the trial, he claimed to be unaware of all the key issues, which led the prosecution to believe that he was deliberately avoiding the issue and was actually using his identity as a professional lawyer to assist in money laundering.
