According to Foresight News , citing The Paper, in May 2024, Zhangjiajie police launched an investigation into an online gambling case based on an anonymous tip, and Li Dong, a cybersecurity engineer from Shenzhen, was listed as a suspect. In September, the Zhangjiajie Public Security Bureau in Hunan Province summoned Li Dong on suspicion of "operating a casino." Zhangjiajie police seized 103 bitcoins from his digital wallet, which were converted into more than 49.61 million yuan. Li Dong was subsequently released on bail. However, on the seizure decision and bail documents, the charge against Li Dong changed from "operating a casino" to "illegally obtaining data from a computer information system." Four days after being released on bail, Li Dong was taken away again by the Xuchang police in Henan Province. On September 17, 2024, Li Dong was criminally detained by the Changge Public Security Bureau on suspicion of operating a casino. In October, Li Dong was arrested by the Changge police. At this time, the charges against him were "theft and infringement of citizens' personal information." In 2025, the Weidu Branch of the Xuchang Public Security Bureau and the Changge Public Security Bureau seized approximately 80 Bitcoins, with a value exceeding 40 million yuan.
According to the prosecution, in 2020, Li Dong exploited a program vulnerability in the server of the overseas online gambling website "Kaiyun Sports" to steal the personal information of over 1.84 million Chinese citizens, including individuals from Xuchang and Changge. Furthermore, Li Dong selected agent accounts with high commission rates and numerous downlines from the "Kaiyun Sports" gambling website's agent accounts, replacing the commission bank accounts of these agent accounts with bank accounts under his control, stealing a total of over 35.5 million yuan in agent commission funds from the "Kaiyun Sports" gambling website. Of this, over 6.44 million yuan was transferred to 13 bank cards purchased by Li Dong; the remaining 29.05 million yuan was used by a certain group to purchase cryptocurrencies such as Bitcoin and transferred to Li Dong's wallet.
