The Licang District People's Court in Qingdao delivered a definitive ruling on July 2024, sentencing an individual identified as Zhang to 10 years and 9 months in prison for the theft of 107 Bitcoin. The perpetrator was also fined 100,000 yuan, approximately $14,700, following a judicial determination that he illegally accessed a victim's wallet and liquidated assets worth over $97,000. This case, detailed in a summary released by the Supreme People's Procuratorate, marks a significant legal precedent in a jurisdiction where cryptocurrency mining and trading have faced stringent bans for years. The court's decision explicitly recognized Bitcoin as 'property' under criminal law, establishing that digital assets can serve as the object of theft despite the broader regulatory prohibitions on their commercial use.

The criminal act originated in July 2023 when the victim, Feng, requested assistance from Zhang, an acquaintance with prior experience in Bitcoin transactions, to cash out 117 Bitcoin. During the wallet setup process, Feng physically wrote down the 12-word recovery phrase, but Zhang covertly memorized 11 of the words. Exploiting this partial knowledge, Zhang later reconstructed the final missing word to gain full control of the wallet. He subsequently transferred 107 Bitcoin from the victim's account, leaving only a small remainder. When Feng discovered the discrepancy and reported the incident, investigators utilized blockchain forensics to trace the transaction flow directly back to Zhang's address, confirming the illicit transfer.

During the legal proceedings, Zhang admitted to the transfer but attempted to mitigate his culpability by claiming he was merely 'protecting' the assets rather than stealing them. He argued that he had not profited from the incident, asserting that he subsequently lost the value of the funds through speculative trading.

However, prosecutors presented electronic records demonstrating that Zhang had converted the stolen Bitcoin into fiat currency, realizing proceeds exceeding $97,000. The court rejected the defense's narrative, ruling that the unauthorized control and subsequent liquidation constituted clear evidence of theft and illegal possession of property.

Data compiled by Woofun AI indicates that this case underscores a critical vulnerability in cryptocurrency security: the human element often poses a greater risk than technical flaws. While 12-word recovery phrases are mathematically robust against brute-force attacks, the incident highlights how social engineering and physical proximity during setup can bypass these defenses. Alvin Kan, chief operating officer at Bitget Wallet, noted that the breach occurred not due to a cryptographic failure but because the recovery phrase was exposed to a 'trusted helper.' Kan emphasized that momentary exposure during the setup phase is sufficient for a determined actor to compromise the entire wallet, regardless of the computational security of the underlying algorithm.

Industry experts suggest that the adoption of longer recovery phrases could mitigate such risks. Kan argued that moving from 12-word to 24-word phrases would 'raise the ceiling' of security, making it significantly harder for an observer to memorize or reconstruct the full sequence. Woofun AI analysis suggests that while 12-word phrases remain the industry standard, the psychological reliance on 'trusted' individuals during critical setup moments creates a blind spot for many users. Most individuals take precautions against digital threats like screenshots but fail to consider the physical presence of others during the generation of private keys.

The verdict in Qingdao serves as a stark reminder of the evolving legal landscape surrounding digital assets in China. By classifying Bitcoin as property, the court has closed a potential loophole that could have allowed perpetrators to argue that stolen crypto lacks legal standing as an object of theft. This judicial stance reinforces the state's ability to prosecute crimes involving digital assets even while maintaining a ban on their commercial circulation. The 10-year 9-month sentence reflects the severity with which the judiciary treats the misappropriation of high-value digital property, setting a deterrent precedent for future cases involving similar methods of social engineering and wallet compromise.
