Chinese Man Sentenced to 12 Years for Stealing Friend’s Bitcoin

A Chinese court has finalized a 12-year and seven-month prison sentence for a man convicted of stealing and selling Bitcoin belonging to an acquaintance. The case, which highlights the growing legal scrutiny around cryptocurrency custody and trust, was decided by the People’s Procuratorate of Changshan District in Fuzhou City.

Theft Through Breach of Trust

According to court documents, the convicted individual, identified only as Lin, was asked by the victim, Wang, for assistance in cashing out Bitcoin in late 2020. During this process, Lin secretly obtained the private key to Wang’s cryptocurrency wallet from his computer. He then transferred four Bitcoin to his own account and subsequently sold the assets, realizing an illicit profit of approximately 900,000 yuan (about $124,000 at the time of the theft).

The victim did not discover the missing assets until 2024, when he reported the theft to authorities. This led to Lin’s arrest and prosecution. An appellate court upheld the original sentence, which also included a fine of 300,000 yuan (approximately $41,000).

Legal and Market Implications

This case underscores the legal risks associated with self-custody of cryptocurrency, particularly when relying on third parties for technical assistance. In China, where cryptocurrency trading has been effectively banned since 2021, legal cases involving digital assets are often handled under broader theft or fraud statutes. The severity of the sentence — over 12 years for a theft of roughly $124,000 — reflects the serious view Chinese courts take on crimes involving digital assets, even when the value is relatively modest by international standards.

What This Means for Crypto Owners

For cryptocurrency holders, this case serves as a stark reminder of the importance of private key security. The theft was only possible because the victim shared access to his computer and wallet credentials. Security experts consistently recommend using hardware wallets, never sharing private keys, and avoiding assistance from untrusted parties for transactions. The long delay between the theft and its discovery — nearly four years — also highlights the difficulty of tracking stolen cryptocurrency without robust record-keeping.

Conclusion

The finalization of this sentence in China adds to a growing body of case law around cryptocurrency theft globally. While the value stolen was not exceptionally large, the length of the prison term signals that courts are treating digital asset crimes with increasing severity. For readers, the key takeaway is that cryptocurrency custody requires rigorous personal security practices, and that breaches of trust can have severe legal consequences for perpetrators.
