A cryptocurrency transaction at a luxury hotel in Jeju City, South Korea, ended in tragedy as a Chinese man was killed, prompting swift action from local authorities who have arrested four Chinese nationals suspected of the crime. The case highlights the growing security risks associated with unregulated peer-to-peer (P2P) crypto trading.
Murder at a Luxury Hotel: Crypto Deal Turns Fatal
Officers from the Jeju Western Police Station reported that a 30-year-old Chinese man was found dead in a luxury hotel on February 24, allegedly during a cryptocurrency trade. Authorities believe the victim was stabbed and robbed of 85 million won (approximately $59,318) in cash.
The crime was discovered after a friend of the victim contacted authorities, stating that the man had gone to purchase crypto but stopped responding to calls. Officers arrived at the scene and confirmed the murder.

Four Chinese Nationals Arrested, Suspects Tried to Flee
Police have detained four Chinese nationals in connection with the murder, including a 30-year-old woman, a 30-year-old man, and a 60-year-old man. One of the suspects, a woman, turned herself in at Seongsan Police Station shortly after the crime. The other three were arrested at Jeju International Airport as they attempted to flee South Korea.
Authorities have confirmed that all four suspects entered South Korea on tourist visas and are currently under investigation to determine the full motive and circumstances of the crime.
Jeju’s Growing Crypto Crime Problem
This murder is not the first crypto-related crime in Jeju this year. On January 21, South Korean authorities arrested a gang of six Chinese nationals for allegedly stealing $580,000 worth of cryptocurrency from a victim during an over-the-counter (OTC) crypto deal at another luxury hotel.
According to police reports, the victim had agreed to sell crypto for $690,000 in cash to the group. However, after making multiple transactions, the suspects attacked the seller, stole the cash, and fled with both the fiat and digital assets.
Police later tracked down and arrested the gang, recovering a suitcase filled with South Korean 50,000 won bills, suspected to be part of the stolen money. Authorities also believe the suspects forced the victim to transfer additional funds from their mobile wallet, escalating concerns about the security of P2P crypto transactions in the country.
South Korea Tightens Crypto Crime Enforcement
In response to the rising number of crypto-related crimes, the South Korean government has announced plans to strengthen enforcement against blockchain and digital asset fraud.
The Securities and Exchange Commission (SEC) will launch a new Cyber and Emerging Technologies Unit in March 2025, specifically aimed at tackling crypto-related fraud and financial crimes. This initiative is expected to enhance investor protection and market stability as South Korea positions itself as a regulated crypto hub.
Meanwhile, South Korean law enforcement continues to crack down on illicit activities, warning that unregulated crypto transactions, particularly OTC cash deals, pose significant security risks.
What’s Next?
The brutal murder in Jeju underscores the dangers of peer-to-peer crypto trading without proper legal oversight. With crypto adoption rising globally, South Korea’s approach to tighter regulations and law enforcement coordination could serve as a model for other nations seeking to curb illicit activities in the crypto space.
As authorities continue to investigate the suspects and track stolen assets, the incident serves as a stark reminder that security measures must evolve alongside digital finance. The crypto industry—and regulators—face a critical challenge in balancing innovation with user safety in an increasingly high-stakes trading environment.
