Chu said he was attacked while walking alone at night. The attackers took his smartphone and left a knife wound on his arm. Chu said he spent the whole night at the police station, but his problem was never resolved. Therefore, Chu urged other participants of the Ethereum Devcon event to remain vigilant, especially after dark.

Another co-founder of the Rooch Network, Jole Star, said he and Haichao Zhu would contact local stores near the crime scene to review CCTV footage. This could help in catching the attackers, the victim's partner hopes. He urged people not to go out in Bangkok at night and not to talk on the phone while walking.

Ethereum Devcon is an annual event organized by the Ethereum Foundation. This year's conference is scheduled for November 12 at the Queen Sirikit National Convention Center in Bangkok. The event is expected to be attended by major players in the crypto industry, including Ethereum co-founder Vitalik Buterin and Ethereum Foundation Executive Director Aya Miyaguchi.

This is not the first attack on an Ethereum Devcon participant. A similar incident occurred in July in Brussels with the head of Kilt Protocol Development Department, Rishant Kumar.

Recently, Moscow teenagers who are engaged in crypto trading have become victims of criminals. The robbers broke into their apartment and stole nearly 1.4 million rubles. In September, Nick Drakon, the CEO of the research platform Revelo Intel (NASDAQ: INTC), was forced to transfer all his cryptoassets to the criminals under the threat of violence.
