A cryptocurrency trader was found dead Sunday at his home in Seoul, and police are investigating the cause of his death through an autopsy.

The trader, named Choi Yong-guk, has been under pressure from investors for redeeming the investment in Chinese cryptocurrency coins they bought through the trader Choi.

Choi has claimed himself as the Korean agent for issuers of Chinese cryptocurrency issuers, namely initial coin offerers. Choi allegedly bought Chinese cryptocurrencies, including Aergo, NEX, QKC, TUC, Bgogo, and OASAIA, on a lump sum basis and resold them to unknown numbers of investors.

Choi allegedly received refunds from Chinese venture capitalists, but he diverted the money to his family members and his girlfriend. Investors plan to sue Choi’s family members and girlfriend to return the money
