Major South Korean cryptocurrency exchanges Upbit, Bithumb, and Coinone have jointly announced the delisting of Quiztok (QTCON) effective August 25th at 15:00 KST. This decision comes after an initial investment warning was issued for QTCON. According to the exchanges, the Quiztok foundation's explanation regarding the investment warning was deemed insufficient to address the underlying concerns. After a thorough review of the project, including its development progress, business prospects, and overall sustainability, the exchanges concluded that QTCON no longer met the requirements for continued listing support. This delisting highlights the stringent criteria Korean exchanges apply to listed digital assets and the potential risks associated with less established cryptocurrencies. Investors holding QTCON on these platforms should take necessary action to withdraw their assets before the delisting deadline. ```
