The bitcoin exchange OKEx has suspended cryptocurrency withdrawals on its platform as its Chinese founder faces policy inquiries "in cooperation with an investigation."
OKEx founder Xu Mingxing was taken at least a week ago and hasn't appeared in a work-related social media group recently, according to a person close to the company. It's not clear what the investigation is about. There have been signs of a renewed crackdown on money-laundering activities on over-the-counter (OTC) trading platforms of cryptocurrencies.
