On October 16 OKEx suddenly stopped withdrawals.
As it was reported, OKEx originator Mingxing Xu, also known as Star Xu, has been questioned by the police. The head of the company was asked nearly a week ago and hasn't attended to work for some time. The news comes shortly after OKEx delayed withdrawals of cryptocurrency on its platform. According to the exchange, OKEx’s private key holders are working with a public security bureau in an ongoing investigation.
This is not the first time that Xu has spoken to police. In September 2018, he co-operated with authorities over accusations of fraud regarding a small-cap cryptocurrency.
