OKEx Suspends Withdrawals, Says Key Holder Not Available Due to Cooperation With Investigation

OKEx has suspended all cryptocurrency withdrawals indefinitely, saying one of the exchange's key holders has "been out of touch" with the exchange because they are "currently cooperating with a public security bureau in investigations." OKEx' CEO later said the investigation is due to the key holder's "personal issue."

• "OKEx’s other functions remain normal and stable and the security of your assets at OKEx will not affected," the notice read. "We will resume digital assets/cryptocurrencies withdrawals immediately once the concerned private key holder is able to authorize the transaction."
• OKEx CEO Jay Hao claimed the key holder's cooperation with officials was due to a "personal issue" and the investigation would not affect the business, according to a Weibo post.
• Taking to Twitter, Hao indicated that non-crypto withdrawals should still be processing, claiming that all non-crypto or digital asset operations were unaffected.
• Later on Friday, OKEx said in a statement: "We are unable to disclose the nature of an ongoing investigation but would like to assure all OKEx users that their funds are safe and that all other functions on OKEx are unaffected."
