Quoting from a Hotbit Twitter tweet:

"It's time to take a bow🙇 For 5 years and 4 months, the Hotbit team has been proud to participate in a wonderful crypto show with 5 million users. However, it is with great regret that we have made the decision to stop all CEX operations from May 22, UTC 04:00. We kindly ask all users to withdraw their remaining assets before June 21, UTC 04:00."

The essence of the above message that has assets on hotbit withdraw immediately, because hotbit will close!
