Not a good news, but it's by far not a shock; we knew that this will be coming rather soon, didn't we?
Everything went to this, first the limitation of the withdrawal limit, then the full KYC. From the experience of Bitmex, I can say one thing:
DO NOT BELIEVE THAT YOU HAVE THE OPPORTUNITY TO WITHDRAW THE FUNDS before the date indicated in the announcement, the end of October. Bitmex at one time also gave six months, and then sharply reduced the term by 3 months, without announcements and explanations of the reasons. Who wants to withdraw funds, send it right now and do not think that you have a couple of months left in order not to go through KYC.
