It seems that statement about the withdrawal problem has been discussed in the official telegram so we should wait until January 16, if indeed until that date there is still no withdrawal available then we can discuss this in the Scam Accusations
That's we can do for now is to wait until they fulfilled their issues at the given date, making noise won't help, at least they are still responding compare to IDAX who just suddenly lost from the space. Hope that BCNEX will settle this issue so that their reputation will not be at risk, but still keep yourself updated all the time.
Surely, I was a participant of Bcnex airdrop program and i thought If they open the withdrawal function until 20 Jan we can believed them. The support team doing on their social channels and responsive almost questions now.
