Long story short: yes, our wallet server got hacked and all funds were withdrawn.
Long story short, we're covering this from our own pockets again.
Thank you for the update erundook and ignore the flamers. I too hold a balance on CoinEx and I'm here patiently waiting for news without disturbing the, no doubt, arduous task that you're going through.
I hope you are able to come to a conclusion as to how it was done, and how to prevent it from happening again.
Quick question for you: were all funds from all wallets (altcoins) also targeted, or did they focus on bitcoin/litecoin/other large wallets only?
Thx and speedy recovery.
