As long as there is no public statement from the coinex staff we are only guessing. Maybe we should wait what is going to happen in a few weeks. I don't think that trying to chase transactions or people will help, you only have more questions and no answers at hand.
Well I think I've gone a little further than guessing.
I have proven that LTC that I deposited to CoinEx has been moved to another address along with another 20 LTC.
This happened AFTER CoinEx became unavailable so only CoinEx staff (or hacker which I feel is unlikely) could have moved it.
It would take 30 seconds to just put something on Twitter along the lines of "CoinEx will be back, improving security". Or even just "We're still here" would be enough for most.
