They working on this exchange? As i see exchange seems working, but there is any volume and last post in twitter was in March.

Sometimes it is really very hard to tell which project would succeed, the way i see EOSex during the campaign period i could swear it will be among the very successful and honest project around, unfortunately nobody has the answer what is currently going on with them, lots of complains from members in their telegram with no convincing response, i wonder how long it will take for wallet to sync fully so that trading can be resume.

There are nearly 9000 people in this group and everyone has a different idea of what the "appropriate" level of updates should be. In fact, we used to give more frequent updates but, every time I did, people would immediately start sending nasty responses calling us/me a scam and saying "why didn't you guys do this properly" or "why didn't you guys do this a different way". Everyone wants to weigh in on what "they" think should have been done. And then comes 100 other more detailed questions. People want to ask all sorts of details and then the complaining continues. But, as I said a couple weeks ago, the tech team is working on it and, updates will be given when there is something to update. There is no point in repeating the same news every day and then have people repeat the same abusive comments. Having said that, you just got back your ETH yesterday, instead of being pleased, you decided to immediately continue to complain. So, even when people get their tokens back, we still get complaints. So, do you get now why it's difficult to make any comment here now. Anyway, as mentioned before, the tech team says they are still working on the other wallets. When there is an update, it will be posted here. Thanks

Some information from admin chat (TG):

there is nothing else you can do but wait til they do an honest to goodness job, i tried withdrawing mine but same thing happen. he said the technical team is different from the executive like himself, basically he meant the technical team has its own CEO.    if you think you profit because you deposit EOS to get some airdrops now they are screwing you up for it.

The OP is still mentioning a lot of prestigious partners for EOSex - did anyone try to contact any of them to ask if anyone has any clue on what's going on with the project?

It would have been an appropriate thing to do during that time. I'm not sure about the project anymore so the only thing that I can also say is wait. Be reminded that I'm no part of the team. I was just asked to moderate the thread and got paid as well. Those prestigious partners somehow appear to be right as the EOSio tweeted it themselves thru their account. I wish the team could fix issues as soon as possible.
