I think its a safe bet to count this as a loss now. Its pretty much shot itself.
Even if by some miracle the exchange was ever being developed, how is anyone supposed to have any faith in the guy running it after it goes live. Reputation has been ruined by the way he is hiding in the dark at such a crucial time, so many unanswered questions.

Would you seriously recommend anyone send their bitcoin to this guys operation after the way he is treating the initial investors. Sorry, but I just wouldn't do it.
Gonna need a huge turnaround to see this ever coming back to something near a trusted project. I just dont see it happening.
