Better to use a trusted exchange with known staff members or at least having real names and locations.
This exchange is scamming users, or else why would it shut down every possible contact with it?
The "hack" story will never end apparently.
Trust me (heh). All the licensing, all the recognisable and known staff members, all the real names and locations won't stop neither hacks nor exit scams, should they happen. Ask Mt Gox users, who trusted everything in it and its owners. Ask people who've been scammed on this forum, by trusted and legendary members. I of course risk my coins with trusted people, for some opportunities, but I'd never give everything I owned to anyone, not the Pope, not even God. Because shit happens when shit happens, and you've got no recourse if you don't control your coin.
