Take care with that exchange. I opened a ticket about ORB, pointing out that the network forked at 417k, and they seemed to be on the old version, so my deposit was never going to arrive. That was 5 months ago. As of today I am still waiting for a response.
Yes, they resume ORB trade.
BUT seems they forgot update wallet to latest (1.4.2.x) version - deposits/withdrawals actually not working.
... aaaand there we go.
edit: I just logged in to check, and it's still not credited. 314080 confirms.
