The other day I signed up and deposited some alt coins, sold them, and withdrew 0.2 BTC. Everything was slow, but it worked just fine. The following day I deposited a bigger batch of alts, sold them, and requested a withdrawal of 0.36 BTC. After a couple of hours I logged in to check on my withdrawal and they had cancelled the withdrawal and have disabled my access to my wallets. I can see the BTC sitting in my account but anytime I try to open my wallets it says "You are disabled".

I have an open support ticket that hasn't been answered yet and they completely ignore you on their twitter. I recommend that you stay far away from this exchange.
