This morning I moved all the BTC I made above my starting investment onto BTCe. I don't intend to use MT Gox for trading but it's good to know I have coins on a liquid, safe if completely fucking bonkers, exchange.
So you're moving from an incompetent company managed by script-kiddies which at least is officially registered in Japan to an "exchange" ran by unknown Russian people who never responded claims of being hacked and users' coins stolen multiple times.
Not that the rest of the "exchanges" do inspire above-joke confidence, unfortunately for all of us.
Good luck
