i never had problems with cryptsy besides slow withdraws all was ok, at least for me; I withdraw all my money from them some weeks ago, i dont know if you can consider them safe now, but from what im reading at his trollbox and here with some new threads, i will not come back yet to that exchange.
Lets w8 a little bit more to come back again...i am perhaps too wary, but i dont want to risk anything.
edited: his withdraws are just something like a joke.... thats another bad point for them...
