Don't use crypsty to trade NXT or you will lose you money.
I have a broken withdrawal :
Nxt NXT-G8MD-GZZA-FNRS-52DDF 10585.18248105 NXT Yes 2014-08-17 14:19:56
Processed TrxID: @ 2014-08-17 14:30:41
(See the no id, and the confirm set to yes)
They don't answer to you ticket after that, even if you give them the link to check that the transaction is not in the blockchain.
10585 Nxt is a lot of money for me, I don't know what to do with them
