it has been said more than a million times: don't keep anything on exchanges but people never listen. it is not just about them running away or getting hacked now, it is about government closing them down. in this case it may be temporary.
besides there were enough time for people to withdraw in the beginning.
They will enable the cashier feature in next month, not permanent shut down, it is definitely temporary if you read their announcement. The price is stable, not dumped by this news.
since when do you trust an exchange announcement?
i am not saying they are lying or they will close down permanently, i actually agree with you but all i am saying is that Cryptsy was telling its users that they will open up withdrawals and allow people to take their coins out. they even released a list of altcoins you can withdraw but in reality nothing could be taken out of the exchange after they closed down their site.
