If an exchange has all the coins they hold for their customers, there is no reason for any delay. They might have coins locked up in cold wallets, that shouldn't take more than 24 hours to move to hot wallets. The delays must be caused by something not right.

Whatever happens, when withdrawals are resumed with no delays, confidence is lost and it will be difficult to rebuild trust. I think Crypsy is not going to fold, it think it is going to fade out of the crypto scene in a year.
