That is a problem - they opened wallets,but did not give us balances.They said that BTC,LTC,BTCD and XC were stolen,so balances for other unaffected coins should be OK and users will be able to withdraw them to the last one.But in fact,this is not happenning.There are some coins in wallets,but not enough to cover members balances.
How that could it be? - Well if not robbed(and Cryptsy did not give any evidences for that beside BTC,LTC,BTCD and XC) only one thing could happen - they used coins which did not belong to them,sold them to cover their expenses and make Cryptsy live another day(plus possibly sold some of them on other exchanges to obtain necessary BTCs for running exchange and calm people).I cant see any other explanation.
1) More coins were lost than Craptsy has admitted to losing (DRK/Dash withdrawal problems were first reported 18 months ago)
2) Craptsy's database has been hacked (evidenced by the phishing emails and failed login attempts)
It's possible that whoever hacked their database, also moved coins from your account into their own...
