Exchanges generaly keep majority of coins in offline (cold) wallets so it can happen that big withdrawals are delayed. With TEK, extra trouble might come in a form of too many
really small unspent inputs - just imagine if someone is PoW mining and sending mined coins to Cryptsy as soon as they matured or sending just coins staked from 1 TEK block
rewards, 1000 TEK would be 1000+ transactions which means if you attempt to withdraw that much TEK in one go and Cryptsy picks 1000+ smaller unspent inputs then the size
of transaction could be so big that Cryptsy TEK wallet would refuse to create it and throw an error instead. Just withdraw less coins per request and it should work fine.
