Novaexchange was not hacked so users still have some hope of being able to withdraw their funds after completing KYC and they have sent alerts unlike Cryptopia who isn't ready to even disclose the KYC procedure and shut doors after saying that the altcoins were not hacked. Months have passed and no positive result.
I haven't heard of anyone successfully completing the novaexchange's KYC, but you're right that Cryptopia didn't even bother with KYC until it went into insolvency.
