The hack story may be or not be true but... What has that to do with cryptsy closing and leaving a lot of people without their funds? I mean, The hack/theft of sometime ago cannot be used as an excuse to leave people without their money now. If you are stolen is you (the owner of the exchange) who has to accept the loses as it is you (and not the end user) who got stolen.
It is curious they could have stayed open and started using running profit to pay people back, maybe they wouldn't be able to do this totally but it would be a start. Its 10k coins not 600k.
Whether 10k or 600k, both are very big in numbers when it is compared to their values in USD...
And what if one is not willing to return even if he is speaking truth???
