I understand that no details can be revealed during the ongoing investigation. But what is the point of the news then? I bet people that have suffered from the hack are sick from hearing such statements as "excellent progress is being achieved" while seeing no actual progress on the matter. Police should not only arrest the thieves but retrieve all the stolen money from them.
unless it was an inside job and the employee is still in NZ, that's probably not gonna happen. the money is gone. just ask mt gox victims how easy it is to claw stolen money back in a crypto heist.
it's too bad, the timing of it all. i'll bet if this happened during the altcoin boom, they could have easily crowdfunded a recovery (bitfinex style). everyone wanted into the market back then. at this point, there's little chances of that happening.
