They also apparently immediatly addressed the situation on their twitter stating that they'll compensate users through undecided means yet. Most of the divulgued losses are NEM coins so far, and i've read that some ripple funds have also been moved apparently from Coincheck since the hack.

So chances are that the biggest losers from this event will be Coincheck themselves for losing trust of customers, and of course NEM prices will most likely be affected and slide a bit back down from the incredible run up that's been observed by NEM.
