How much was actually stolen, is there an exact figure for this? And apparently it wasn't an insider job and their central servers were not infiltrated. But still, a lot of users were hacked. That's something strange right there that needs explaining imo.
The Korean exchange has already said that they are paying back their customers after the thefts. The OP, by making that title thought he can start something. 
No. They are only refunding $870 per user affected, it seems. So it is nowhere near the magnitude of damages that have been actually done to the individual user accounts, because they're only paying back the loss in personal info, not the financial losses.

Bithumb have promised to compensate its users for loss of personal information amounting to $870 per user (despite losses exceeding this amount)
