Was it confirmed that this was the case or does it still remain speculative?
Still speculative, but more likely than not. I still am not sure how it’s possible, given that there hasn’t been any body claiming they lost the $330 mil. I mean at that point, fuck being anonymous if you have the keys to the wallet that proves you were the owner of the wallet - coins are gone by that point, just proves you were the victim, and maybe some sort of law enforcement might be able to help try to track who did it.
