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.
In case that it is true, it is strange. I mean unless we are talking about some kind of illicit funds, I don't see why someone would not come forward as you say. Then again, if they were illicit at that amount I would wager that someone would connect the dots.
Either way, it is nice to see monero moving up given all the attacks from totalitarian freaks that it has had to endure in recent history.
