oh my god that's the saddest thing I have heard this week. If I had such an amount I would backup my private key 10 times. I wonder how he actually lost it, must be some very bad luck as I'm sure he had backup but then he lost it and never recovered it again. I do think that this happens and sometimes it happens for a reason God controls your life so if he did not lose the bitcoin maybe there will be something will happen to his life or bad happen but we really don't know. If I was the guy it would be really sad and disappointing but everything happens for a reason and what he can only do is to move on and keep earning with bitcoin
