Wow, he has actually 103 Bitcoin in his wallet. He must be really disappointed with losing his wallet.dat. I wish he gets it soon as possible back but that is nearly impossible.
I would kill myself if that happens to me, haha, just a joke, but no one can really be happy if he/she lost more than a one million dollars! I mean, i would not even know how i could react.
That is why the hardware wallets have ever existed, and i remember that i started mining on 2013 and i did not even stored my bitcoins on my pc, everything was on my paper wallet and i switched to hardware lately on 2015.
Indeed, 103 Bitcoin is huge amount and just losing in instant would make you devastated. I also don't know what will be my reaction if that happens on me, perhaps I could be sit on the corner and ask myself "what the hell just happen?".
That is why it is better if we will split up our holdings into different wallet or you should store it in cold wallet like ledger or most secure cold wallet.
