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.
Actually who is this guy ? Does he has a name ?
What a pity , there's nothing to happen to that supply if it will not be unlocked. And we must make use of it. Can't he not recover the files in his/ her laptop or computer. If it was deleted it can recovered. But I hope he or I can recover it I hope I' a genius hacker.
Please try, if stored in offline wallet of course such risks can occur, I'm sure if you want to restore it takes more than 10 years if lucky, it is because bitcoin private key is designed with difficulty and high encryption.
