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's the purpose of anonymity if there is a name in a transaction?
Maybe, he lost his key because he never really care about the importance of bitcoin back in the year that it has no value. If that guy is living right now probably his life is miserable.
Lesson learned:
We must keep our private keys.
