This guy has lost 103 bitcoins he mined back in 2011 and then lost his wallet dat file similar to what I have done but wow this guy must be gutted the amount of money he has lost compared to me

So many people have the same problem and I wonder just how much Bitcoin is stuck not being able to be used

He says "I used to mine Bitcoin back in 2011 and I lost my wallet.dat file (through several stupid moves on my part). It's got approx 103 BTC in it, anyone is welcome to it, I've given up trying."
Wew! This is really one sad story to hear. It's more heart breaking than the scene of Titanic sinking (I guess).
Imagine the value a 103 bitcoin holds (especially December last year when it rose to USD 19,000 a piece). The guy must have been pretty devastated.
But this is the reality of a lost wallet in return for stronger security. That is why it has been overly stressed to never lose your details relating to your wallet access. That is why one should never be careless of these wallet-related information. Keep a local or online copy whenever possible. Better yet, write it down somewhere safe and hold dearly on to that.
Hoping the guy you are talking about learn from his mistakes.
