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
His Address 166BuLPWHUjqoqiYp5rGE3B5r5AmqgHpoL Final Balance 103.20832384 BTC
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."
It is Very sad to hear news like this. Although he lost when the bitcoin value was very low at that time. But I'm sure, everyone will be very disappointed if they lose their bitcoin. He collects little by little from the mine. After long collecting, he lost his wallet. Very sad. Hopefully this incident does not happen to us all.
But i have read an article where i found about four million btc gone forever.
