I see that it got your attention since the total supply of bitcoins is only 10,000,000 so that wallet holds the 10% of the total supply. I think it is better for us to leave the owner of the said wallet because it is nothing to gain even though we find whoever the man is. The best we can do is educate ourselves to such a degree that someday we will hold the same amount of Altcoins that has somehow close to the price of bitcoins today.
