Do you rembember how many bitcoins you had? it's very sad you were unable to restore your wallet, but what can you do. I heard
the story that once some guy payed for the pizza 10 000BTC, and was very happy about that, to be able to buy something with virtual money:)
I wonder if the pizzaguy still has this wallet, if he does, this means he is a millionaire (10 000BTC x 850USD=8 500 000$)
From a newbie to another. I started mining BTC when it was pretty new, somehow I stoped and didnt think of mining for a year or two. Found out later that the BTC value had gone up considerably, but could not recreate my old wallet :-(
So now im back again, mining scrypt coins, hoping to make some money on the side =)
I wanted to recomend two multipools, since I think its the best way to mine efficiently.
Check out switchercoin.com and megamultipool.com I have been mining on switchercoin for a while and it works fine, today I started mining on megamultipool just to see how its like.
I wish you the best in your mining adventure =)
