A few years ago I purchased some bitcoins from MtGox and decided to retrieve them to the wallet on my PC.
Now without getting into detail I got sick of the headaches and ended up uninstalling the program before I received ANY coins. In retrospect I could not have been a bigger idiot.
Now these coins are worth a small fortune and I've done everything I could think of to retrieve them. I contacted MtGox and all they could say was that the network says the transaction shows as complete. I have extensively and on a byte level searched the PC in question for remnants of my private key, with no success.
Which brings me to the question at hand.
I still have my public key, the knowledge the coins were never received and access to the MtGox account they were sent from.
What can I do? MtGox simply left it at "the network says it was completed, therefore fuck off"
