I remembered this address because of the time when I had this purchase, it was within 2 pm
I can't understand the concept.
it was 2 PM and you remember exactly an alpha numeric code of something that you really didn't give a damn about (since you lost it without even backing up your private key?)
do you remember the address but not to make a back up? or to don't sell your laptop? ( maybe selling a portion of those bitcoins prevented you from this laptop sale...) mmm

I had also forgotten to say the date because it was the holidays and I had also told my friend when I made this purchase he made me 19400 btc I was just surprised because in my head this n was not much
and for the private keys he didn't tell me anything
he told me to buy and i listened to him that's all
