You informed me and the community about this sad issue.
I will change your new walletaddress with the old walletaddress on the list of the Proof of Interest campaign.
So you are still in the Proof of Interest campaign!
Thanks for your nice words!
Thanks for letting me stay in the Proof of Interest Campaign. I really appreciate it. I have one question though: Do I still need to have a minimum of 500 XMG to receive interest, or will it be based on my previous balance from the other address?
Thanks! That is really nice. I guess that I would be able to recoup my losses after all. And one thing that I have learned so far is to always make more than one copy of the wallet.dat file to prevent what have happened to me before. Now I have made sure to backup the new wallet in a safe place and the same is distributed among different storage mediums including the cloud protected in an encrypted file container (TrueCrypt)
an additional step that you can consider taking, that many people do for backup purposes, is recording your private key somewhere. I keep mine in a notebook written in pen. You can use that key to recover your coins if you somehow manage to lose your actual wallet.dat file. It is just another layer of security and occasionally taking the time to record it can mean the difference between recovering your coins and not.
Sorry for your loss and don't feel too bad, I think most everyone learns the hard way about backups at some point.
