I used to get paid via bitcoin. I used it for online necessities such as webhosting and domain names. Then I made a backup in 2012 and a few others. Then my friend used my machine and erased my hard disk accidentally (sure) so years later here I am knowing that I have transactions from 2013 trying to resurrect my wallet.dat file from my backup. Unfortunately, I can only find my 2012 wallet so I don't have my new addresses that I had been putting out there for fun. I'm sure no one paid anything and I probably have very little bitcon if any, but since it's an older backup I'm pretty sure I no longer have that info and its lost. Or maybe I'm wrong? Thanks
