Well, you hadn't bother about those Dogecoins since 2014, hadn't put them on well-protected digital wallet and now in 8 years complain that someone hacked them. Just don't bother about Doges again. Faith the reality, you lost your Doges forever and can do nothing with this. Your situation might be a good experience for you to protect crypto in future.
Yes, you may be right, understand that they weren't actually worth very much until the recent activity so I hadn't really thought about them since 2014.
It was not an inside job.
I think perhaps my PC did have some malware and I did have an old wallet.dat file in a folder.
I have formatted the hard drive and changed all my passwords to unique passwords using a generator.
Thanks for all your comments,
Does anyone know how to use
https://ciphertrace.com/financial-investigations-and-blockchain-forensics/ or anything similar as I would really like to know which exchange received the stolen coins so I can at least make an inquiry.
Thanks,
