I have a family member who got an email from blockchain stating:
This is an automated notice that your wallet account has been credited with funds in the amount of 0.54798743 BTC.
I would have chocked this up to spam or phishing, but that same family member remembers being gifted .5 bitcoin in 2011 and found a folder on their computer with the transaction number (am I even calling it the right thing? It's an empty folder named with the transaction number)
They don't remember ever opening a wallet, we created a new blockchain wallet as nothing was linked to her email.
Where do i even start?
You don't start, you stop.
This is 100% scam, never click any link(s) from that e-mail. I've heard of it before, it seems it's still active.
Stay safe!
