This is actually the first time i've seen this.
Have you recently signed up to any dodgy sites?
I think it has something to do with the bitcoin websites I've made, my email address was in the public whois. In another scam email the guy mentions one of my bitcoin domains..
Never received any crypto related scam - phishing emails, beginning to feel a bit left out now
Might be because I only use throw-away email accounts....really hope nobody was gullible enough to send any btc.
Looks like the guy already scammed a few people :/
