I replied to these e-mails but my replies were ignored like they have not been read and I was responded with the same reply, keeping asking me about my bank details. Are these e-mails legit? What's this all about?
Have you checked the headers? Actually, I get similar mails claiming to come from Spondoolies, KnC, Bitmine, Bitmain and some other companies. It seems as someone got a whole bunch of email-adresses from people in the Bitcoin-world. Has the mail an attachement? All the mails I received had a jar attached... guess what it was....
