i'm pretty sure full KYC-ed legal names have been pilfered from bittrex, which are used to generate scam e-mails with a bit of verisimilitude.
if you click the link, a site comes up which will smoothly connect to a crypto wallet and ask it to sign a message presented only as a bunch of hex. i, um, chose not to.
not many crypto enthusiasts on my mastodon timeline, but if you ever had a bittrex account, be careful out there. https://www.reddit.com/r/Bittrex/comments/17qaf36/is_this_email_a_scam_picture_below/
