While on air, Miller surprised Bloomberg anchors Adam Johnson and Trish Regan each with $20 worth of Bitcoin.

But as Johnson received the paper gift, he briefly exposed the QR code (see above). This act was effectively like sharing a bank account and PIN number.

Immediately, someone lifted the QR code and stole the $20.

This morning, Miller reported that he had engaged the thief — someone who goes by "milkywaymasta" — on Reddit.
