A college student quickly made over $24,000 just by waving this sign on TV.
Here's the deal: Yesterday on ESPN's "College GameDay" (an ESPN college football show that's filmed at a different college campus each week) some student held the above sign that has both the Bitcoin logo and a QR code.
A QR code is a visual representation of any kind of information (frequently a URL for a website). In this case, the code represented a Bitcoin wallet.
On Reddit, Bitcoin fans managed to enhance the QR code from the screen in order to identify his wallet, so that people could donate money to him.
