Bitcoin unfortunately makes this feat very difficult to verify. We will never truly know how much of that $24,000 the poster controlled in the first place.
1) Have 5+ BTC 2) Recognize a QR code on a TV broadcast 3) Think to pause the tv broadcast, decode the QR code and send BTC 4) Completely unaware of the 1000s of news articles and broadcasts about the soaring value of BTC
Maybe he sent it to himself, maybe someone else was just very generous, but no one purposefully sent 5BTC without knowing it was valuable.
