According to Dan Held, on May 22, 2010, Hanyecz Laszlo made the first ever Bitcoin transaction by purchasing two Papa Johns pizzas for 10,000 BTC, a sum now valued at $1.2 billion. This historic event, known as Bitcoin Pizza Day, underscores the exponential appreciation of Bitcoin and emphasizes the long-term value of holding BTC (HODLing). For traders, this milestone serves as a powerful reminder of Bitcoin’s potential for dramatic price appreciation and the importance of patience in crypto investment strategies (source: Dan Held on Twitter).
