On May 22, 2010, programmer Laszlo Hanyecz made the first real-world Bitcoin transaction by buying two Papa John's pizzas for 10,000 BTC. At the time, this was worth roughly $41, intended as a fun test of using digital currency for goods. Today, those same 10,000 Bitcoin are worth hundreds of millions, marking the ultimate "what if" story in crypto history. It is now known as Bitcoin Pizza Day, celebrating the shift from a digital experiment to a global, high-value asset.
