The Bitcoin Pizza Day on May 22, 2010, is a highly iconic annual anniversary in the cryptocurrency realm, celebrated by the global crypto community every year. Its commemorative significance stems from the groundbreaking first physical transaction in Bitcoin's development history. On May 22, 2010, programmer Laszlo Hanyecz from Florida, USA, posted a trade request on the Bitcoin forum, offering 10,000 Bitcoins for two pizzas. At that time, a user named Jeremy Sturdivant responded to the offer by ordering two pizzas worth about $25 via credit card and having them delivered to Hanyecz's residence. This seemingly ordinary transaction was, in fact, extraordinary; it not only marked the first successful application of Bitcoin for purchasing a physical product but also became a pivotal turning point in the transition of cryptocurrency from a conceptual idea to practical application, leaving a significant mark in the development history of digital currency.
