Bitcoin Pizza Day, celebrated annually on May 22nd, commemorates the first documented real-world Bitcoin transaction in 2010 when programmer Laszlo Hanyecz purchased two pizzas for 10,000 Bitcoin. At the time, this amounted to approximately $41, but with Bitcoin's exponential increase in value over the years, those same bitcoins would be worth hundreds of millions, if not billions, of dollars today. Despite the hindsight of the transaction's staggering value, Bitcoin Pizza Day serves as a reminder of Bitcoin's journey from a niche technology to a global phenomenon, showcasing its real-world applicability and potential as a transformative force in finance and technology.
