Bitcoin Pizza Day is celebrated on May 22 each year to mark the first known commercial transaction using Bitcoin. On this day in 2010, a programmer named Laszlo Hanyecz made headlines by purchasing two pizzas for 10,000 BTC.

At the time, Bitcoin was still a new and relatively obscure digital currency, and this transaction highlighted its potential use for everyday purchases. The pizzas were bought from a local pizzeria in Florida, and the purchase was notable not just for the price but for the idea that something as common as food could be acquired using Bitcoin.

Over the years, the value of Bitcoin skyrocketed, making those pizzas worth millions of dollars today. Bitcoin Pizza Day serves as a reminder of how far the technology has come and is often celebrated with pizza parties, IT forums, and discussions among enthusiasts. It reflects both the evolution of digital currencies and the importance of practical use cases within the broader financial landscape.
