Bitcoin Pizza Day is celebrated every year on May 22nd. It marks the first known real-world transaction using Bitcoin. On May 22, 2010, a programmer named Laszlo Hanyecz paid 10,000 Bitcoins for two pizzas from Papa John's.
At that time, Bitcoin was nearly worthless, and the transaction was mostly a fun experiment. But today, those 10,000 Bitcoins would be worth millions of dollars, making it one of the most expensive pizzas in history.
Bitcoin Pizza Day has become a symbolic event in the crypto community, reminding people how far Bitcoin has come and how quickly its value has grown. Many crypto enthusiasts celebrate the day by buying or eating pizza and sharing stories or memes about the famous transaction.
