The origin of Bitcoin Pizza happened on May 22, 2010, when Laszlo Hanyecz, a programmer, paid 10,000 Bitcoin to an online forum user to buy two Papa John's pizzas. This was one of the first real-world Bitcoin transactions. At that time, the value of 10,000 Bitcoin was only about $25, but now it is worth millions of dollars! This transaction has become an important symbol in the history of Bitcoin and is often commemorated as "Bitcoin Pizza Day".
