#BinancePizza Binance Pizza Day is a celebration organized by Binance, the world’s largest cryptocurrency exchange, to commemorate one of the most iconic moments in crypto history—Bitcoin Pizza Day. This event marks May 22, 2010, when a programmer named Laszlo Hanyecz made the first known purchase using Bitcoin: two pizzas for 10,000 BTC. At the time, those bitcoins were worth about $41; today, they would be worth millions.
