The Binance Pizza Day on May 22 is an annual celebration to commemorate an important moment in cryptocurrency history—the first real-world purchase made with Bitcoin. On this day in 2010, a programmer named Laszlo Hanyecz bought two pizzas for 10,000 bitcoins, marking the first time Bitcoin was used to purchase a tangible good. This event symbolizes the beginning of cryptocurrency's journey from a digital concept to a practical means of payment.
