Bitcoin Pizza Day is celebrated every year on May 22nd to commemorate the first transaction in history where Bitcoin was used as a currency.
On May 18, 2010, programmer Laszlo Hanyecz from Florida posted on the Bitpointalk.org forum expressing his desire to buy two large pizzas for 10,000 Bitcoins. On May 22, a British man accepted his offer and purchased the two pizzas for him, at a time when 10,000 Bitcoins were valued at approximately $41. With the continuous surge in Bitcoin's value, by 2024, based on a trading price of about $71,000 for Bitcoin, those two pizzas could be worth as much as $710 million.
Today, on this day each year, the cryptocurrency community gathers to celebrate. Some people buy pizzas with Bitcoin to commemorate this special day. Additionally, some merchants and businesses offer special promotional activities, such as discounts for Bitcoin payments or holding lectures and seminars related to Bitcoin. Bitcoin Pizza Day symbolizes the transition of Bitcoin from theory to practice, showcasing its practicality and feasibility, and also reflects the development and changes in the cryptocurrency market.
