Did you know that the first real-world transaction using Bitcoin was for a pizza? On May 22, 2010, a programmer named Laszlo Hanyecz paid 10,000 Bitcoins for two pizzas. At that time, those Bitcoins were worth about $25, but today, that amount would be worth millions! This day is now celebrated as "Bitcoin Pizza Day" in the crypto community. It's a fun reminder of how far cryptocurrencies have come!
