Bitcoin Pizza Day, celebrated on May 22, marks the first real-world transaction using Bitcoin. In 2010, programmer Laszlo Hanyecz paid 10,000 BTC for two pizzas, proving Bitcoin could be used as a medium of exchange. At the time, the coins were worth about $41—today, they'd be worth millions. This historic moment symbolizes Bitcoin’s evolution from an experimental digital currency to a global financial asset. It highlights the power of decentralized systems and how early adopters shaped the crypto space. Bitcoin Pizza Day serves as a reminder of how far the technology has come and the potential it still holds.
