On May 22, 2010, programmer Laszlo Hanyecz made history by completing the first commercial transaction with Bitcoin: he paid 10,000 BTC for two pizzas from Papa John’s. At the time, the amount was equivalent to about US$$ 41. Today, that amount exceeds US$$ 600 million, making these the most expensive pizzas ever purchased. This transaction marked a turning point for Bitcoin, demonstrating its potential as a means of payment in the real world. Since then, "Bitcoin Pizza Day" is celebrated annually on May 22 by cryptocurrency enthusiasts around the world. Events, promotions, and meetups are organized to commemorate this historic moment. In Brazil, the date has gained prominence, with various cities promoting activities to celebrate. Companies like Mercado Bitcoin and Rappi have already conducted special actions, such as pizza deliveries and BTC rewards for their customers. Bitcoin Pizza Day is not only a celebration of an unusual purchase but also a reminder of how much Bitcoin has evolved since its early days. It is an opportunity to reflect on the journey of cryptocurrencies and their growing impact on the global economy.
