Bitcoin Pizza Day is celebrated annually on May 22, honoring the world's first documented real transaction using bitcoin. In 2010, programmer Laszlo Hanyecz paid 10,000 BTC for two pizzas at a Papa John’s pizzeria in Florida, USA. At that time, 10,000 BTC was worth approximately $41, but today that amount is equivalent to hundreds of millions of dollars, highlighting the incredible growth in the value of bitcoin.

Hanyecz's transaction became a landmark event that demonstrated the potential of bitcoin as a medium of exchange, rather than just a speculative asset. It took place through the BitcoinTalk forum, where Hanyecz offered to pay for pizza with bitcoins, and a user named Jeremy Sturdivant accepted the offer, ordering the pizza for him.

Bitcoin Pizza Day symbolizes the evolution of cryptocurrencies and their path to mass adoption. Each year, the crypto community celebrates this day by sharing stories, conducting promotions, and advocating for the use of cryptocurrencies. The event serves as a reminder of the importance of innovation and belief in new technologies that are transforming the financial world.
