Bitcoin Pizza Day is celebrated every year on May 22nd to commemorate the first known real-world transaction using Bitcoin.
Here's what happened:
On May 22, 2010, a programmer named Laszlo Hanyecz paid 10,000 Bitcoins for two Papa John’s pizzas.
At the time, 10,000 BTC was worth around $41 USD.
He posted on a Bitcoin forum offering the coins to anyone who would order and deliver pizza to him.
A British man accepted the offer and had the pizzas delivered to Laszlo in Florida.
Why it's significant:
It marked the first tangible use of Bitcoin as a currency for a real-world purchase.
It demonstrated Bitcoin's potential as a medium of exchange, rather than just a theoretical digital asset.
At today’s prices (as of 2025), those 10,000 BTC would be worth hundreds of millions of dollars — making it perhaps the most expensive pizza in history.
