#BinancePizza is a celebration of Bitcoin Pizza Day, which marks the first real-world Bitcoin transaction on May 22, 2010, when two pizzas were bought for 10,000 BTC. Binance honors this milestone with global events, giveaways, and community activities like pizza-making contests and crypto rewards. It highlights how far crypto has come—from a novelty to a global financial movement—while uniting the community in a fun and nostalgic way.
