Bitcoin Pizza Day is almost here. May 22 marks the 16th anniversary of Laszlo Hanyecz buying two pizzas for 10,000 BTC. At today's price of $81,135 per coin, those two pizzas cost $811 million. It is the most expensive meal in financial history -- and also the proof of concept that started everything. Without Laszlo making that trade, Bitcoin might have stayed a theoretical concept. The first real-world transaction gave it gravity. OKX is celebrating Pizza Day this year, and the timing is fitting. The exchange now lets users trade stocks alongside crypto -- a full circle moment from 'can Bitcoin buy pizza' to 'can your crypto exchange replace your brokerage.' The ecosystem that started with a novelty pizza purchase now handles trillions in daily volume, institutional ETFs, and cross-border settlements between JPMorgan, Mastercard, and Ripple. Not bad for 16 years. The Pizza Day tradition is also a reminder of what makes crypto different from every other financial innovation: its origin story is public, permanent, and verifiable on-chain. Block 57,043. Laszlo's wallet. The transaction is still there for anyone to check -- no institution or regulator can rewrite it. That is the point. How much BTC would you have held onto if you were Laszlo -- or would you have made the same trade? #OKXPizzaDay
