#BinancePizza American Laszlo Hanyecz, a programmer from Florida, bought two Papa John's pizzas for 10,000 BTC. He posted on the Bitcointalk forum and offered bitcoins to anyone who would order him pizza. One of the users agreed and fulfilled the order.

This is the first real transaction using bitcoin that demonstrated that cryptocurrency can be used as a medium of exchange.

10,000 BTC at the time of purchase was worth about $41. Now it’s worth hundreds of millions of dollars.
