On May 22, 2010, American software engineer Laszlo Hanyecz exchanged 10,000 Bitcoins for 2 pizzas, becoming the first physical transaction in Bitcoin history. This transaction later became known as "Bitcoin Pizza Day," symbolizing a turning point in the practical application of Bitcoin. To this day, 10,000 Bitcoins are worth an astonishing amount, but more importantly, it proved the commercial potential and market acceptance of virtual currencies, paving the way for the practicality of cryptocurrencies.
