Pizza Day! On 22 May 2010, Laszlo Hanyecz wanted to prove that Bitcoin could be used as a means of payment by purchasing two pizzas for 10,000 Bitcoins. Two pizzas worth $25 became the initial value anchor for Bitcoin.
Back then, 1BTC = $0.0025. Today, 1BTC = $70,000. Fourteen years and 28 million times.
