The first known physical item purchased with Bitcoin is known as a “Bitcoin Pizza.”
The only Bitcoin forum that was available at the time was Bitcointalk, where a programmer by the name of Laszlo Hanyecz posted on May 22nd, 2010. The value of 10,000 BTC at the time was about 41 USD. This comes out to around 0.0041 USD per bitcoin. Another Bitcointalk user accepted Hanyecz’s offer, paying 25 USD for the two pizzas and making a staggering 16 USD profit even at the time.
