How old is Bitcoin?
In 2008 the first whitepaper describing Bitcoin was published, with the protocol going live in 2009.
In May 2010, Laszlo Hanyecz was the first person to complete a Bitcoin transaction. He purchased two pizzas for 10,000 BTC, an investment that would be worth approximately US$542,874,000 today. This momentous occasion is known as Bitcoin Pizza Day, celebrated annually by Bitcoin enthusiasts.
