The first, real-world transaction using Bitcoins takes place when a Jacksonville, Florida programmer, Laszlo Hanyecz, paid 10,000 bitcoins for two pizzas.

 

The deal came about when Hanyecz posted on the BitcoinTalk Forum that he would give 10,000 bitcoins to anyone who brought him pizza. Someone in the UK took him up on it, ordered two pizzas from Papa John’s in Hanyecz’s area, paid $US25 for them, and got the 10,000 bitcoins in exchange.

 

At the time, Bitcoin was worth approximately 0.003 cents each. So the 10,000 BTC was theoretically worth about US$30.
The deal is legendary with the 22nd of May each year now known as Bitcoin Pizza Day.
