May 22 marks the annual “Bitcoin Pizza Day,” anniversary of the day in which one of the most expensive pizzas in the history of the world was purchased.

The Story

Laszlo Hanyecz purchased the so-called Bitcoin Pizza on 22 May 2010. The programmer paid a Bitcoin Talk forum user 10,000 BTC for two Papa John’s pizzas.

The value at the time of the bitcoins was approximately $25. When based on today’s exchange rate, that value skyrockets to $2,330,000. Here is the original post on the Bitcoin Talk forum:

Here is confirmation of the exchange, which is considered by many the first Bitcoin transaction.

As Bitcoin climbed to its record price of nearly $1,200 in December 2013, the value of the pizza was approximately $11.47 million.

This transaction is considered the very first transaction in the Bitcoin world, with May 22 celebrated as ‘Bitcoin Pizza Day.’

“It wasn’t like bitcoins had any value back then, so the idea of trading them for a pizza was incredibly cool,” Hanyecz said in a 2013 interview with The New York Times. “No one knew it was going to get so big.”

This year, the tradition of celebrating May 22 as Bitcoin Pizza Day continues, with an Albany, New York Papa John’s location delivering pizza slices to children at the Bernard & Millie Duker Children’s Hospital.

The Hospital is a facility devoted exclusively to the medical needs of infants, children and adolescents, and is the referral center for all seriously ill and injured children for 25 counties in upstate New York and western New England.

Individuals can buy a slice of pizza for the kids at the Children’s Hospital via BitPay.

Each slice costs $1.50 and will be delivered on Friday, May 22nd. If more pizza than needed is purchased, then it will be delivered to the hospital in intervals.

That won’t be the only way to buy pizza for bitcoins, as Pizza for Coins specializes in just that.
