On May 22, 2010, Hanyecz traded 10,000 Bitcoin for some pizza in what is widely believed to be the first real-world transaction involving Bitcoin. Each year, on May 22, Bitcoin enthusiasts all over the world celebrate “Bitcoin Pizza Day” to mark the event. Bitcoin then was worth less than a penny.

Source - At the end of a volatile week in the stock market, “60 Minutes” examines the even wilder financial world of Bitcoin and other cryptocurrencies. The story, reported by Anderson Cooper, includes the first television interview with the legendary “Bitcoin pizza guy,” Laszlo Hanyecz.

Hanyecz, a computer programmer who lives in Florida, told Cooper he made a number of other trades after the pizza. In all, he estimated that he spent 100,000 Bitcoin on a number of items, much of it on pizza. At the time of this interview, one Bitcoin was worth about $8,000.

“That’s $800 million,” Cooper says. “You spent about $800 million on pizza?”

Hanyecz replies, “Well, if you look at today’s exchange rate.”

People talk a lot about what their worst nightmare would be. For me, it’s this: sitting in a room across from the heir to the Vanderbilt fortune as he laughs in your face for losing a billion dollars on pizza. I get that Anderson had to get the sound bite so he had to ask the question, but to laugh in his face is diabolical. I don’t think anyone would’ve blamed Laszlo Hanyecz if he had jumped across the room and tried to strangle him to death.

Then he keeps going…

“Are there nights you wake up,” Cooper asks, “where you think, ‘I could have had $800 million… if I hadn’t bought those pizzas?'” “I think thinking like that is… not really good for me,” Hanyecz says.

Yes, Anderson, there are nights when he thinks about it. It’s every night. Not one second of one day goes by where he doesn’t think about those fucking pizzas. How if he had just sucked it up and ate a can of tuna instead of a Domino’s flatbread, the next seven generations of Hanyecz kids would be set for life. Those pizzas define his entire existence. If I were him I’d have been institutionalized already. Poor guy. The lights are on but no one’s home.

I’m sure his family hates his guts too. The good news is Bitcoin is all over the place so maybe he can still buy in and make a buck. It just won’t be $800,000,000.
