Hello everyone, I am Mr. K, and what we are going to talk about today is: "Bitcoin Pizza Day".

I don’t know if you have such a question. As a virtual currency, how did Bitcoin get its price in the first place and prove its “real value”? To answer this question, we have to mention two dates, one is the day when Bitcoin was first priced, and the other is Bitcoin Pizza Day.

In fact, after the birth of Bitcoin in 2009, there was no price for a long time. Because at that time point, the whole society had a lot of doubts about the concept of digital currency. Only a small number of technical geeks, attracted by the concept of Bitcoin, participated in Bitcoin mining.

The day when Bitcoin was given a real price was in January 2010. At that time, on BitcoinTalk, an early Bitcoin forum, a person named "dwdollar" stated that he wanted to create a new market with Bitcoin as a commodity. , where people can freely buy and sell bitcoins. So on March 17, 2010, the first digital currency exchange was born, and the price of Bitcoin was set at $0.003 when it went online. For the first time, Bitcoin had a unified price.

But the price cannot prove the intrinsic value of Bitcoin. What really makes Bitcoin show its payment properties is a social experiment two months later, and this social experiment will have another name in the future, that is, the famous Bitcoin Pizza day.

Time goes back to May 18, 2010, still in the BitcoinTalk forum. At that time, a programmer named Laszlo posted a post saying that he wanted to use Bitcoin to buy pizza. His original words were as follows: “I want 2 large pizzas and I want 10,000 bitcoins in exchange. The pizza can be store bought or homemade. But I need you to deliver the pizza to my door, like a hotel Catering service is the same, I don't need to prepare and buy it myself. I like onions, peppers, sausage and mushrooms, not weird fish pizza"!

It's a pity that this post did not spark a heated discussion, and even 6 hours after it was posted, this post received its first reply. In the next 3 days, people came to watch one after another, but very few people Will ask his address, most of the comments are questioning and ridicule, even he himself has doubts, posting and asking: "No one wants to buy me pizza, is it because the amount of Bitcoin I provide is too low?"

Until 5:17 pm on May 22, 2010, after 4 days of waiting, Laszlo finally posted a successful transaction post. He said: "I just want to tell everyone that I successfully traded 10,000 bits I exchanged two pieces of pizza for coins, thanks jercos”! And attached a photo of the pizza.

This also became the first physical transaction in the history of Bitcoin. Since then, the price of Bitcoin has risen unstoppably. In order to commemorate this day, everyone designated May 22 every year as "Bitcoin Pizza Day".

Although, based on the highest price in Bitcoin history, the price of these two pizzas is as high as 160 million U.S. dollars, which can be said to be the most expensive pizza in history, but it is precisely because of this transaction that Bitcoin has shown its strength. Value, also completed the "peer-to-peer electronic cash system" idealed by Satoshi Nakamoto.
