Bitcoin Pizza Day!
Exactly 14 years ago, programmer Laszlo Heinitz bought two Papa John's pizzas for 10,000 BTC.
On the BitcoinTalk forum he asked to exchange 10k bitcoins for two pizzas. People offered him to just sell all the bitcoins (41$ at that time) and just order a pizza, but he refused such an offer.
And on May 22, 2010, 4 days after he published the post on the forum, he reported that he managed to exchange bitcoins for 2 pizzas.
Now 10,000 BTC is worth about $700 million, 8,971 kilograms of gold or 683 tons of silver.
