When people first started delving into the world of cryptocurrency over a decade ago, they were probably delighted to see their investments increasing in value.
But while many sat on their coins in the hope they would continue building, Laszlo Hanyecz was eager to make his first 'real world' purchase - two pizzas from Papa John's.
So in 2010, the computer programmer used 10,000 Bitcoin for the grub, worth around £30 at the time. Fast forward 11 years and they're worth £270 million ($380m).
Anyone else feel sick for him?
Well don't, because according to Laszlo - who is from Florida - he's not lost any sleep over the impulse purchase. They must have been really good pizzas then.
Speaking to Coin Telegraph a few years back, he said: "I don't regret it. I think that it's great that I got to be part of the early history of Bitcoin in that way.
"People know about the pizza...everybody can kind of relate to that and be [like] 'Oh my God, you spent all of that money!'"
He added: "I didn't think it would get as popular as it has, but it's gotten to be a really catchy story for people."
When it came to being able to spend the Bitcoin, Laszlo exchanged it with an 18-year-old in a Bitcoin forum.
That 18-year-old was Elon Musk. Jokes... but imagine.
So, back on 22 May 2010, Laszlo wrote on Bitcointalk: "I'll pay 10,000 Bitcoins for a couple of pizzas.. like maybe 2 large ones so I have some left over for the next day.
"I like things like onions, peppers, sausage, mushrooms, tomatoes, pepperoni, etc.. just standard stuff no weird fish topping or anything like that.
"If you're interested please let me know and we can work out a deal."
After he's completed the transaction, he even posted a thank you to student Jeremy Sturdivant, (jercos), writing: "I just want to report that I successfully traded 10,000 bitcoins for pizza. Thanks jercos!"
Bet Jeremy's living the life of Riley now.
Bitcoin Who's Who reached out to Jercos at his California home to get some answers.
Sturdivant revealed he quickly spent the 10,000 bitcoin transferred to him by Laszlo when it was worth around $400 (£280).
One stand out moment from the interview was when Jercos said: "Give a man a pizza, he'll eat for a day, let him buy pizza with bitcoin, revolutionize the economy."
