"I like having leftover pizza to nibble on later. You can make the pizza yourself and bring it to my house or order it for me from a delivery place, but what I'm aiming for is getting food delivered in exchange for bitcoins where I don't have to order or prepare it myself, kind of like ordering a 'breakfast platter' at a hotel or something, they just bring you something to eat and you're happy!"
Another forum user took him up on the offer, and a deal was struck: 10,000 bitcoins were sent in exchange for two Papa John's pizzas.
Since then, the price of bitcoin has skyrocketed, meaning the value of those two humble pizzas has increased astronomically.
How much would they be worth now? Over $108 million.
May 22 has been named Bitcoin Pizza Day in the cryptocurrency community. While the item purchased was relatively insignificant, the transaction itself was marked as revolutionary. With it, the era of bitcoin truly began.

Bitcoin has been down close to 40 per cent since the beginning of the year, but a Wall Street Journal report has found companies are paying as much as $US1 million in signing bonuses to secure crypto talent.
At the same time, jobs advertised on LinkedIn with the terms "blockchain", "bitcoin" or "cryptocurrency" have jumped 151 per cent from the start of this year to mid-May compared to the total of 2017.
