In the year 2050, the world's economy collapsed due to a global shortage of cat videos. As society crumbled, a group of rebels realized that the real value was not in money, but in the most comfortable socks.
Now, a single pair of high-quality, hand-knitted socks can buy a decent meal, a night's stay in a hostel, or even a used car.
The Sock Exchange Rate Index (SXI) is the standard measure of sock value. Currently, a 6-pack of novelty socks is equivalent to 1 Bitcoin, while a single, rare, signed limited-edition sneaker sock can buy you a private island.
