There are five resources in the game. You can collect them through space adventures, exploration, and trading at planetary markets.

Resources

Resource Base Price Storage per Unit Notes
Satoshi 1 0 The universal currency. Takes no cargo space
Gold 1,750 2 Premium resource, needed for high-tier upgrades
Scraps 40 10 Common crafting material, used heavily in upgrades
Fuel 30 0 (tank) Stored in the spaceship's fuel tank, not the cargo hold
Rum 100 1 Boosts morale, required for teleportation and some upgrades

Trading at the Market

Every planet has a market where you can buy and sell resources. Prices fluctuate based on supply and demand at each planet, so the same resource can cost different amounts on different planets. Scarcity bites hard: a resource a planet is nearly out of gets expensive fast, while a well-stocked planet sells it cheap.

Asteroids have no market of their own. To trade out among the asteroids, build a Space Cove with the Market building. Cove markets work like planetary ones but take a noticeably fatter cut between buy and sell prices - convenient, not cheap.
