Do not spend Antimatter on refueling your reactor. Simply wait fifteen minutes and it will gain an energy charge. Additionally, spending Antimatter to refresh the shop's inventory also is a waste of resources. Save your Antimatter to speed up the forging process and obtaining new crew members and starships.

Complete bounties to earn Antimatter. Most of them must be completed in order to progress through the game. Note: The daily bounties have a gold reward instead of Antimatter, but they are still worthwhile to complete.
