Credit - Reldeam/Idle-Inc GitHub Wiki
Overview
Credit is the currency of the Idle Inc. universe. Credit is used to buy almost everything. Facilities require credit to be build, some upgrades technologies require credit, it can be exchanged for resources or deeds on the Universal Exchange (UE), and it can be used to purchase unclaimed deeds.
A player begins with a small amount of credit, just enough to build their first facility. After that a player can earn credit by selling resources and deeds on the UE.
Inflation Management
Idle Inc. maintains a constant ratio or resources to credit in circulation. This is done by Idle Inc. purchasing resources on the UE when more resources enter circulation (only resources that are offered at or above the mean market value will be purchased in this way). A fee on all UE offers ensures constant deflation of credit value when resources are not being purchased by Idle Inc.
This method is in place to ensure the value of credit remains steady over time.
