Max gold expansion

[WarpedPerspectiv]

Sorry if this doesn't belong here, but wasn't able to find anywhere else to either ask this question or the answer for it. So what do I need to do so I can expand how much gold I have? Currently at the around 500 gold max and don't have anything I can spend it on, as well as no visible way to expand the limit.
