I am getting to a point where my gold is well over 25 million. I know there are others who have billions of gold and nothing to do with it. Sooo, I was thinking...perhaps adding in options to upgrade the basic habitats with coins instead of gold? But make it like, super high on coins, that way the exchange is more fair. I am not very good at math, so crunching numbers isn't my forte, but something like that would help get rid of coin for those with insane amounts. I do apologize if I am not very clear, as my meds make me loopy, lol.
