Is There a method to add " Forum Gold"

im looking for an option to add a currency towards the forum.
( being able to buy different things within the forum, like for example private threads, or able to create groups or change user fonts . ( like how administration is Red, Mods are blue, but with currecny they are able to purchase any color they choose.) Being able to buy, sell , trade their services online with this service.

Is this an option?
In read both of these and they look like they are both would be useful for me .

Does it allow users to " Cash Out " as well ? like trade in their forum currency for real money? I didn't see that option or if it's even possible
