well the discussion actually started on another ideas and suggestions topic tittled "currency" when a guy had this to say.
(("My apologies if this is already a thing, but I would like to propose there being a finite limit to the amount of currency in circulation and not an unlimited amount that can be created from player sold items/vehicles/etc.
The reason: what breaks most mmo economies is the ability for players to amass wealth without limit, which ultimately causes the currency to be essentially worthless. You can look on the market of nearly any current mmo and see items priced in the millions+ because the majority of players have more currency than they could ever possibly spend. Most mmo's have attempted to compensate for this inevitability by having 'money sinks' or regularly introducing new currencies to keep the market from flooding and prices skyrocketing to absurd levels. However, money sinks and new currencies always fail since they underestimate the speed at which players can amass currency (especially when working together in large numbers). I would like to see a mmo do the right thing and learn from the mistakes of the thousands of mmo's that have failed at this in the past, and the solution is simple: cap the currency."))
Alot of people tossed around crazy theories, solutions and assumptions and i just thought why not this crazy idea lol
