Sounds a lot like the american economy.

I say the amount of Gralat earned is proportional to the amount of gralat you own. If you have 5000 gralats, a diamond's worth a measly 1 gralat ("Well we already have a lot of those, don't hardly need any more. Not that you need the money, mr. fancy-trousers!"), and if you have no gralats it's worth a lot more ("Wow, a diamond eh? Bet it's your first one. Tell you what kid, I'll give you a special deal on this one....")

That way you can't get 10,000 gralats by getting 10 gralats * 1000 diamonds, or whatever the exchange rate is. It'd be 100 gralat for the first one, then since you have 100 gralats you can only get 50 gralats per diamond...

The thing to watch for is guilds that give all their money to one guy, mine as a peasant, and get their money back...so you'd need to make it track how much you've EARNED rather than how much you've got on hand....I mean, you could ditch it all in your house and get rich hoarding it.

Standard response to an economy of this size, you gotta keep the money circulating..."tax" the rich. ^_~
