Well, let's assume bandos chestplates are crashing, and are trading at a street value of cash for mint + BCP. Consider this: You buy a mint from a RWT site. You buy a BCP for minimum, instantly on the grand exchange (-23.8m) You sell a BCP for med, with a mint (25.1m) You made a profit of 1.3m. If historical rates apply (adjusted for inflation), you would probably pay about 2.50 USD for 1m, or 3.25 USD for a mint. A gold farmer could gold farm about 800k an hour playing gnome restaurant one one account, and take the mints (about one every ninety minutes) to sell to more players. 800k + 866k = 1.66m per hour, or about $4 an hour, which is a lot better than what standard wages in developing nations are. I'd say the risk for mint RWTing is very likely, if it's not already ocurring.
