This is a rather interesting idea, and would improve the rather "simple" runescape economy, but to have the currency fluctuating so wildy as to gain/lose 100 mill in a day, well. . . I'm one of the many people that can only get on RS on weekends, so this vast economy would only be a hindrance. Since by the time I'd be able to get back on, who knows what kind of shape me finances might be in. As several have said before, there would be no point to leveling skills, only investing. As I play for the point of getting better, and talking to people, this would most likely drive me away, for I've no patience for carefully watching values. Just a thought.
