I looked at the forums earlier, and saw that someone wanted the option to throw away gold. Why not just be able to turn gold into crowns? Like, 1000 gold could be 10 crowns or something.
Because gold costs nothing. It's free and everywhere in the Spiral. Most players have to throw away gold just to keep their backpacks from filling up. You can earn 100 free crowns a day already by playing trivia. 1000 gold for 10 crowns would allow me to earn about 4000-8000 free crowns every day. KI cannot make money by giving away it's only form of money for free. The reasons are clear why this will never happen, there would be no game if they did do it. That aside, KI has already stated multiple times that crowns will never be available for gold, period.
