Though many games these days let you handle all sorts of money, Crimson Desert is rare in the sense that it allows you to learn about investment banking and start putting stuff on the market in the hopes you'll get some good returns.
While index funds aren't directly available, players can invest gold bars, or, if they do not like to wait, sell them to the proper vendor for massive instant cash (500 silver a piece), making this item one of the most valuable in the entire game.
