Maybe we could trade the things under "Valuables" and "Odds and Ends" I'm not really sure what they do, but they could be worth trading for. The only other reason I can see to trade is for items from events. POTCO has said that they will have events, but I am not sure if there will be special items. Because there are only a few different items in comparison to other online games, in the time that you could post that you wanted a ship you could already be halfway to having the gold to buy one.
