There are two ways to make money essentially: Hunt and Craft.
It's a matter of what you hunt to gain coin. You can gain coin from two ways hunting: looted and sellables. What you get in loot is either coin directly (by means of the little coin jingle or by means of wallets, bags of coins, etc.) or indirectly (refurbished items, components, resources, etc. that can be sold at a pawnbroker). On the craft side, you can either sell items at the pawnbroker for quick cash, make items for another player directly and request a particular value you set, or sell on the consigner for a value you set and hope it's bought.
