There are a lot of ways to get some Coins in New World. And completing quests is one of the most common! Main Quests, Side Quests, Faction Tasks, and Town projects will help you to earn some money. A secondary way that lets you make bigger money is just farming mobs, looting, and selling gear that you don't need. If you want the big deal and become really rich, you should try to gather different resources and sell them in settlements with high prices on them. And the last way is the hardest one - it's all about crafting gear for sale, which can be very expensive! But you have to level up your crafting skills to be able to make good equipment.
