You make Kinah in Aion 2 from quests and dungeons while you level, then from selling drops, materials and crafts on your server's Auction House (the Market in-game) once you're at the cap. NC's paid Membership unlocks the Auction House, and NC says you need an active one to trade there.
The in-game name is Kina (Kinah in the original Aion, and on most shops). NC hasn't published Kinah payouts for the global servers yet. Where this guide mentions numbers or limits, they come from the Korean and Taiwanese versions and may change here.
While you level, Kinah comes to you. Follow the main story, clear side quests and sealed dungeons in each zone, and sell what you don't use.
NC's Membership unlocks the Auction House and the official Kina and Quna exchange. Without it you can still earn Kinah, but NC says an active Membership is required to trade on the Market.
Quna is the premium currency you buy with real money. Through the exchange, members can swap it for Kinah, which makes it NC's own way to buy Kinah. In Korea the rate moves with supply and demand; NC hasn't published how it works here.
