I'm selling kinah on Aion NA: - 12b on KT Elyos @13$ each - 20b on DN Asmodian @16$ each 6.0 will come soon, and all the kinah will be untradeable, even among the same account. Think in advance (if you are interested, I'm also selling 2 accounts, with 12 characters, with many items, for only 7$ per character Selling - 2 Aion Accounts in Danaria (NA) (11 alts lv70 + bonus) | PlayerUp Accounts Marketplace. Player 2 Player Secure Platform. )
the kinah on KT Elyos are sold. -20b on DN Asmo still available (and the 2 accounts: they are Asmo as well)
16$ per billion is the lowest price that I found among several websites, but I'll lower it if you want to buy a good amount of kinah. The elyos kinah has been successfully traded, and if you want to lower the risk, we could trade small amount per time. I'm still selling all of my belongings, since I left the game for good (currently I have 32b of kinah available).
