First allow players to trade items without a token with the following restriction: Once an item is traded it cannot be sold to a vendor or placed on the Auction house.
Second create and sell lots of different cosmetic items in the cash shop that can be traded or sold on the AH. This and not tokens should be your primary money generator.
Remove all restrictions on the AH. Think of it in terms of Guild Wars 2 they don’t have any restrictions on their AH and yet you don’t see a single bot on any GW2 server. The 30% fee for not token users can still remain.
Finally allow players to purchase TP directly from the cash shop using Silver and allow players to purchase Silver using TP.
If you do this then you will get all of the money and the gold sellers will for the most part move on to other games.
