How to get ingame Money?

Hello guys,can you tell me,what's the best way to get gold on 20-30 level?

Farm cloth and sell on ah :)

Best way is to not be level 20-30. Xp is 5x rates, get your *** to 58 and the gold will roll in. I got my mount at 58, didn't buy most of my spells until 65, at 70 I almost had the 630g needed for the 100% mount. Just level up and dont worry about gold, just dont buy your spells.

There is no best way, there are multiple ways, you should look them up on google and pick the one that best suits you.

Thank You.
