An excerpt from my faq(will be posted here soon).
Money
1. Money. Ok, this is the fun part. You are broke. You know that 60g you have total? That's nothing. Once you get to level 4 or so, you should have atleast a 12 stack of the same type of crystals. Check the auction house for pricing. Look at what the previous bids were, THEN go to the sell, and sell a 12 stack for whatever the lowest price was. On my server, it was 1000 gold. Why the lowest amount? You are broke. Your priority is to sell the stack as soon as possible. If you have one of a crystal, put it up for 100 gold. Yeah, the minimum people seem to sell things is 100 gold. Once you get your hand on some money, buy a better weapon at least. Or spell. Make sure you are of a high enough level to cast the spell, of course. By the way, it's in the auction house for a week, or until someone buys it.
2. Fishing. After depleting the fish's stamina by pushing in the opposite direction of the pole, push enter to reel it in. Yeah, it doesn't say that ANYWHERE. If you don't reel in a fish, you don't lose the bait. That includes fishing up kelp and worthless stuff. Save the kelp up to sell. It's used in cooking(high cooking). It IS a good way to get a bit of money for the first couple levels.
3. Things are expensive. Make sure to always sell stacks on the auction house first. If they don't sell there, THEN sell them to a vendor.
This was mostly for the first couple levels of the game. Use a wind crystal and a yagudo necklace to make thread. Sell the thread in stacks. The yagudo feathers sell very fast as well.
Farm crystals. I'm not kidding, farming the crystals will get you the money you need. I know that when you start your professions, you will need crystals as well, but at that time, you will be a lot stronger. You will be able to kill things faster, and get crystals faster.
