You guys need some help.
Ok, I'll tell you how to get about 60k to 70k in one shot, but with a few steps.

1. Go to the gaia cash sign if you have it.
2. Do some sponsers that you can do. (if you have a cell phone, that's really good! you can do alot of the deals that way. ^^)
3. Wait for the gaia cash. (Depends on what offer you do, and how much time it takes to get it sent and etc.)
(when you do those offers, you also get a free item that can sold for 4k.)
4. Get up to 99 gaia cash. (this can take some time, or very little time. Again, depends on the offers you do.)
5. When you get 99 gaia cash or up, buy a "Luck Key" from the Cash Shop. (Please, please don't buy the key from the market place!)
6. When you get the key(s), Sell them for 60k - 70k. (Check the marketplace for the current prices.)
7. Wait a bit. (I'd say about 3 to 4 hours at most.)
8. Congratulations if someone bought your key! You just got 60k - 70k!
9. This is optional. Go wild and happy. biggrin

And that's about it. 3nodding
