Help with dead frontier!?

well if your lvl 11 by now most players leave at lvl 8. What i do is collect items and sell them on the marketplace so i have a little bit of cash before i leave. the marketplace is usually selling at unrealistic prices. The best way to make money is to invite your friends to play and have them get to lvl 10. once they do it will gie you about $4000 i think.
