I think you could find some new and good sites to join. You should check the site yourself and do by yourself. The first time for me to invest is when I have only 1$, then through invest, I earn till 5$ in a week but then my egold was stolen so now I also need to earn the first 1$.
Yeap if you have $1 just keep it. Work your way to hyip by posting in paid to post forum. And when you have around $5, then you start to invest in hyip or autosurf.
With 1$ you won't make too much money, keep them and post in this forum so you'll make 4-5$ then join a very good autosurf and you'll have a profit of 120% on the first month!
