I used to invest my money in those HYIP sites and money cycler sites, but it's not risk-free, and I ended up losing money more than than earning or making profit from it. So newbies should not really try it because they may end up being scammed, because they are all Ponzi schemes. So now I just concentrate on writing articles and on other task-oriented sites, but I'm currently looking at how to earn passive money from those pay per download sites.
