My idea
Hello, i checked the site what you mentioned before. That kind of site is pretty good, i mean it's definetly brings money, but to build it, host it, is really much work, and also needs huge money to invest. As i searched for options to earn money online, i realized one of the best solution is to have a website where you can show other people how to earn money. Yes it's sounds dumb, and impossible at first, but think about it. If you own a site (for example a wordpress site) you have to share something which can bring visitors to your site. Most of the people want to earn money easily, and why don't you be the one who show them online options to earn money. There are many adclick site (you get money after click to adverts), or sites which pay money after you take a survey, in your site (with my help) you can make a collection about these sites. This have a really big adventage in SEO, because you build a link system, and i bet this kind of site would be famous.
