Best sites to make money without investing?

[Business111]

I know you can't get much by not investing but I would like sites where you can make 20+ dollars a month without investing. Peoplestring.com is an example of that. If you get to have a lot of this sites, you can make something extra for you monthly...PTC sites like Neobux aren't that great... Also, would buying a domain help you in any way example howtoearnonline.com, with that site would u get more ppl to see ur advertising? Thank you

Any affiliate or CPA programs or go to getafreelancer to place your ask if you can freelance. But I think investing in a website and advertising is still required.

Mylot.com is another good site like peoplestring
