What will be the best earning site nowadays?

My luck has been with uniquerewards.com, quickrewards.net, and treasuretrooper.com. I have received payment from all at least 3 times in the last year. Everything was as expected. I think you just have to try them out and never upgrade until having received payment. Everyone's opinions are so different for each site that I never trust other people, I just have to find out myself. Good luck to you in your search.
