You won't get rich doing these things but it's legitimate and you'll get paid in the end. For example, you get a penny for each email you click. You get a penny for a video stream. You can earn dollars for fulfilling offers but those aren't nearly as quick as reading an email. They are upfront in what you get paid so you can decide if it's worth it.
Something very important to note before signing up at any site claiming to pay you cash to take surveys is that all legitimate sites offering online surveys that pay do not charge registration fees – they are free to join. Some sites may even offer you bonus as you sign in, to show you they are happy you have become a part of their team and helping them increase their revenue.
If you're looking to make money by completing surveys online – this site will not be very helpful for you. Like the previous sites, they will take, retain, and sell your information to anyone that waves a dollar in their faces. UNLIKE previous sites reviewed, they hide their consent for that information. It's buried. So not only do you make silly reward points that don't translate to cash but every third party service and product solicitor has your personal information.
