Apart from helping you earn more per survey completed, a high trait score will also make it possible for you to receive the maximum number of surveys available. One other way you can earn from Paid Viewpoints is through referrals. You get paid 20% of whatever your referrals earn from completing “biz surveys” (that is, excluding what they earn from trait surveys or their own referrals).
I belong to almost all of the sites you listed and out of all the surveys I take I don’t qualify for 95% of them. I will spend 15 minutes with generic questions with them collecting information about me then when done they say I’m not eligible for the survey or they have reached the required amount of people for that research. I can understand the reaching the required amount of people but I would think I would qualify for at least 1 or 2. It’s really discouraging when you take all that time to do the survey and not even get any points for doing so!
You don't get any money until you've saved up to $30 in credit. I don't qualify for most surveys I try to do. Lottery scratch points tease $10, $25, or even the chance to win $100, but all I've ever won is a few cents. I wonder if it even is possible to win any dollar amount or if that's just a lie. At most I earn several cents a day. Definitely not worth the time.
In my opinion, Inbox Dollars is a scam. After registering and wasting hours upon hours to make a few cents I started receiving a swarm of emails, 83 in one day to be exact, from the companies I was questioned about in the surveys. Not to mention an abundance of calls from unknown numbers. What an invasion of privacy! This is not worth the hassle. Be smart and don’t fall for this one!
