I don’t see PaidViewpoint on your list. I like using that site. I signed up for it on June 28, 2016, but I guess I forgot about the site and stopped using it on July 24, 2016 but had a total of $1.91. I started using it again on May 5, 2018, and I’m now up to $27.05 and have a trait score of 10, which is the highest. The surveys are easy and you don’t get disqualified. I mostly earn 10 cents, but once in awhile I earn some good money like 62 cents. It does take awhile to add up, but it’s free money.
As well as filling in the familiar surveys, you can sign up to complete free and paid offers, which is how many users say they make the bulk of their CashCrate money. In these cases companies will pay you to sign up to their website, or to try out the service they offer, such as a financial credit check. These are often quick, straightforward ways to earn a few bucks. As the name suggests, paid offers require you to pay out to claim the offer or to sign up for the service, but what you get back will cover this and add a small profit on top. If you’re signing up for a monthly service though, make sure to note in your calendar when to cancel it or you might find yourself out of pocket as they auto-renew each month.
Surveys can be super quick and take just a few minutes to fill out, or require around 15 minutes of your time. Five minute surveys pay $0.50 and surveys range from $0.40 up to the higher – and rarer – ones at $10.Paying out by the usual methods, Crowdology does PayPal and also vouchers. Most importantly, the minimum reward threshold is low so when you’ve earned $8, you can cash it out, unlike other sites which make you wait until you have earned much more money. The site offers prize draws from time to time for things like cinema tickets and surveys can be expected weekly.
The cost of living has continued to rise, while the average salary is still somewhat stagnant when compared to a decade ago, and this is why so many Americans have started to look for ways to earn money at home without having to invest too much time or effort. Family and friends come first, but with paid online surveys, you will not have to cut out any portion of your routine to earn extra money online, as you can instead go through the processes in your sparest of spare time. 
The other type of paid surveys CashCrate features are targeted surveys, which are available only to you and people who meet your demographic profile. It's very important that you fill out your profile on CashCrate right when you sign-up. Not only will you earn $.50 instantly, you'll also be eligible to receive these special surveys. So why are they so great? First, they'll often pay more than Daily Surveys. That means when you see one available, you should jump on it right away.
Oh I forgot to add that at least mypoints uses some of the listed above and others for surveys. vindale.com ( I have tried and was ok. I got paid but lots of work for not always getting into/doing survey although there are higher amounts you have to buy and so 35 might be like 10.00 after you buy things so be careful) and panda research is similar.
Global Test Market is a decent standard of what you're getting yourself involved in.  Their practices are not any more or less shady or reputable than almost any online venue – survey or otherwise.  Just like Facebook, when you identify yourself accurately with Global Test Market, you can expect them to use that information in any way possible to make a penny.  The great news is they inform you and ask for consent first.

While surveys vary widely in how they are conducted and used, there are a number of components that are common across nearly all surveys. Many of these common features have been studied in extensive detail by survey methodologists, psychologists, statisticians, and many other fields of research. The general process of survey research is outlined in the figure below.
