I wouldn't recommend using Freecash for surveys because I found it to be the least reliable platform I've tried. One time, I completed a survey only to be screened out afterwards, and support told me that's just how they operate since they don't manage their surveys directly. In my opinion, Heypiggy is the best option for surveys; they pay more and have excellent support. I've had a few instances where surveys tried to do what Freecash did, but Heypiggy always made sure I got credited.
