All the surveys I have taken so far, don't pay much. It actually takes forever to harness huge sum of money by writing survey. Am in doubt, what's your experience with survey and which is the highest paying survey in 2020.
I don't know about 2020, but I know about 2021. I recently completed a survey on a phone application worth € 7.50 and I was paid instantly (it took 35 minutes per hour to complete the survey)
