For any activity to be a full-time job, it has to cover all your bills at least and leave you with some extra money to get some small luxuries. Going with this, Surveys On The Go and competing surveys for money cannot be a full-time job because the reward per hour is very low. Those who earn the most from these sites get about $500 on the good months (and even this is not consistent). It is safer to say that Surveys On The Go is a good side gig to earn some extra cash to pay some bills, but not one to replace your main source of income.
