Surveys can be helpful as long as it's just an extra income and you don't depend entirely on them, for example I can earn around $150 a month with them due to my region, but with that alone, you can't live, you need more income, earnings with surveys are limited even in tier 1 countries.This is because it could be considered as part time job or extra job and not a real job for a living for your family means for some bucks like 5
$ a month or 10 $ a month or these staff. This is the sad truth instead.
