Typically, it would be best if you were 18 years old or above to become a regular survey taker and make money online. That’s because most survey sites require people from this age group. Also, most of these sites give cash rewards through PayPal, for which you’ll need a bank account. You can go for sites that let teenagers and kids aged 13 or more join their platform. Here, parents can redeem their children's points for them, so they don’t have to handle cash.
