You can earn points in a number of ways: by taking surveys, referring friends and recruiting via a blog or dedicated website.
You'll be rewarded for every survey you take part in. The amount of points awarded varies according to the length of the survey, which can range from 3 to 35 minutes.
With Hiving, points are awarded immediately upon completion of the survey.
You can earn money by referring your friends. It's a simple way to increase your rewards. As soon as your referred friends take part in their first survey, your points are credited to your account.
With Hiving, only active referrals are rewarded. False referrals are not taken into account. There is no limit to the number of referrals you can make.
