When are referral rewards earned?
Referral rewards are earned only when your referred users earn rewards for their answers or voting contribution.
Referral rewards are 5% of your referred user earnings. So, if your referred user earnings are 0, then your referral reward will also be 0.
So what should I do?
In case if you have invited your friends, family or colleagues, then you can also guide them on how they can earn on Masmic. Talk to them about their experience on Masmic, clear out their doubts or misconceptions and encourage them to write or vote answers and thereby leading them to their first reward on Masmic.
If you are a YouTuber, try giving out an honest overview of Masmic rather just showing it as an easy way of earning. You must ensure that your viewers understand that only the most relevant answers are rewarded and thus, just answering or voting any answer will not fetch them any reward.
