To qualify for referral rewards when joining Rhino through an invitation from friends or family, you must add their referral code to your account. You can do this during the account creation process. However, if you forget, you can always add it later through your account settings.
Add Referral Code:
Navigate to the 'Home' tab
Select your profile in the top right corner of the screen
Click 'Referral Program'
Select 'Enter Referral Code'
Copy and paste your code
Click 'Next'
