If you do not receive any referral bonus, it is possible that your referrals are not sharing their internet bandwidth with Honeygain.
To check if that is the case, open Dashboard, and choose Transactions history view on the left. You will be able to see all credit transactions that are happening on your account. You will also be able to see from which referrals you receive a bonus. Please be noted, that due to security reasons, only a part of the email is shown. If you do not see any transactions coming from your referrals, but you do have friends on the Referral list, it means that your friends do not have the Honeygain application open and/or are not sharing their internet bandwidth with us.
