If you just got followed by this account then you will be receiving some extra votes. The intention of this project is to get more people to minnow level (currently 592 HP) and to encourage posting.
We have some criteria for who gets votes. You need to be commenting fairly often and getting some comments on your posts. You should not be powering down as that will mean your HP goes down. Some people were just dropped from the list for this reason.
Your success really is up to you. Once you reach minnow the votes are likely to stop from this account and those who follow its train. You need to build a following by engaging with others. You need to find the community of those who share your interests. Make it fun for yourself.
Hive is not a guarantee of rewards, but everyone has the potential to earn.
