Also, good thing to check out is steemworld.org , put your username in and you will be able to see your voting power and how much your upvote is worth. when you upvote too much and are so small your vote is worth zero. Within a 24 hour period a new account can do 10 upvotes to maintain 100% voting power, and if you like 20 votes it becomes worth zero and has to be left to recharge. You can do more than ten some days or up to 15/20 if you know you will be less active the next couple of days. It is a little confusing at first but once understood is actually very simple to check and make sure your vote is actually helping the authors you vote for!
