First, how much money you make depends on the money pool. Second, it depends on how many upvotes or likes you get. Third, it depends on the value each of those votes might hold as different votes may have different weights meaning more weight to a vote might mean more money or voting power or value. Fourth, it depends on how many downvotes you might get as the downvotes can counter the upvotes. For example, you might get one dollar worth of crypto from upvotes. But then downvotes might counter the upvotes to bring down the total you might earn.
Fifth, the value of each upvote and downvote may depend on how many votes they made in total. The more you vote on posts, then the more each vote may lose value in the same way each slice of a pie gets smaller each time you slice out pieces from a pie. Your voting power is like a pie. Voting one time is like eating the entire pie meaning 100% of your voting power goes to the one vote. Voting two times might be like cutting the pie into two pieces as in 50% per vote. The value of each pie or your voting power may depend on the first factor, the size of all the pies meaning the total size of the money pool of this Hive blockchain and when I say money I mean crypto which you can try to withdraw so you like spend the money or whatever.
