Editing your post

By a friend of mine covered everything in the next post

A general and first explanation for users

Voting Power - Each user in Steemit has a voting power and according to his Steem Power every vote of that user is worth money. The Upvote / money he gives does not come out of the wallet but from his voting power. Which can be seen on the following website: https://stepennow.com/ (change to your username on the top right).
Link to the calculator https://steemnow.com/upvotecalc.html, where you can see by your parameters how much your vote is worth.

Reputation Score - (located next to the user name) Anyone registered gets 25, this number you want to keep it high. The higher it is, means you are more exposed and your exposure is high. High exposure is one of the keys to success. Of course, this number can rise or fall.
What brings it up? Followers, successful post with Upvote(The higher the cumulative amount of SP from the people who upvoted you) (posts can also be comments). What lowers it? A lot of posts with a few upvote.

I think there is a lot of helpful information here, you should keep it and share it with your friends. Good luck to everyone!
