Friend, I would suggest you watch this video posted by Jerry Banfield a year ago:
Jerry Banfield was a kind of Steemit mogul, but he did a lot of money with Steemit last year and after cryiptocurrencies crash this year, he quit Steemit and sold his Steemit account (I do not suggest follow his Steemit account); despite all this, I consider this video is good to know about how works Steemit. Another trick: transfer some Steem from an exchage to your account (I think 10$ at least), this would give you more Steem Power and could increase your Steem incomes. Bye, happy posting!
