I have been here on Steemit since June 2017.
I have learned that the absolute best way to earn Steem is through Curation.
The Key is to Power up 100 % and find the best "New" posts to upvote at the 4 minute mark with 100 % Voting Power.
Maximum Steem Power is the Key.
Even with 10,000 Steem Power you could be earning $400 USD per month.
Don't even worry about earning any Steem with your posts.
