If you count comments I bet I made at least 1,000 posts that earned 0 maybe even 2,000. Without bots I might be at 2,000 or 3,000 posts/comments that earned nothing.
Steemit is not easy to make money at but even if you make nothing I still think it is better than Facebook.
I think there is a potential for steem to moon though. If steem does have staying power in 10 or 20 years a steem might be worth $10,000 or more.
