I did not get 600 followers in a month. My account is now 120 days old and I have 920F. So I averaged 230F per month. This is a good average and I am confident that it will rise next year. Don't compare yourself to others.
How did I do it?
- invest in steem - so you can give a few cents to your followers
- post interesting quality content on a regular basis
- don't ask for upvotes or follows as it will hurt your rep and you WILL get flagged
- share what you have learned about steem and steemit platform (tips and tricks)
- talk to the people on steemit, leaving meaningful comments on their content
- find your niche, the one thing you can do best to bring value for others
I could swear I saw on your profile yesterday that your join date was September 2017. Maybe I'm getting old.
Anyway, I agree with the rest of your comments. Asking for upvotes is one way to ensure a person will get none, at least from me.
