What do you consider enough followers to be an "influencer?"
I wouldn't say there's a specific number involved, it's really just more of a measure of how much your audience is engaging with you. I have almost 50k followers on Instagram, but they don't engage nearly as much as the people on Steemit.
I've seen Insta accounts that have only a few hundred followers get 50+ comments per post. All just depends on who cares enough about you to take a few seconds out of their day to acknowledge your existence.
Thanks though.
