Then you probably want to look at how Steemit (and later Hive) did it, you generally keep writing your content but within your group/network just make sure you share your power around and grow together until you're all able to promote your own posts.
Not my advice, just how it's done. I really don't like spamming content if it's not relevant.
Alternatively, if you really feel you're a good writer and have unique perspectives, I'd go for Hackernoon, and if you get 10 or more published or have a good rate of 90% approval, then you network from within. Doesn't give you crypto really like steemit did but exposure.
