Find the links. Between blockchain and what else you want to write about. There’s always a common thread. I’ve written about data analysis and music and sports. It all hangs together. Be like Kendrick Lamar, who made an album about gang wars, blackness in an era where black lives are devalued, and his own insecurities with fame, in that order. They all sounded different but they all were part of a unified whole. That’s the trick. Do that.
