I think the topics which do best on Steemit are about the Steemit. How to succeed, get more votes, improve the quality of your posts, get more followers, tricks and tips... And, of course on the topic of crypto world in general.

As I am no way an expert on Steemit or crypto I choose to write about my life, and make people laugh, plus try to motivate and inspire people. I think it is all about writing something you are passionate about and being patient because it takes time to find the right audience.

At least this is my humble opinion. Have a great day. :)
