I read only two articles, so I have nothing to comment on. Your writing is fine. Sharing is caring, even if it doesn't make you a big buck. This is mainly because you haven't had the chance to connect with fans who share your mindset.
Don't Give up, Keep writing; you will meet them one day, Trust me.
It depends on your goals. I will say that this formula is applied :
good content + traffic = money on this platform.
The weightage of good content is only less than 5% here. Many writers will find a way to get more traffic to boost their income because the content is cheap.
My recent articles can answer your questions. If you're looking to understand the system that Medium uses, this article is worth your time.
