Well, once again, if you only write in the topics that Medium favors and use really good click bait headlines, like "How a Earned Buttloads of Cash on Medium...." yeah, you might make it into the .0001% that make a living from Medium.

But, if you just write quality stuff that you are passionate about, don't expect much from Medium. It's all about the algorithms. Good and great writing takes a backseat most of the time here.
