Offering a course about sports gambling is a little different because it's such a niche topic, and I can see the value of getting information from someone who's highly experienced in the industry.

The problem with writing about sports in general is that many love to write about it for free, which makes it nearly impossible to make money from it.

Overall, I just feel like most courses are expensive, and most people paying for courses will not be able to make that money back, especially the ones buying courses about how to succeed on Medium.
