You can build a Blog and make money from this but boggling is not longer what it use to be so you need new strategies to fit into your Blog.
First things first:

1. You need to build your Blog in such a way that it's easy to find, follow and share (always keep that in mind).
2. Incorporate more than one type of media meaning not just text and pictures, also incorporate gifs, videos, to make it entertaining for the viewer and keep them engaged.
3. Build your reputation and following by guest writing for others in the niche and linking back to your site, the more influence these people have the better.
4. Monetize! You can offer your own info products on the subject, consultancy, affiliate products, you can do ads for other people and you can even get sponsors for your Blog. Don't limit yourself to just one form of monetization but also don't make it look like NASCAR because it becomes annoying.

Also with this kind of topic it's great to deliver value on a consistent basis so Social media and Email are a must for you.
