Hi Mattie, thats the issue that steemit has at the moment. Its articles are heavily focused on a few topics, not necessarily mainstream.
Having said that there are some great travel, photography, poetry, even philosophy. I think the crypto stuff is what gets the biggest bucks at the moment, but forget about that. Write about what you love, what your passionate about, build followers. It wont be long before Steemit goes mainstream and the content base broadens. Thats when your hard work will pay off!
