So far, there's no sign that BMF.io gives any kind of official certificate or qualification to their instructors. It looks like anyone with solid knowledge can create and sell a course on the platform. That's not necessarily a bad thing, but it does mean you'll want to check out each instructor's background yourself , some might be legit experts, others not so much. BMF.io doesn't seem to have a strict vetting or certifying process, at least not publicly. Basically, it's more like an open platform than a school with verified teachers. If you're buying a course, it's smart to dig into the instructor's track record before spending your money.
