I just started getting into forex but as I have read I see that there are a lot of bullshit creators out there so if yall can suggest some good creators with good free courses for me to learn that would be appreciated

The best free resource is an old school library with these things called books made out of non-eink paper.

I’m not even joking. The problem with online courses, YouTube, etc. is there’s too much damn money involved. Anyone can learn just enough to sound smart, put up a course, and make six figures a year. But if you write a book, you might be lucky to ever get that.
