You registered on this forum in less than 2 hours ago and your brought up poker courses, is that not funny and look more like scam attempt? others.
when someone sells a course this person is not promising that all students will earn a lot of money, this person is not doing magic, he is just passing on some knowledge and with that knowledge each student will further refine the knowledge he has acquired and if the students go or not earn money with this knowledge, it will depend on the commitment of each student. I think this has nothing to do with scam. And if someone claims they bought the OP course but couldn't earn anything, that person can't accuse OP of a scam either because OP is not promising that people will make money, he's just selling course (knowledge)
welcome to the forum, how long have you been teaching poker courses?
