Selling poker courses or whatever gambling related courses with a new account and no reputation known in this forum or in other platform is not a good start and as you are selling the courses is that there are courses that can be found online for free and even some app that are free to use where you can practice after learning the free poker courses that you have found. I think it will be hard to sell the poker courses you have as many people wanted to save money by learning from free poker courses.
That's what I think, but OP, how can you promote your courses well if you have all these shortcomings? I think that OP should take a trusted member, with experience to give him the course for free and that person of faith that his course is legitimate and that OP can be a trusted person, so that someone can buy his safe course, It's what comes to my mind, otherwise it's kind of hard to promote. I'm not saying that you're a difficult member to trust, but these things lend themselves to thinking about any kind of thing, and since we all have to take care of our money, I'm very attracted to your offer, but that's why I'm making the suggestion.
