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.
Well there may still be some interested in these poker courses but to think that it also comes with a price, that would hardly attract new players to enroll and learn, as there won’t still no guarantees to win because poker games are games of chance and luck. With that, it’s better to learn on your own through video tutorials and apply what you learned when you decide to start playing in casinos.
