Yes, definetely a scam. He is not even playing in the video and he is not proving to the watchers that his system works.
Quoting from the youtube video:
I could ask you to pay 10 dollars, i could ask you to pay 20 dollars, i could ask you to pay 100 dollars, i could ask you to pay 10000 dollars

another goddamn sociopath
That's probably why he doesn't want people to ask questions (which is part of the things I find suspicious about the video). I guess he doesn't want to say much and get exposed. If you are doing what is right, you shouldn't be afraid of questions from potential customers
