I haven't bought his course so I can't say if it's good or not. What I'm going to say is, there is enough free guides/tutorials out there that you don't need to pay for courses.
Second this opinion. Many traders that I know of never bought any cryptocurrency lessons. You just have to spend the time to read and practice on your chart. Lots of materials already available on Investopedia or Babypips, if you wanted to look for more.
You can even free many trading videos (course or not) on YouTube, such as DaytradeWarrior. If I were you, I'll not buy it and stick to those free materials.
I really agree, come on don't throw your money just for that, we are in the front, in the digital age that people rarely use this, if you really want to study hard I think here on the internet there is a lot of material available, about business, cryptocurrency and investment, not limited to the scope that we freely explore as you wish, all back to yourself how far seriousness is to seek knowledge, if your mindset is monotonous don't expect to be a successful person.
