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 agree with this one. Most of the trading done in the crypto currency is all about the personal experience and nothing else. I have seen people giving away the advice in here based on their personal experience. That is they tell many people they did this and they did that and they got this kind of experience etc. Just some random strategies from everyone which starts with different types of trading ways that can be followed to earn big money over the time. You dont need to have professional lessons or something like that because you can follow simple trading hacks which can make you gain nice profits over the time.
