Beginners will be very difficult to make money on this.
You will most likely fail.
And I want to ask you yourself, how does this your suggestion actually help him out?
To make him see the most essential aspect of crypto, which is that it is essentially a zero sum game, and that the idea that one "can make money from it" implies that others must lose an equal amount of money ; and that if you're new to the game, most probably you're on the losing side.
This is entirely different with a question like "there are so many cryptography texts and books, I'm confused, I want to learn cryptography". "learning cryptography" is not a zero-sum game. When one person acquires more knowledge, it doesn't mean that another person has lost that knowledge. So there, every beginner can be helped. It makes sense to "want to lift your confusion to learn cryptography". But "wanting to lift your confusion to make money with alt coins" is something different. You need to be warned that there must be as many losers as there are winners, and that, if you're a beginner, most probably you will be losing.
