These two led me think about why you are providing your courses for free of cost? Why not I assume that you will be affiliated to some new sh*tcoins and may start recommending those coins to your subscribers/students? In my opinion, all altcoins and tokens are short living, for example, ETH seemed revolutionary but right now people use BNB or TRX for some reasons. So, when you teach about anything else other than bitcoin, that will not be good at least in my opinion.

Avoiding losses and maximizing profits are the things related to trading; again I hate this part for obvious reasons. You must empathize about the merits of decade long holding of bitcoin to all the level of investors.

This could be a wrong place to advertise for basics of crypto skills because this forum itself will cover all the skills of crypto space. Along with social media, I doubt anyone will find reasons to join your courses, no offence.
