I think it's a nice idea to drive adoption but there are already plenty of courses, albeit no single 'bulletproof must recommend' course.

Great if you want to do it as a charitable course but no way it would have any significant impact in the wider market.

Where I think this could be quite effective is in a local community.

In some localities I have seen people promote it and now quite a lot of stores accept bitcoin. Makes it not only easier to spend it for existing holders but also makes a lot of new holders i.e. more liquidity in the locality.
