The idea of teaching bitcoin to high school kids is a good idea, but their principals must agree that you will teach them. If they accept and solve the problem that there are no computers, your mission will be successful.
A support can also be that you teach about bitcoin from a mobile is also very easy and perhaps young people have more within their reach.
You encourage me with your joy and it makes me think that we are protagonists of a good change for the new generations.
Please update the thread with your experience with the boys. It would be great to know the results.
