Limited adoption for now, and fewer places to spend it.
Responsibility and risk go hand in gloves (many folks take it to be too risky to protect their funds themselves, so they don't like bitcoin for that because they don't wanna take responsibility

This is a very nice move, though I am not a fan of teaching kids about uncensored bitcoin knowledge. What do I mean, you said you thought them about the investment aspect, I do not agree with that aspect. The basic knowledge of bitcoin is good for them. Majority of the students are below 18years and would not be able to take responsibility of the consequences of investing in bitcoin. Most of them could risk their school fees in bitcoin and thereby stagnate their education. If you will teach them again, don't teach them about investment yet.
