better for Kids in elementary school would be to discuss the idea of get rich quick schemes: what are the chances to make it vs how are the chances to make the next paypal.
That money alone is not equal to happiness.
You are more mistaken than those who are having the idea of teaching bitcoin to elementary school students. They haven't even perfected their reading and writing skills, how can they even think of getting rich? They're just kids exploring the world and there's so much they need to learn and not finance is always an issue at any age. It is a foolish and short-sighted idea to think that it is possible to include bitcoin or financial education in the elementary school curriculum.
If you want to make money, you must first learn to be human, don't turn children who only know money without morality.
You are talking about 6-7 year old kids, I think they are talking about 11-12 year old kids. In most nations "elementary school" is until 13 years old, and that means kids at 13 years old could start learning more about bitcoin. I still think that high school is better, you would be about 18 by the time you graduate and you should be able to learn more things about crypto at that point but that doesn't mean that you are going to end up with a result like that.
It should be a lot better if you could avoid that and have a result that would be better. I believe that we are going to end up education one way or another, otherwise kids will never learn it and they will be too late when they are old enough to check it themselves.
