@cryptocharmers There's a lot of good thought in this post and a good comment below. @eroche I just found your posts and each one leads me to another one. I like what your write about. Sorry for commenting on an old post, but I wanted to share your information with a friend. I am following you now, so I will see your fresh posts more often. And I like the idea of making a coin as a learning tool, especially as a class project for a high school or college.
