This is a marvelous idea. I love the gamification aspect. Duolingo uses that as well and it works great. With blockchain technology a massive upgrade with financial benefits for the users. You really have something big here.

However, I think you might limit this system with the concentration on financial education. You could open this to all sorts of decentralized topics and let people educate each other with your coin. You could develop the financial course you are suggesting as the examplary course for other course creators. I guess, that would probably require a hive solution to keep quality up.

I am just thinking outloud. You have a really cool project and I wish you success.
