Yeah that is an excellent idea as nowadays kids have access to Internet and they prefer watching cartoons and youtube videos.So introducing interactive videos about Bitcoins would be a great idea to make kids learn about this digital currency.If kids learn and grow interest in bitcoins it will help bitcoins to grow even further,as kids will be the future pillar of our world.If they understand the importance of bitcoins then the future of bitcoins ruling over all other currencies is very near my friends.
