Starting at an early age does give you an advantage at any platforms. But the ability of holding those knowledge in your head depends on your age or your bairn's capability. At the age of ten? I guess that's a bit too extreme.
But on the other hand, we recognize money from an early age, which is less than 10 years old. If we give the basic knowledge to those children, they might be able to get a hold on to the facts. When it comes to advance knowledge, they can learn them later on. The main focus should be to make them familiar with the concept. After that, their curious mind will do the rest. So from my POV, it is a great idea to have. By doing this, we may see a generation that will accept Bitcoin with their open arms.
