well kids like to play, so something that can bring together bitcoin and gaming
like puzzle that when solved reveal a private key for example
it is important that kids start to learn early some basic economy, at least something about income and expenditure
i heard about a new law for some countries that will make it possible(to teach them basic economy) in schools
I think I teach them like adults, because if we teach them Bitcoin is like a toy then when they grow up they will feel cheated,
so let's just know Bitcoin like they've grown up ..
