My kids love bitcoin, they have had wallets for 3 years and have introduced the friends to the concept. They are all swapping bitcoin and exchanging things for it. It reminds me of the ted talk by andreas which i have posted below. " try explaining KYC to these kids when their 18", lol

It sounds great that your kids already loved bitcoin and they are introducing it to their friends. what supprising about it is that they are using it on exchanging stuffs for bitcoin . It's pretty hard to teach kids and convince them to use some thing that is not too easy to comprehend so I am amaze that you made it successfully cause even your kids had adopted bitcoin because of you .
