Also it is important not to forget, that today, children better focus on education and skills that they can use or be useful after they graduate from university or school. Crypto - useful knowledge, but besides investing where could a child use it? Trading? CEX dont allow underage to use it. Use crypto wallet to make payments - places where it is possible to pay with crypto are still too limited. Coding, creating project, developing? I dont think that many kids will be so much interesting in that at young age. Make NFT - probably, but interest to pixeled graphic editor will end soon.
