There's no specific age to teach them about crypto, well, you just let them know that it exist, then you can tell them how to earn it in the future. I think it's good if he/she is in high school before starting to engage in the community.
exactly, there is no certain age required to teach kids about crypto. I think for as long kids are interested with it , we can start teaching them. But make sure that when they learned, they'll not miss thier schools homeworks and activities. and make sure that they will not use all their time in bitcoins.
