That's good for you and your child, that means you have to teach and introduce bitcoin to your child. But kids usually just want to have fun and a pedestal to learn. So you should not force them to know and do what you do in bitcoin. Let them do what they want. If you want to keep bitcoin for your child but they do not want to know, you can entrust the bitcoin you keep to your relatives and give it to him to give it to your son someday.
A very good opinion and I totally agree with your opinion.
If you already have a lot of bitcoin then invest your children to get the results of your efforts during the bitcoin during this time, for a while your children do not tell first because it is still a child and let your children play and fun and fun it is important that you collect a lot of bitcoin for your child sometime in the future.
