Many people think that Bitcoin is an easy way to get Rich quickly but children should be made to know that it is not only becoming rich quality they should transfer money and know about technology children she also be made to under that it is important for them never to share their personal information they are not to Told any one about their password and personal details they should know that they are many people who are scams and theirs online and they make use if such details to sted money they must be very careful before trusting anybody with such information
There's a way you said this that makes it sound too much because they are just kids, although I wonder the age gap for this?
For me, teaching children about Bitcoin through gamification and videos like the famous Cocomelon will be helpful.
Here, they will be taught about digital currencies and their uses, and the main focus Bitcoin, including how they secure or security in general but at this point they may not need to owe any amount but just have the knowledge. In the aspect of security, there should be a focus of teaching more about not speaking about parents or guardians funds including their bitcoin publicly and if they know the password not sharing with strangers or saying it publicly.
