You can teach a kid to be part in bitcoin by convincing him/her to save or invest in bitcoin .Nowadays kids are so curious on how to save a money so you can teach them to do or to be part on it
- I do not think it is necessary, to teach the child about the knowledge related to bitcoin is too difficult, even I can say is very headache, children will be difficult to concentrate and care about what we say. I know that children are very curious but they very quickly bored, and Bitcoin is need patience and effort, so it does not fit their age, they need more time to mature and have enough patience, and we should only teach them when they have the excitement
