I haven't thought to teach kids about bitcoin. Because they have their own world, and not to be taught to make money. Children are better at developing in a good social environment.
I totally agree with your stance it is not an idea at all to teach children about the bitcoins .this is something that is related to the finance of the house or a family and children being so young must not get under the pressure of increasing demand for earning in todays world. Inflation along with poverty and all other sectors must be handled by the mature people and let the children enjoy their childhood at their best.
It is not an easy task to teach kids about such a complex and advanved system.Children have a very little capacity of understanding so it ia difficult to create an interest in any work.Instead of bitcoin,they should take interest in physical games and in their studies only.When they will be able understand these complex systems then they should give more time in bitcoin and investments.
