If a minor can understand Bitcoin then the answer is obviously yes but I think getting them involved should be under the supervision of an adult because minor tend to make the wrong decision when money is involved, if you are going to introduce Bitcoin to a minor let it be under your care and let them depend on your guidance and support. It is better to teach them Bitcoin from a young age and also learn and work on their emotions and learn to be patient and consistent.
I dont think its about the learning part now, A minor can learn bitcoin very well and understand if they have that interest, but I think where the Challenge comes is with having acesss to money to buy and hold bitcoin, well I believe there are minors who are given pocket money by there family and friends, I think when they have that money that is the only time they can be able to buy and hold bitcoin, but on a personal basis, I dont see what stops a minor who have that motivation and zeal to learn about bitcoin, however I have decided that as soon as I have kids, I will start teaching them about bitcoin when theyve gotten to the age of understanding things, I can go as far as starting a bitcoin portfolio for them, but the Challenge would be that they dont mess around with the Bitcoin investment when theyre grown up.
You have a points here, and in my own perspective I would love to support the ideas of teaching our children more about money at early stage. Because that can brings a difference changes if bitcoin is even part of the learn habits, so developing the habit at the early stage is much more important, because that would definitely help them to understand how long-term patience works and they will have a good thought towards that, than making them viewing the bitcoin as a cash out asset, where they will be taking money anytime they wanted. If at all, the ideas of stacking little amount for them at younger age to the time they would grown up older is a great ideas, that alone shows the real example of how consistency works. It's just now letf for them on how they would be in control of it when becoming an adult, because if all the lessons been thought to them weren't followed as they grown up, there would be a big problems, and if they follow all the teachings, it would serve as a guiding decisions in the future.
