Your thoughts must be appreciated. The most precious period of a person's life is his childhood. What a person can learn in childhood, becomes his wealth for the rest of his life. I think that the nation which can accustom children to books is the most advanced nation.
The bitcoin comic handbook is made for people of all ages. You will find this book available on Amazon. But for 7 to 11 year old children any cartoon videos are more interesting than writing books. You will find many cartoon videos related to bitcoin on youtube. Which can be a great way to introduce your child to Bitcoin.
If you can teach your child right about Bitcoin at this age. But your child will gain a much better idea of when to hold and when to sell bitcoins after a while.
Teaching children about Bitcoin is a good way to spread the news about the potentials of Bitcoin when we trade it or invest in it.
Like we know that children learn very fast, teaching them will help them to understand what Bitcoin really worth and it will also help them to spread and advocate for Bitcoin. Any slightest opportunity we have, we need to use it and teach children on how to invest in Bitcoin and also how the market moves. This is a way of empowering children for the future of tomorrow.
But, of course, I hope the OP doesn't overdo it. We can't push the knowledge or interest of bitcoin at such an age just because we want them to know it, but of course they are in their stage wherein they tend to explore and be curious, so it may be a good time to introduce or influence them in bitcoin, but we can't push them to take an interest in that; they have their own free will, so even if we introduce and influence them, don't expect that they will be interested immediately or adopt bitcoin. But the OP's intention is good because if he is committed, then if his cousin shows interest in bitcoin, then I know he will guide them as he is the influencer. But the thing is, I know it is hard to find a store or book store where you can find a comic about bitcoin. Maybe on the internet you can search, or if you searched for a print copy, then maybe you can print it yourself.
There's always that right time and its true that it wont really be that ideal that you would really be that forcing your kids on telling about Bitcoin or crypto because even on how hard you do make out some explaination
but if their interest and self awareness on things arent still that matured then it would really be pointless or useless because it would really be that easily forgotten. This is why it would really be always better
that you should be telling them on the right time if you do see that it is really just that prepared to hear and having that possible interest. Telling them forcefully would really be that stressful.
Just like on waht had been said that it would really be taking some time, they would neither be normally be dealing with crypto or knows about it on the time that they would be able to encounter it
considering that recognition and adoption we do have in the market is really t hat increasing year by year on which it isnt really that shocking that they would be able to encounter
normally along the way.
