@Rruchi man, you are right you can't just introduce bitcoin to them easily when they are still growing they won't get interesting on it or won't focus with it because they are not mature enough to understand it.
Catch them while they dey young. To be honest that saying no be lie at all o.
The truth be say most children are more open and willing to take advice when Dem still dey small. Na for that young age dey go dey look up to you whether as a parent, an uncle, an aunty etc. Once dey don mature to maybe teenager or adult, e go dey very hard to tell Dem what to do. By then Dem don get their own independent mindset and most times no go wan even listen to your advice.
That is why for me e dey very appropriate and right to introduce them into Bitcoin or other crypto asset an early stage. You don't need to bore them with the complex aspect of crypto like analysis, trading, Blockchain, whitepaper talk etc. You fit start with basic talk like
concept of saving,
value and importance of Bitcoin and other crypto assets, maybe
how not to fall for scams in Bitcoin or other crypto assets. From there I tell you my brother them go pick interest, if you they teach them this thing try dey use pictures dey follow am, cos children learn more and faster with what they see.
These kids fit no grab everything wey you dey teach at once but if you sow that seed early you go dey very surprised with the later outcome. Personal I wish I was introduced to Bitcoin at a very very early age. I for don pass where I dey today.
