Bitcoin is hard to explain. I also experienced difficulties in understanding bitcoin for the first time. Let's share how to explain bitcoin to children of teenagers. In my country, I can say that 98% of children do not know bitcoin. In fact, bitcoin can be future money. If children are not familiar with cryptocurrency or bitcoin, how they might face the digital age in the future.
Yes, bitcoin is hard to explain especially to my friends, they are hard to get the concept of bitcoin. So for me teaching it in children is a good idea because while they are in a young age they can eaily get the concept and idea of bitcoin. For me, teaching it slowly and detailedly is enough for a child.
