Bitcoin is difficult to explain. I also felt difficulties in understanding bitcoin for the firs time. Let's share how to explain bitcoin to children of teenagers. In My country I can say 98% children don't know bitcoin. In fact, bitcoin can be future money. If the children not familiar with cryptocurrency or bitcoin, how can they face the digital era in the future.
As I agree with you, it's hard to understand bitcoin if we explain to teenagers or children that it's harder to understand that their age is from 18 above to understand what bitcoin is and to have them know about it for We explained to them that they understood about bitcoin and what its importance.
