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.
I think it is hard to explain to children the concept of bitcoin maybe if the kids reach the age of 15 years old and higher they could understand how to use it because most kids now are technically equipped. But right it is really hard to explain to them and i do not know if they will be interested because they are still enjoying their childhood and all they want is to play and other childrens activity.
