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.
BTC is the future of the economy and moreover the time is not far away when cryptocurrencies will replace the paper currency and everyone there will be using cryptocurrencies only, so everyone should be aware of BTC in present ,so that they could not face any difficulty in future and obviously children should be the first priority for its introduction because after all they are the future of the nation, so for explaining them, the best way is to introduce BTC as a subject in school curriculum.
