On the one hand, the enthusiast inside me really wants to tell my child about bitcoin and cryptocurrencies. So that a child from a conscious age understands that it is not necessary to pay intermediaries in the world, and there is justice in blockchain technology, thanks to the genius of Nakamoto. But there are much more disadvantages here.
Children do not need to load their heads with unnecessary knowledge, children need to study at school and then at university.
Yes, it will be possible to tell them already in the middle classes, but the main thing is that they do not perceive bitcoin as a roulette where the meaning is only in money.
And it is important that by that time bitcoin is not banned in my country, then my story about it to children will be useless.
