I am sure that most of kids and adults don't know what bitcoin is, but that don't mean that it will be too hard for them to understand it. If they know paypal, just tell them that it is similar - virtual money. They don't have to know anything about blockchains and other confusing things.
Youngsters cant effectively comprehend what is bitcoin, whats the procedure, how it works. In any case, I think, the most straightforward approach to disclose bitcoin to youngsters that its an digital cash, monry on the web and demonstrates a few recordings how can it functions. Shows some video that youngsters can without much of a stretch get it
That's the point. I am sure that it would be hard to understand even for 13 year old kid, older ones might understand it more but not young ones. But like i said, they don't need to know that. They can use bitcoins even if they don't know how they work, while i am sure that they know or at least will understand what digital money is.
