Best way of explaining is using the gold analogy.
But I think explaining it to a person in his/her early teens will be quite diffiicult. Best to wait till the person reaches late teens and then explain
Yes ,it is so hard to explain to them especially if they are not interested to waste just like 2-4hours a day spending time to bitcoin .
But its easy to explain if the teenagers are openminded with business and money and they know how value each money that goes on their hands
Yes, that's true my first time to tell my kid about bitcoin they dont interested. Now he is in college now they understand now about bitcoin, he interested to earn high profit. He learn how to invest in his subject in school. Now he joining in bitcoin for his future to become successful.....
