Yes, I definitely agree with you. It should be their headache that either they want to learn or not about bitcoin. As the modern technology has been increased too much now a days, so all things can be gained from the source of internet. Bitcoin is a source of income. So, it is not needed for the children to learn about bitcoin in that age. Because they don't need to earn money.
bitcoin is not actually a source of income it is not a job but a digital currency we don't have to be worried if they are interested to know bitcoin, we can guide them to learn all the details and information regarding to it but we don't have to guide and teach them about how they can earn it, it is indeed that at that age they have to learn how to earn because their focus and their time would be only dedicated on that activity .
