children doesn't need to know about currency,but teenagers does,and i think there's so many explanation video in youtube so don't wasting effort wasting your time when you can just give them about the link of video so they can learn from it,whether they will be interested or not,it's definitely depend on them
I totally agree with you. Teenagers are already old enough to see the value of currency. It will be interesting for them to learn about the differences between fiat money and Bitcoin, as a digital alternative.
Besides if you as a parent share values of the up-to-date crypto community you can become even more popular with your kid. At least at has worked out with mine.
