Young people who know about bitcoin and use it can teach people about bitcoin because it can help spread the word about bitcoin. In this technological era, it seems like it would be easier to spread the word about bitcoin and it's a good move if young people who use bitcoin can do that because, at the very least, they can help bitcoin.
Although it will take a long time to receive bitcoins, everything should work out fine with the help of the internet. The hope is that more people can accept bitcoins like us.
Have ever tried to explain old people how to use smart phones? I mean people over 80 are hopeless in that situation, maybe a few exceptions but I can guarantee you 95%+ of them do not get it. People over 60+ right now have probably a 20-30% missing as well, and people under 60 usually have it unless they are too poor to buy one which is harder these days since it is getting dirt cheap.
So, crypto getting at the hands of people over 60 will not happen that easily, under 60 is doable but over 60 there will be maybe 10% of all the people who are 60 that could understand and start using it. That doesn't make sense to spend resources on that. Just focus on new kids growing up every day, there are more and more new kids aging between 15-20 years old. Remember crypto is around 12-13 years old from the concept now, even older to be fair since it was first 2008, there are kids who were born after that and own bitcoin now.
