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.
I've taught my parents how to use a smartphone before and I didn't find it difficult because my grandparents were always trying to find out if they didn't know. But maybe they have a hard time accepting overly complicated explanations and I understand it. People over 60+ are pretty much the same, but I guess it will depend on how we can explain it to them because their world is already too different from what we experience. That also applies to people who don't have a broad understanding of the times.
If crypto gets into the hands of people over 60, it will need more attention and help to understand it but as long as you can teach simple things like receiving and sending crypto and how to buy and sell, I think that will suffice. The important thing is not to teach too complicated things so that they get confused. But they might be curious to hear more from us.
