I have met allot of people and some of them are already old (60 above), and for them, there's no room for improvements in terms of transactions as even bank transfer is hard for them to execute that they need someone to support them while doing so.
You touched on one very interesting question, but we should still put some things in place before we move on. When you talk about older people (over 60), several factors that significantly affect how they perceive new technologies should be considered. I think it's the first and basic level of education, because if you start explaining to people who have never used a computer what Bitcoin is, you won't get very far. The second factor is something we can call the
age factor, and it would refer to the fact that in some countries people at that age are still actively involved in society, while in some other countries people are already dying at that age (due to poor living standards, very difficult working conditions ...). When we look at Bitcoin as a unique idea that is in stark contrast to what these people have believed in all their lives, then it is not just a question of technology, but of habits and beliefs.
A dream of inviting our old citizens to bitcoin will not be possible if we ourselves lacks the fundamental knowledge about it, the best way to properly explain things is to first learn and use it. There's we can formulate various analogy to correlate terms and to lead them in the right path as they engage themselves with bitcoin. I believe that there's no boundary of ages for people to use it, that is why I like to learn and use bitcoin.
I agree that some older people understand new technologies like Bitcoin much better than some younger ones, but even if they manage to understand everything, how do you explain the problem of volatility to them? Personally, I would not want someone to suffer a heart attack because they lost 60% of their investment overnight, for which there is a great possibility when it comes to the elderly. Bitcoin is available to everyone regardless of age, but the question is how much older people are interested in changing their life habits.
