It isn't SO popular atm I supose. Older people have no clue what bitcoin is. I do think it would stay as "popular" as you think it is now though. I really can't give any reasons for this but it's just a feeling :-)
Even if its not popular to them, do you think that Bitcoin would be in any use for the elderly? Or will it make there life better or easier? I guess not because Bitcoin is designed for this generation in which are people who are technologically inclined that they can adapt easily compared to the elderly in which they would take much time to learm and understand Bitcoin. Additionally I think that they are better of using fiat currency in which is the most simple way to pay.
Exact is the point. Bitcoin would be more of a use to young generation then the old one. Let them have some peace in their last days and enjoy their lives. Why dragging adults in technology when it would be so troublesome to clarify everything. Honestly, I can't.
in fact pld people (my father) will be a little difficult to know and understand about bitcoin, then I do not force them to learn bitcoin again lol. back on the topic that you are saying that bitcoin will lose popularity when bitcoin prices become stable. I think its right? because many people say that most bitcoin users only aim to benefit from fluctuations only, and me become example
