I don't see how important this is, my parents are no longer young that they should be bothered about their future life infact soon they'll depart this earth to a better place so they shouldn't be concerned about what they future holds for Bitcoin to invest in it. My father has owned some Bitcoin but he'll soon sell them and I'm not against that, what he should be bothered about is getting the best out of life before it's too late. The age bracket that should be investing uncontrollable are the youth, technically we have the future ahead of us and need to be financially prepared for it and by investing in Bitcoin we're doing that.
Our parents investing in Bitcoin is less important compared to us investing in Bitcoin or other youths in our family. My parent did invest in what was valuable in their youth years and it favoured them to have a better life for their children. I'm to replicate that by investing in Bitcoin and other valuable assets that I can depend on to make my future journeys relax and not still struggling because I didn't do what was important when I was a youth but wasting my time chasing pleasure. My father owns some Bitcoin but he isn't serious about it like I'm and that's cool.
