You should probably have put your op better, i believe you want to know if older people around us are interested in BTC and if they also buy some coins for themselves. This will depend on the part of the world we are talking about, in my own opinion, it will be harder for older people to get involved in BTC in third world countries, or in locations where education is poor, and there is little or no literacy in tech or the digital world.
However, even if older people in some parts of the world understand what BTC is, it would be hard for them to trust it or to buy it, they will most likely call it a scam and stick with older forms of investment that they are used to.
You are correct, not every parent can invest in bitcoin because bitcoin has not yet begun to function, and it will be very difficult to persuade them to invest because they will say it is a fraud, and they will most likely not have time to research it to determine whether it is real or not. Since the introduction of bitcoin, our parents have been in business, which has allowed us to grow and learn. now have a good understanding of bitcoin and plan to invest.
I don't think some of our parents will benefit from bitcoin because they are already getting old, and whatever you didn't start when you were young will be very tough for you to do when you are older. won't have time to run it. You can't get the patient to run it because you'll see it as a waste of time, and everyone knows that bitcoin is not an easy thing to profit from because you have to leave for a long time, and some of our parents will disagree because they prefer daily income, which is why they engage in businesses that generate daily income. So I assume he won't be so easily to confuse parents to invest in bitcoin.
If your parents think bitcoin is a scam and don't trust it enough, you can introduce them to bitcoin ETFs. I think that's enough to prove and convince them that investing in bitcoin is legal and safe. In addition, investing in bitcoin through bitcoin ETF will partly avoid the troubles of storing bitcoin yourself, everything will be much simpler.
But if it were me, I wouldn't encourage or support my parents to invest in bitcoin, because I don't want them to have to face the stress caused by bitcoin's volatility. Our parents are the older generation and now is the time for them to rest, not the time for us to force them to continue making money to take care of us. So I would never advise my parents to invest in bitcoin even if they wanted to invest in it.
