Old human beings are the first to emerge as inclined to scams if adoptions comes around, and I suppose like crypto is a spectacular way for these guys to get screwed.
I don't be conscious of how this is going to work out for old human beings who cannot even know private/public keys let on my very own hot/cold wallets.
Your pattern of laying emphasis by means of repetition on the grouping as per "old human beings" almost leaves me with the impression that, they were of a different specie other than humans. Of course that would be inaccurate but, I still feel there is a world for the old even I a fully crypto functional society.
As oppose to what you've stated with the old being victims of crypto scam; this is often the case due to ignorance. A fully crypto innovative system would mean more awareness for the young and old which reduce crypto scam to a minimum and the technology about payments would be made simpler and easy to operate. It's already easy as it is but, people are yet to grasp due to lack of exposure.
