We just have to accept the fact that there will always be people who will not understand crypto fully, they will continue to exist for a very long time.
There is a great douglas adams quote that says "in technology peoples approach are the same, whatever existed when you were born were the natural order of things, whatever comes up between your age of 15-35 will be exciting and new career opportunity, whatever new after you are 35 is against natural order" and that's what I believe.
Nowadays that 35 is probably closer to 50 because tech improves very fast but I still think people approach things still the same. There are still people who do not know how to use mobile phones, not even saying smart phones, literally mobile phones that were first invented, the really old 20 year old versions.
