I want to categorically tell this set of people that Bitcoin is the way forward for you, bitcoin works for everyone, and the system was designed in a way that every interested person can participate.
Bitcoin allows you to be your bank and be in charge of your money with no interference from anyone. Participation is dependent on your interest, not your identity, that's to say that everyone can be involved without their identity known. Note that blockchain technology guarantees your Bitcoin security, so don't be afraid just give it a trial but with a little money I believe you won't regret it.
Even if bitcoin is a viable solution for anyone who doesn't believe in centralized banking and financial systems, are you sure they really can consider the risks involved in bitcoin?
I don't fully believe you can convince them that bitcoin will be a safer store of value than gold or other investment assets. I think bitcoin is only suitable for those who are able to understand risks and manage risks well. While they tend to prefer to keep their fiat at home, it's clear they wouldn't trust anything more currency that doesn't have a physical form includ bitcoin.
