I'm looking for the easiest way to make old people understand Bitcoin more thoroughly. I want to let the elderly know about the "Bitcoin revolution", yet I find it quite challenging to explain it to them in a way they can understand how it all works. There are some wallets that have a "user-friendly" interface, but even the basics of sending/receiving Bitcoin can have a steep learning curve for the older people. A Bitcoin wallet with built-in accessibility features, could help even elder people with vision or hearing problems to use the pioneer cryptocurrency in their daily lives.
If you happen to know of a way to make old people understand Bitcoin easily, please let me know. Any suggestions or recommendations will be highly appreciated. Thanks in advance.

Since you are targeting an old people it's better to have an old one to explain this to these old people because they understand each other's language, you can pick one older guy to train him one on one to teach old people, you can hire him or pay him to teach other old people, the old guy that you are teaching, should have his own module suited for old people.
