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.
I am working for my grandfather to understand and try to check Crypto as an investments since he is still active in some businesses but he never give any importance,always saying that he is not interested and contented in His real business with real money involvement lol.Quote
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.
They are not concern about the wallets instead their mind is not ready or capacity to absorb another form of investments and they are believing in real money in hands instead of virtual.Quote
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. 
Maybe all i can advise is never stop,let Them see your progress and maybe in time they will decide in sideways.
