One of the hardest things to do is to try and convince someone that is set on the fiat currency to look into the world of crypto ,and in order for crypto to be a well adopted payment system it is necessary that the education on it increases drastically as well. How do you think older generations can be convinced of the cryptocurrencies? Especially since they only tend to believe in currencies they can physically see and hold, such as their fiat currency. In my opinion, i think demonstrations are the best way to convince these people, as seeing is believing, and showing them the potential and possible purchases may help them in understanding the system and considering it.
