This is not a very simple thing, it might be very simple to introduce to them, but it is very difficult to know exactly how to operate. In fact, I also spent a lot of time to learn about BTC, but now I am still not sure that I know BTC.
It's best to get their attention first and then let them learn for themselves, if they're still interested.

Show them the potential of bitcoin. You can also give them some value, as well as share the knowledge you have.
Show them the returns bitcoin can bring to their investors.
