You will confuse to tell what bitcoin or cryptocurrency are if youself didn't have knowledge about it. You have to know the basic thing about bitcoin and also you have to know the basic thing what blockchain is. I believe if you know the basic of both you will easily give a learn to people who has an interest to bitcoin. Giving a knowlegde to other people is important but before you give a knowledge you should overcome first what will you convey. If not, there will many question posed to you and you can't answer it and other people will doubt to know more about it.
Theres a popular saying having half knowledge of a subject is as good as having no knowledge of the subject, in your case I feel you need to do lots of research before you tell people about bitcoins. What I feel is youre trying to make it very complicated, hence I would suggest you to stick to the basics of bitcoins. The best way to do it is to gift them few Satoshis, as this will teach them how to use bitcoins as a currency, how to operate a bitcoin wallet and then theyll automatically learn on their own.
