Starting something new is always the hardest, but it will be easy eventually. If you are going to introduce crypto currency to people for the first time, I think it will be better to use more analogy so they can understand it in terms that they are familar with. It is a new technology so we should correlate it to fiat and the existing financial systems first then as you discuss the features and difference of it from the existing ones, they already have an idea of you are talking about. It should be easier that way. Then after that just give then materials or websites where in they can read more about it.
