But hopefully your sort of presentation would at the very least spark an interest from them, ending up with them doing deeper research into it.
I couldn't agree more.
Same thing happened to me when I introduced Bitcoin to my cousin 3 years ago. I ended up just explaining to him just about on how to buy it, so in the moment he bought it and the price went down a little bit, he asked me if he already lost his money. So I introduced Bitcoin to him a little bit more about volatility and the market price movement. He said that it was too complicated for him and withdraw all of his funds instantly when the price went back to normal.
Lucky for OP to convince people to enter the Bitcoin world, but I think people automatically bought after he told them because they are only interested about the price and maybe they were thinking that its price never go down deep.
