Everybody must have noticed a method that works for them, for me I know that people like to use new things that they believe are better, I noticed this recently so I explain bitcoin to regular people as an improved payment method, and that always gets their attention first better than explaining it as something that you can invest in to get money. That always gives the vibe that it is something dubious since there are very schemes like that. After people understand and see the improvement that bitcoin has brought then I introduce to the aspect of bitcoins that still hold profit by buying and just keeping it.
