What do you say when asked this question from a friend who has only heard its name mentioned a few times in the news and has no clue. I find myself lately taking the easy way out and suggesting google. I would prefer to give a clearer answer, but usually saying something leads to more questions and more confusion.
If someone could point me to a twitter type answer that would inform and twig their curiosity, i think it would be a better outcome.
I have been always asked that question when I tried to share knowledge about bitcoin and its future. It turns out that still some people cannot understand what bitcoin is after you explained everything you know. I think there are people that are really not meant to be into bitcoin. Let us just leave it that way. Maybe if they have at least a little interest in profits of bitcoin, they can learn it themselves by just searching on the internet. You can also provide some proof of what you gain in bitcoin, maybe a screenshot of your wallet containing the equivalent fiat of your bitcoin balance can make them interested.
