With someone, the definition of Bitcoin is too hard to understand so I wonder whether we have a more simple way to explain to them?

I dont usually open the topic to other person,only to those who just ask about bitcoin. So that, I can have all their attention and just discuss it slowly and simple. show them the actual amount I have and convert it to the local money we have in that way They will keep their mind working and thinking about how they can achieve those . That simple
