BitCoin, as explained to my 5 year old

me: You have piggy bank?

kid: Yes papa!

me: how would you feel if i steal from it?

kid: very very sad. then i cant buy hoverboard on my birthday

me: what if you can hide that piggy bank in whole wide world, like some part of it in America, some in Africa, some in Europe and India?

kid: than i have to make a very big robot with very long hands to open it

me: well that’s BitCoin! we take all money and put in so many small piggy banks…
