I love bitcoin not because its a buzzing word, but by the fact that it is based on a technology called Block Chain. Block chain is like a blocks/bricks on the wall that get cemented one after another after which there cannot be any manipulation as it happen and done intentionally by the intermediaries we trust.
So, the trust that we build on each other is called block chain in bitcoin. Without trust there can't be bitcoin, without hope there cannot be future... and both side of these coin is in bitcoin
