It really matters on what you mean when you're talking about this redefinition of money, I (personally) don't think that Bitcoin is going to end up being the currency of the world as so many would like to think it's going to be. But I DO THINK, that Bitcoin is going to bring innovation to the world currency stage -- be it with blockchain tech, and so on and so forth.

So even if Bitcoin does die, I do think that the world is going to gain the knowledge that a decentralized currency is possible. This is the most amazing part in my mind.
