Why do people keep on assuming that Bitcoin is money? Bitcoin isn't money, it's an asset, it is obvious that the change in value wouldn't be the same as fiat. As it is an economic driven currency, while investments like Bitcoin is volatile and it is not determined by how much money is being printed out but how much is being mined. Gold is a very good comparison to Bitcoin, as they have the same properties as being an asset. Scarcity is pretty much what determines the price of Bitcoin, the lower the quantity the higher its price would be.
Since first day we are a solid believers and will continue to do so. That bitcoin as time goes by could be developed as a widely used currency all over the world. We just haven't find that way ..
