You describe money and more specifically money where it is used as a Means of Exchange. Yes it is the means by which we can exchange our surplus goods and services for those others produce and is the fundamental enabler of trade. But Bitcoin is not mostly being used as money. Bitcoins use has been slyly shifted toward being predominantly used as a speculative commodity. Being defined as a commodity by taxation regimes has strongly driven this shift. Using Bitcoin as a speculative commodity is much less threatening to the bankers and governments who hold the fiat monetary system hegemony. Bitcoin being used as a speculative commodity also makes Bitcoin much easier for them to capture and control. Within 5 years a majority of Bitcoin could be held by institutional custodians. In terms of its original stated purpose- as a censorship resistant P2P payments protocol Bitcoin is not succeeding- although it still can be used as a means of payment it very rarely is.
