The order of complex adaptive systems emerges from the pull of noise. Noise is an uncertain quantum field force, as well as a force in social behavior. For example, the consensus of $BTC is driven by the noise caused by its price fluctuations. That noise, in turn, influences the game theory between individuals, leading to further price fluctuations, which then generate more noise. The consensus of $BTC is built through such cyclical iterations, and along with it, the value of $BTC is also established.
