The thermodynamic law of value in cryptocurrency is far more important than technology. The dot tokens have been fully issued, which is a deterministic soil moisture increase system. Technical changes have little impact. The impact of blockchain technology on cryptocurrency is only software engineering implementation and the money earned from selling products. The feedback mechanism and control theory of currency, as well as the design of nonlinear dynamics, are the soul consensus shaping of the value of cryptocurrency, which has a greater impact on the value system. People misunderstand Bitcoin, thinking that it is just a software engineering technology called "blockchain". And the real Bitcoin is a life order system that feeds on negative soil similar to human life. Nonlinear dynamics should be used more to design cryptocurrency systems.
