As a rising star of cryptocurrency, the white paper "The Future Development of Pi" published by SCIREA, an international journal, is characterized by openness and innovation. The first strategy is to skillfully solve the exchange problem between pi and hundreds of legal tender, so as to achieve the most meaningful leap. The second is to establish a long-term automatic savings interest rate system to make Pi the most competitive world reserve currency.
