The innovation and regulatory coordination of digital currency is an important proposition in the new era of Fintech. There is increasing competition between traditional currencies and new digital currencies, so a spontaneous game model of currencies is analyzed. By introducing the role of financial coordination, this paper revises the evolutionary game model of digital currency innovation, and analyzes their competition strategies through case and simulation. The results show that: first, the dominant result of digital currency spontaneous game is that both parties tend to digital cooperation strategy. Second, with the introduction of financial regulation, the dominant result of digital currency tripartite evolutionary game is that financial institutions tend to participate in coordination and both currency parties tend to cooperate. Third, the choice strategy of currency is more sensitive to the changes of willingness to participate in cooperation, cooperation costs and cooperation benefits of financial coordination. The selection strategy of financial coordination institutions for digital currency is more influenced by changes in cooperation costs and incentive return in the process of participating in cooperation.
