Abstract:

Step behavior refers to the behavior of the signal transmission due to external shock, financial assets because of step-by-step supply and demand will also show step behavior, then the cryptocurrency market closely related to the financial market also has step behavior? In this paper, the daily data of the ChaiNext5 index from January 2017 to May 2021 are selected to identify the step behavior of the digital money market by the pure lag step GARCH model, and the phenomenon of the anomaly of the class step signal in the digital money market is found. In the analysis of the behavior characteristics of step in digital money market, it is found that step behavior shows agglomeration, time variability and asymmetry, and the overlay effect of pulse response decreases gradually when positive and negative step behavior alternates. The causes of step behavior are explored from the impact perspective of “extraordinary” events, and “extraordinary” events are divided into five categories: politics, economy and technology to explore the response of five kinds of events to the digital money market. The results show that the digital money market is most sensitive to economic events, followed by political, technical, social and legal events, digital money market has strong digestion ability to media attention and social step behavior caused by investor herd behavior, poor digestion ability to the step behavior caused by cryptocurrency algorithm technology, and the strong positive pulse that China's strict regulatory policy intervention will produce in the lag period of digital money market. Regulation of the digital currency derivatives market will drive the digital money market to become more mature.

Key words: cryptocurrencies, step behavior, rush response, “extraordinary” event
