Research firm TokenInsight recently released the "Exchange Real Trading Volume Report (below)", which surveyed 24 exchanges around the world. The results showed that the real trading volume of 8 of the exchanges was less than 30%. TokenInsight recorded the transactions of 24 major exchanges between 0:01 am on September 3, 2019 and 22:35 on September 21, 2019, and then used self-developed power-law-based quantization. Analyze the model and refer to the comparative analysis method proposed by Bitwise, and perform the “brushing” analysis under the qualitative and quantitative two-pronged approach. The TokenInsight official website will be launched on the “Market Real Trading Volume” monitoring page in the near future. Market participants can use this page to view the real-time real trading volume of each exchange; and, simultaneously develop two models to identify the “brushing” behavior. , will be released after the completion of the supplementary report.
