As a data and tech-driven blockchain finance company, TokenInsight spares no effort to establish its own data center based on the interests of investors and has recorded the transactions of 24 mainstream exchanges in periods from 00:01 on September 3rd, 2019 to 22:35 on September 21st, 2019. Later, we conducted a qualitative and quantitative analysis of the "wash trading" by using power-law based quantitative model and two comparative analysis methods.
