Last Friday, the trading volume of exchanges such as Coinbase, BitMEX and Coinan increased sharply. According to Skew's chart, the average bitcoin volume of all of the above platforms peaked on Friday. In addition, the volume of transactions on all of these exchanges tends to peak between 12 and 16 o'clock in the Coordinated Universal Time. During these peak hours, the average transaction volume of BitMEX soared to $150 million, Coinbase was $5.5 million, and the currency was $23 million. This time is 7:00 am to 11:00 am New York time, 8:00 to 12:00 Beijing time, 11:00 to 3:00 pm in Canberra, and 5:30 to 9:30 pm in Indian time. Therefore, it can be speculated to some extent that most of the trading volume of these exchanges comes from the East.
