🤣 Nowadays, we are all in the field of charts and graphs. The main reason for the high trading volume of B2 is its good depth. Recently, I have been using B2 to brush Alpha, but there have been times when there have been problems. For example, yesterday I used 10000 U to brush six times, but lost 50 U due to wear and tear. Today, with the same amount and quantity, the wear and tear is only 7 U.
