Anything can happen in the currency circle, so you must do a good job in fund management and risk control, and you must not blindly trade with heavy positions. One mistake may seriously damage your vitality or even cause you to be wiped out. Before entering the market, you must first consider what to do if you make a mistake and lose money, instead of always thinking about winning money. You are not a god and cannot be 100% correct. It is better to admit your ignorance and ignorance than to be arrogant.
