We must respect the market. Many big players who have been in the market for over 5 years have been buried in this wave of market fluctuations. Large funds should definitely not enter contracts; it is really very unsafe! In fact, in the financial market, as long as our risk control is not good enough, the unexpected will eventually come, whether this year, next year, or later, or even 10 years from now! Therefore, a strong theoretical foundation + strict risk control is the most crucial.
