In the cryptocurrency market, it is a process of accumulating sand to build a tower: how can one achieve stable profitability? A person's energy is limited, and reaching the top in a niche area is already quite challenging, and it's sufficient without needing to become an all-round champion in every field. The same applies to trading; it is unlikely that one can excel in short-term, long-term, oscillating, and trending trades all at once. It is improbable that all directions will reach the pinnacle, even if there are trading prodigies who span multiple directions: I believe one should become very skilled in one direction and achieve stable profitability before cautiously considering adding some extra attempts. Therefore, at the beginning: focus on choosing the most precise direction and persistently continue with it, sticking with it for the long term. Continuously summarize and reflect on what others perceive as mistakes. Perhaps what becomes your most correct might not have a clear boundary between right and wrong. Choose a trading model that suits you; only with focus can miracles be created. Directly share valuable insights from Ping Zhiyuan.
