When I first entered this circle, I thought that mastering cryptography principles, understanding candlestick patterns, and obtaining insider information would lead to success. Later, after losing my first real money, I realized that the reality is far from romantic—decisively cutting losses and strictly controlling position sizes are the iron rules for survival.

After experiencing a complete bull and bear cycle, I gained new insights. Those traders who survive by luck often share a common trait: they never borrow money or leverage, simply and straightforwardly surviving for a long time. Compared to those who seek quick profits, this "bare survival" philosophy is particularly valuable.

Later, after reading too many stories about overnight riches, I truly understood what risk means. The final realization is: having your own trading system is far more important than luck, and not being driven by FOMO is far more important than blindly following the trend. These concepts may sound old-fashioned, but every person who can consistently make money has learned these lessons through experience.
