In the digital money market, the experience of a seasoned investor has sparked my thoughts. Starting with an initial investment of 100,000 yuan to now having assets worth several tens of millions, this investor's success is not a coincidence. He once stated that the market is full of irrationality, but as long as one can control their own emotions, they can achieve substantial returns in this field.

After years of practice, I have summarized some rules of thumb applicable to cryptocurrency trading:

1. Entry Strategy: Be cautious when first entering the market. Build your position gradually to avoid rash actions.

2. Range-bound operation: When the price is consolidating at a low level and making new lows, it may be considered to increase the position. Conversely, after a range-bound period at a high level, a subsequent breakout may be a good opportunity to reduce positions.

3. Volatility Period Strategy: Consider taking profits when prices rise rapidly, and there may be buying opportunities during significant declines. During sideways periods, it is advisable to wait and reduce trading frequency. A slow decline may be a good time to gradually build positions.

4. Timing of Transactions: Avoid trading during extreme price fluctuations. Consider buying during a downtrend and selling during an uptrend; this contrarian thinking often yields good returns. In addition, pay attention to the differences in trends between the morning and evening sessions, and arrange trading times accordingly.

5. Risk Management: Calm periods in the market may give rise to significant changes. After a sharp rise, a pullback is usually expected. Pay close attention to candlestick patterns, such as triangle consolidations. In an uptrend, watch for support levels, while in a downtrend, be mindful of resistance levels. Avoid over-leveraging, and maintain flexibility. In the face of market changes, be prepared to cut losses or take profits at the right time.

Overall, achieving success in the cryptocurrency market hinges on controlling one's emotions and avoiding being swayed by greed or fear. Properly utilizing trading strategies and remaining vigilant at all times is essential to standing firm in this market filled with opportunities and risks.
