In cryptocurrency investment, position management and trading cycle adaptation are crucial. Large positions should grasp medium to long-term trends, capturing potential market movements through macro and technical analysis, enduring fluctuations for substantial returns; small positions focus on short-term swings, entering and exiting quickly based on micro market conditions and high-frequency indicators to achieve steady compounding growth. Both essentially involve balancing risk and return, requiring precise judgment and strict adherence to strategies to achieve investment goals.
