Today I made several trading strategy steps to take advantage of market momentum. First, I monitored the trend of Bitcoin's price, which experienced a sharp decline, then opened a buy position when the price touched a key support level. Additionally, I diversified by buying altcoins with medium-term potential. In this process, I always set profit targets and loss limits to control risk. I record and evaluate all my transactions so that future strategies improve. With this discipline, I can keep the portfolio stable even as the market moves fluctuatively. #TradingOperation
