The loss was stopped at 420, and this decision seems decisive, but it was actually taught by the market. Originally, I wanted to buy the dip with a divergence pattern, but I didn't expect the reversal speed to far exceed expectations; as soon as the situation changed, I had to withdraw immediately. This is the reality of trading—no one can guarantee every trade will win. Those who tout guaranteed profits and never losses are, to put it bluntly, deceiving themselves and others. The volatility of the crypto market is evident; rather than fantasizing about certain victory, it's better to learn to respect risks and implement timely stop loss. Sometimes, leaving the market alive is much smarter than stubbornly holding on like a gambler.
