Trading is simple in essence; there are only four key points.

First, you must dare to cut losses when wrong. Many people fall here—holding onto the cost price stubbornly, ultimately deepening the loss. Stop-loss is not about giving up; it's about leaving yourself a way out.

Second, you must be able to hold onto the correct position. This is even more difficult than stopping losses. When the market rises, you want to take profits quickly; but after selling, you watch the subsequent gains and feel regret. After choosing the right direction, maintain a steady mindset.

Third, position management. No matter how good a coin is, reckless trading can be suicidal. When to add positions, when to reduce, your risk tolerance must match your actions.

Fourth, execution. Once the plan is made, follow it strictly. You can't change your strategy because of temporary fluctuations, nor can you increase leverage out of greed.

Currently, with BTC, ETH, and SOL showing obvious volatility, it's a perfect time to test these principles. Mastering these four points will help you survive longer in the crypto market.
