In the face of the big dump in the crypto world, the correct course of action can be summarized in the following core advice:

First of all, managing emotions is the prerequisite. During a market big dump, panic and greed are the biggest enemies. Please strive to remain calm, avoid panic selling, and don't blindly chase highs due to rebounds. Strictly adhere to the trading plan you set in advance, rather than being led by the market emotions.

Secondly, risk control is key. Be sure to invest with disposable income, ensuring that the loss of this capital will not affect your normal life. At the same time, avoid frequently averaging down during a fall, as this may lead to deeper losses; a more prudent approach is to only add to profitable positions.

In terms of specific strategies, consider operating in batches. When the price falls to a key support level and shows signs of stabilization, you can buy in batches instead of making a full investment all at once, which helps to average out costs. If the market trend is clearly downward, going with the trend is a safer choice, and do not attempt to catch the "falling knife."

Finally, use tools and maintain patience. You might consider adopting a dollar-cost averaging approach by investing a fixed amount regularly, which can help smooth out your buying costs and reduce the pressure of timing the market. At the same time, during market downturns, you could consider staking your assets to earn a stable passive income while waiting for the market to recover.

I hope these suggestions can help everyone better protect themselves in the volatile market and seize opportunities.
