Selling in the crypto world is the most difficult, not because of the method itself, but because of your unwillingness to let go of profits and your greed for making a little more. However, those who have not experienced the entire cycle of bull runs and bear markets do not know.

For example, in a bull market, your assets can reach tens of millions, but after a good night's sleep, they may drop to 7 million. Would you sell or not? Newcomers definitely wouldn't sell, as they would feel like they've lost 3 million.
An old man who has lost money will definitely sell, because he feels that he has made 7 million, and the other 3 million is simply taken back by the God of Wealth, so let's just offer it to him.
Many people join some groups, and every time the group becomes very lively, they start to dump. This dump indicator must be accurate. When most people make money and get excited, it's time for you to withdraw.
But don't rely on this indicator to catch the bottom, the emotions of fear and loss are difficult to quantify, fall 10%, fall 20%, or fall 50%. It seems to be almost the same.
