You bought 10 yuan;

You are afraid when it falls to 8 yuan;
Fall to 6 yuan and you die hard;
You are numb when it drops to 5 yuan;
You ignore it when it rises to 7 yuan;
You're tempted when rise to 8 yuan;
hesitate when rise to 10 yuan;
You regret falling back to 8 yuan;
Sell it back at 10 yuan;
When the price rises to 12 yuan, you should close all positions.
The price rose to 20 yuan, 30 yuan, or even 40 yuan, you're being foolish, going crazy, seeing everyone around making money, so you're catching a falling knife at a high price again.
In the past decade, I have seen 99% of the people around me entering the market at the peak of the Bull Market, and holding on during the Bear Market downturn. Without exception, they all sell to break even before the arrival of another Bull Market, and then enter the market again at a high point.
Tao is the law. Law is the cycle, and human nature is also a cycle. Therefore, the essence of enlightenment is to understand human nature and the cyclical laws of development. #$BTC$
