So my question is:
Do people hodl just because others are HODLing?
No, every trader/investor has different targets, they survive not because other people hold. They have a goal of maintaining their assets through the ups and downs. When the price reaches the initial target, they will release it according to the concept of buying low and selling high.
Why so people hold rather than sell and buy again when low
They have considered all their decisions wisely, some of them have also predicted price movements from time to time.
It takes patience to control your emotions when you see big profits, when in this position I will usually sell some of the assets I have and hold some of them.
What is your major reason for HODLing and how do your survive the bear market?
Actually the method is very simple. After putting some assets into the wallet, leave your assets there without doing anything for a long time. Then you can check the portfolio again when the time is right to sell it, believe me patience very often ends with a smile.
