Some people refuse to take profits when their coins and tokens are surging so high.
Because greed let people keep on waiting for higher and higher value for there coins and end up selling at dip.
You are right that some people cannot accept profits due to greed even if they get a chance. I don't know how much their coin price will increase and they will be satisfied. We must accept profits whether small or large. Because maybe the opportunity will come for you only once.
