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.
Since price can’t go up all the time.
It is nature. You can't blame them since they hope, maybe because of the thought that it could be just like bitcoin that went up even it went dip every time. I believe it is good to be hodling the coin if you beleive it is for a long term investment, otherwise, short-term trades must be analyze well since you could lose the value of your asset in a very short period of time, specially if you're investing on a shitcoin.
