Most times it is very important to be mindful of most sort of pumps witnessed in the market. Most especially when a token that looks questionable with low volume all of a sudden starts pumping hard, in my own opinion, when such happens it is the best time to sell that is if you are holding and move on, rather than buying because following such pumps always ends in a terrible manner. A dying project can get pumped by the team to attract users and then dump on them, it has happened many times and will keep happening because there are people who are easily swayed by pumps without minding what the project is all about or what the use case is all about or what is even causing the pump, what they care is to get their gains while getting trapped in most cases.
There are some coins whose activities seem doubtful from the beginning. As you said when a coin pumps a large volume with low volume then the next step of that coin seems to be risky. I have seen that there are many traders who do not research the coins well before buying any coins and prefer the market price of those coins.
As a result, they face huge losses in the future.
