The easiest is to blame bounty hunters for dumping instead of admitting that the project has no working product with real use case and active development.
If the project are good and worth to hold, i think the will ignore the price. Many factors why investor or hunters dump their token and market condition is one of the reason. Beside that, the project itself is important to gain investor trust to hold, if worth to hold for long term, i am believe holder will not sell it at cheap price
