Dumping after listing has become a major problem which needs to be solved. Many developers are afraid of listing because of getting dumped. Good projects do not dump easily. Devs should get to work and give regular updates.
Secondly, tokens bought and earned by hunters should be released in batches, this will relatively stabilize the price.
Listing on exchanges with great volumes will equally be of a good help
it is very true that every good coin and token will never be disposed of for free only by the owner, so to avoid dumping after listing is really necessary to work and provide the best for the project and investors.
