Even if you leave the technical aspect of cheating tools (available so easily), the very concept of memecoin is based on dump

, in principle. Very rarely any meme-coin have any sincere community behind the project. Rest of them are just buying so that they can dump on others.
Yep. Communities of memes are going after two things - being trendy and known and funds to work with.
They don't need anything else and they don't work towards any utility whatsoever.
