Nope shitcoins will always be a tool for profiting. Many devs and users are used to it so they know it will still exist in the long run.
I do not think this is correct. A coin that is pumped and later dumped, left and become totally shit is not like that. The money earned which is for the profit for developers and those that invested early if they are luck (because they can also lose), the money are lost by the people that invested later. For any coin which is not a store of value like bitcoin, as someone gain, so is someone lose.
