No doubt for that. I am sure the investors will have a bad experience that will make them aware and stay away from the shit coin or the scam projects. They will not invest in them because they will search the other potential coins that will bring them a profit. I think the investors now become smart to choose the right coins, and they can research before they invest.
Yes, the coin with has no volume will be delisted from the exchanges, and that will not be too long to see the coin will disappear because people don't have an interesting to buy the coin. The project will die without any supports from people, and they will abandon the projects.
