Almost every coin created these days is designed for one thing and one thing only - to make its creators some easy money. They are relying on newbies and the gullible to throw money at their project so they can make a quick buck and disappear.
I agree with the fact that this is the truth with many projects that don't have, and probably will never have, a working product and a real use case. But I don't agree that we can apply this reasoning to all the altcoins in the market; I think there are some interesting projects who can potentially give nice returns to investors when the market will start a new cycle.
