The main problem is nowdays are everyday many ico launch which is on same project or topic, we can call copied project (not all but mostly) are launching everday and I think ico will not end until we find solution for this and for this we need some advance technology who will helps to find clone or copied concept of ico's then ico projects are getting fewer and geniune that will helps crypto community to make good and then we might see ico will end or few when no project will copied.
