not all of them but most of them indeed were useless project/product until now,
i have been around here for more than 2 years and never heard a successfull project based on real 'item'.
what i mean is they're delivering what they promised to us,
the successfull one and the majority running their own project based on 'service' not an 'item',like program notification/alert,and etc.
Some ico are very innovative like health care, housing services and taxis, but it is useless if in the end they will not succeed in fulfilling the aspect of legality, they are trapped so deep that it can not grow. I know that the remaining icons are in non-physical products and services.
