because there is no binding responsibility, investors are still looking for any collateral and this is still subjective like buying a cat in a sack. If the ICO promotion is clearly regulated and not all of them can qualify, it won't be too chaotic now. The emergence of a too messy ICO can make many fraudsters infiltrate because there are no specific standards and it seems that it is still too easy to make.
I did investment with some ICO and gain nothing. I found few of them profitable but i am not well satisfy with them.For me ICO investment are fully risky and a lots of investors lose there money with ICO.
