I know that many good ICO's around and some were very promising. HOwever, there are other ICO projects to which now looks like an April Fools who's team always talk to much but in the end of the ICO period all they have to do is to be silent, list the coin of the project and then dump the project. This is why we really monitoring from these guys to keep their promises before, during and after the ICO period.
Oh well, that's what majority of ICO is, so don't be surprised.
And now the IEO is born, it might be difficult for those projects that are purely design for pump-and-dump because investors grew tired and since we have a new hype with IEO and much promising then don't be surprised if ICO will be obsolete in the coming years.
