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.
I agree with you that's why i have made thread about the ICOs/altcoins must be followed by us, it is my own thread where i have spent my time almost more than one year ago to find great ICO projects, and i have shared it on this forum here
https://bitcointalk.org/index.php?topic=4496788.0 to give information for all of community cryptocurrencies and in my own analysis not all of ICOs projects become an April fools.
