Well all I want from the new coins is that they should not be scammers one. They should be perfect in al sense just like the IPO's who offer proper projects, real world applications etc. I guess having such qualities in the crypto coins would be the great thing. I guess the ICO project should offer the exchanger before they can even start with their crowdsale etc. I would say having ICO's over the exchanger can be good deal because it can bring us surety that we are not going to get scammed at anytime as we have the option to trade our coins immediately if something goes wrong.
