i will prefer join IEO on top exchange altought public respon is flat, i believe the team and developer of exchange not listing IEO without do any research before, that mean with top exchange as backed up usually the IEO will success too.
We started to forget the basic, what makes some project so special and valuable? product and community.
IF the project gets a flat response from the public, that means the project is not attractive and there will be no demand. An exchange is not a liquidator but it is a place for the buyer and seller to meet.
even if you are listed in Nasdaq, as long as nobody is willing to buy it. The price and the project will be gone in no time.
and even if it gets listed in an unpopular exchange, as long as the exchange is working fine. The project and the price will survive and it might get better.
