I was also very surprised, why a project of this magnitude is very difficult to get listed in the exchanger.
Where as many other projects once completed of crowdsale, few days can be listed on several exchangers
Yes many ICO get listed on exchange few days after the crowdsale finish, but not always, i don't know this is only in my mind or else think the same, a several ICO finish at end of 2016 didn't get listed on exchange, seems they need a long time to prepare the token to be listed on exchange and sometimes make a bored.
