I think it won't be so hard to find an exchange with IEO service. IEO is a trend of this year. So, if current exchanges will refuse Romad, they will find another one. The problem is that we will wait longer than 4 months...
They (exchanges) need to make sure if they will only listed some legit token on their site, so that's why it take long time to get listed. Afaik, you don't need to wait for 4 months to get listed in 1 exchange, because you can apply your token on many exchange on same time
yes, i do not think it can be cost 4 months to list on a exchange , if not because of exchange listing problem , so that what make they do postpone Program
