Binance and Bittrex are the only two exchanges with the IEO now (may be others are warning up). Twice Binance has succeeded with its launchpad but I think Bittrex has issues with its own - not sure if that has been resolved. So, OP how do you get (force) other exchanges to have IEO if they aren't planning on that?
There are lots of exchanges doing IEO's. But i also didn't convince the op's post. It may end up with a scam attempt.
Every exchange in list have a strong analize group, if project - SCAM exchange will refuse EIO. A lot of exchanges are very sensitive to their reputation.
