It's good the project is thinking IEO but one thing is choosing a good exchange for the IEO.
You are very correct with the choice of exchange, as the choice of exchanges these days somewhat determines the overall turnout of sales/IEOs done in general. Recently, Binance and the likes have been pulling weight. All the best guys in the IEO outing.
Everybody cannot go for Binance. I guess it could be very expensive too. But lot more exchanges are getting good also.
