You are right, binance and Huobi are the best for IEO right now. if there is an IEO is a small meeting or with a bad reputation then forget it immediately. it will take our money for free.
Yes, that is very clear, IEO who is in a large exchange is definitely better than IEO who is in a bad exchange, because this concerns the reputation of the exchange and the reputation of the team that made IEO itself.
