if you want to buy IEO maybe you can use an exchange other than Binance, Bittrex or Kucoin
Other than binance, Kucoin, and Bittrex, so do you mean it's better to choose IEO in a small exchange?
I think if you take IEO in a small exchange it will be far more risky, because the project could be scam because usually small exchanges are more concerned with money than investor security
Possibly, that's why most of the success in IEO are coming from big exchanges, small exchanges will have to gain reputation in order to increase their trading volume and even if the project is legit, but people will still look for a decent volume, an IEO coin that is good for day trading hast a better future ahead.
