As you know Binance and other big exchanges have started IEO and they have good reputation but some little exchange that are unknown and not have any reputation, should not invest in these exchange .
when there are many IEOs that have sprung up at an exchange place like binance, I am sure it can provide a lot of benefits because we know that binance is a very large platform of exchange and it is not possible if they issue a bad IEO, surely they give IEO the best choice .
