The IEO doesn't need a bounty, just look at some projects sold in a short time. even in seconds.
binance is a prima donna because it successfully created several IEOs.
unfortunately it is not easy to participate in the IEO.
agree with you, but not the project will also be up bigexchange. If the project is not really good, it is impossible to be present on bigexchange. Through IEO from binance and other bigexchange, it is easy to see that the IEO is slowly killing bounty. Simple if the marketing from bigexchange is good, the project will not need to bounty anymore.
