I think IEO is good and more reliable than ICO. In IEO there will be fewer scams. But I dont like that in IEO only exchanges and investors and start-ups can earn, and theres no place for bounty hunters.
And why is that bad. The only reason for bounties is to help spread the word about a project. If a project already gets advertising through an exchange, then there is potentially no need for bounty.
It should be seen as a positive that IEOs are likely better for investors since they are actually spending money on the project.
