Will the current hype & acceptance of the initial exchange offering (IEO) over the erstwhile initial coin offering (ICO) affect the opportunities for bounty hunters?
What do you mean affect the opportunities for bounty hunters? There will be plenty of opportunities, don't you worry and I don't think it will slow down a bit.
Can a project on initial exchange offering (IEO) still fail or exploit people?
Yes, IEO can still fail because the market is free and there will be competitions and we have want we wall life cycles of a project, and after the initial hype, the project will simply die down, regardless if it is an IEO or ICO. As far as exploitation? I will be honest with you, as long as there are bounty hunters willing to accept measly payment, then there will be projects that are going to pop up and make use of bounty hunters.
