1)IEO is safer and better than ICO because its not what anyone can just conduct ,to conduct an IEO the project teams must meet and comply with the exchanges requirements in order to launch the token sale .
2)contributors are protected by the exchange,why? Many big exchanges offering the IEO now are after there reputations so its not easy to launch IEO through them,if the project before them is not genuine enough the exchanges won't dare take the risk.
I think this is what many investors have been waiting for , better risk limiting investment ,IEO is the only way to go
,don't forget ,DYOR ,thank you
Still depends on the project and what problem are they trying to solve for the community, yes the crowdfunding will be successful, but after the crowdfunding, what will become the project, will the exchange has something to do with the development, so better if the project is really legit and what can it offer to the community.
