We are in a season where most ICOs don't meet the expectations of their fundraising hence institutions are even doubtful in organizing their own ICO project. It seems we are in a revolutionary period where people and institutions are gradually shifting from associating themselves with ICOs but rather choosing IEOs or adopting well established cryptocurrencies. It's all good for the world of cryptocurrencies.
IEO is practically no different from ICO, except that the project tokens receive an exclusive right to place on the exchange, they have very similar problems, such as non-quality projects and problems with the SEC. Accumulation of low-quality projects can adversely affect not only the exchanges themselves, but also resume the fall in the capitalization of the cryptomarket.
