Sorry, I don't think IEO will end this soon! Do you see any other plan comes except some scammy idea like IMO, IAO! Harmony, Tokoin, SERO, GowithMe, VSYS, MATIC all these gems came through IEO! A lot of investors are waiting for a new project from Binance, Kucoin! These exchanges are making good profits too, so, these big exchanges will hold the IEO for a long time, they won't let it go like ICO! You can say all projects that did not come through the good exchange, they have vanished or nothing to give in the crypto industry!
Good projects are not those that have brought every minute profit in the form of doubling your capital, which you were allowed to contribute to the exchange. And those projects that are popular over the years and their services are in demand, which means that the price increases not because of the desire of some large speculator.
