In my opinion, there is still ICOs nowadays that are very promising but because of the happenings of the last year, many of the ICOs are not doing what they have said and even in listing their tokens in the exchange. Maybe that's why in this 2019, they launch a IEO projects, which is you can invest tokens in the exchange so that it will automatically listed after the IEO. Well that's a good idea but in ICO we need to check the project very well.
I don't know where the promise of the ICO you say is? What I see is that the ICO is not appearing regularly in the market, replacing ICO, it is a new wave, IEO provides friendliness and safety for investors, projects always make sure they are listed, important is the value before and after being listed, that's what we need to care about most. 2019 has not so much expectation for ICO, another era has appeared, ICO should arrange luggage and live forever in the past, people will soon not mention it.
