IEO is good but i think there is some more work needs to be done. But we are moving in the right direction and soon we'll be at a stage where we'll be having projects where our investments can be safe and reward good profits.
Back in 2018, ICO had been the word of the mouth and had created great buzz in the market as well. But that trend was smashed into pieces due to the fake and dubious projects and that was the start of IEO which had been pretty much profitable. If you are lucky enough to participate in the IEO token sales, you could make some great money.
