Yes, I also think IEO is mist better than ICO. Where there is a score to make decisions about. This is the new era of IEO instead of ICO to investing and trading on such good projects. Specially i have lots of worst experience of ICO with their false road map and structures. So, really it's time of IEO.
Before investing in an IEO you should always check on which exchange they are hosting it as there are many low end exchanges which are also hosting IEO these days, also by paying a small amount of premium above the listing fees they also get inflated ratings by the IEO rating websites which also attract more people towards that scam and getting listed on these platforms is also pretty easy as well so that also increases the chances of getting scammed or getting false promises just like old ICO days when exit scamming was a common day to day thing to see.
