Nobody wants to fall into the same hole, so in my opinion the ICO can't do much even for years to come.
ICO is like a scam project that offers benefits but ends in huge losses.
ICO or IEO, at this time, have not shown their quality after entering 2020. I just think that people want more convincing sales from IEO. it's just that, when compared to ICO, IEO is very better for now. I quite hope that in the future there is a new and more reliable sales system, but for now, I only choose and rely on IEO.
