I am agree, i dont see the bad thing about IEOs so far. Many IEOs sold out in short time reflecting investor very interest on this sales model and sometimes could lead big profits when start listed in exchangers. I think about bad or good is depend on our own perspective, if we get profits, i think its good model but if we got loss we will called it as bad model
