IEO is an advanced form of investment compared to classic ICO. This is a great opportunity to invest in reliable proven projects. This minimizes the chances of getting on a scam project and losing your money. I myself was losing money on ICO and now I started investing in IEO again. By the way today there will be a very interesting IEO from the Gexan project. If anyone is interested in investing, I recommend to consider this project. These guys are very cool!
