IEOs are a useful way for startups to raise capital for their venture and the requirements for major launch pads generally ensures they provide a quality product with a unique innovation and real world applications and professional marketing, and new platforms like Tokinex don't require any hosting fees for these endeavors which will likely produce better results for this crowdfunding model
Any projects that can be courageous enough to list on IEO platform are really not start u projects. Do you know how much these exchanges demand to list them on their platform? That fee alone is more than enough to start up a mini project in a mini village and feed the whole community for years.
Most start up projects usually start with zero fund which is why you see them go on ICO that requires no commitment, this is the reason why I do respect any project that has not conducted ICO before and could boldly register on IEO, it means that they mean business and it is certain that they will have a good package to deliver to their investors.
