You're right mate, bounty promotion isn't enough to have gotten the needed announcement of the project to the entire public for investment. With the ICO been conducted with series of projects that has been done before now, there seems to be a link between the ICO and the investors. Many investors sees ICO as a means to scam them from their belongings even the means of IEOs too. This has be more reasons why projects promotion need to be more sincere to the investors than ever to redeemed their image. Personally, am scare of investing in any project promoted through ICO and IEO, I don't want my funds go into tin air without a return.
