Either ICO IEO or STO, this shouldn't be what you will rely upon to get great benefits from new projects,what makes a difference is the thing that the teams are attempting to construct ,the inquiries you should begin posing to yourselves is what innovative idea will the new project offer crypto space ? Also, how great are teams records.
Many investors are complaining that they are at lose investing in some IEO projects ,these investors believe that all IEO projects are good and should be able to double or triple their ROI which is not possible unless they actually do good research on the projects first ,lack of research will always leads investors astray
Sincerely, this thing is not investor's fault. As long as no scam project wears a particular coloured flag to tell everyone it's a scam project, theres really no way to know which one is legit even with all the beautiful wrote ups about the project. It's actually not investor's fault at all. Those setting up scam projects just needs to have a rethink so that the confidence of individuals in this crypto space can be guaranteed in whatever investment they are making
