As per the research report i read on LinkedIn someone posted it few months ago he mentioned that 85% icos are just for raising money and they don't have potential product for future development and for benefits for stakeholders.. one more thing most of ICOs do not able to give any profit from investment. that's why I don't want to invest in any of ICO.
Based on my experience, you will only have a good chance to gain profit from ICO or investment in crypto project if you have a deep connection with the project's team.
Inner circle and inside information have always been the key here.
